The hybrid metal matrix composites were fabricated with aluminium alloy 6061 as the base material, reinforced with boron carbide (B4C) for enhanced hardness and molybdenum disulfide (MoS2) for self-lubricating properties. The key tribological parameters considered are normal load (10 N, 25 N, 40 N), sliding speed (0.5 m/s, 1.25 m/s, 2 m/s), and temperature (50 °C, 125 °C, 200 °C). They were systematically varied to analyze their effects on wear rate, using a pin-on-disc tribometer. A Box-Behnken method was employed to evaluate the wear rate with interactions and quadratic effects of the considered tribological parameters. The results indicate that sliding speed and load significantly influence the wear rate while temperature has a secondary but notable effect. Regression models were developed to predict wear behavior, with response surface plots used to visualize interactions. Additionally, scanning electron microscopy (SEM), x-ray diffraction (XRD) and wear morphology of worn surfaces is studied. This study highlights the potential of the Box-Behnken methodology in optimizing process parameters with minimal experimental trials while providing detailed insights into material behavior.","PeriodicalId":18366,"journal":{"name":"Materialwissenschaft und Werkstofftechnik","volume":"57 2","pages":"124-133"},"PeriodicalIF":1.1,"publicationDate":"2026-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147579690","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study examines the correlation between microstructure and abrasive wear resistance of metallic alloys under tumbling abrasion, with a focus on practical applications in mineral processing. The novelty lies in establishing systematic links between carbide morphology, matrix hardness, and wear mechanisms in environments of quartz sand and iron ore. Abrasive wear tests were conducted using the SSAB (Swedish Steel AB) tumbling abrasion method, which represents high-stress wet grinding conditions involving ball–ball and ball–drum collisions, as also defined in previous laboratory ball mill investigations and in more recent analyses of abrasion classification in grinding media. The results show that high-chromium cast irons exhibit the lowest wear rates (0.18 cm3/week), while low-alloy steels experience up to five times greater volumetric loss (0.91 cm3/week). Scanning electron microscopy reveals micro-grooving and matrix detachment in more complex alloys, whereas softer steels display significant corrosion-assisted pitting and cracking. These findings provide practical guidelines for alloy design and the selection of grinding media, underscoring the importance of microstructural control in tailoring materials to specific abrasive environments.","PeriodicalId":18366,"journal":{"name":"Materialwissenschaft und Werkstofftechnik","volume":"57 2","pages":"115-123"},"PeriodicalIF":1.1,"publicationDate":"2026-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/mawe.70093","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147585028","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Orthogonal test is used to determine the optimal ratio through range analysis. Additionally, using tests and characterisation techniques such flowability, x-ray diffraction, scanning electron microscopy, and thermogravimetric analysis, the study examined how the ternary early strength agents affected cement performance. The results show that the early compressive strength of cement can be improved by different proportions of experimental groups. Particularly, the combination of 2 % peanut shell ash, 0.04 % triethanolamine, and 1.25 % nano calcium carbonate exhibited optimal early strength performance. At 1 day, 3 days, and 7 days, the compressive strengths were 13.97 MPa, 26.70 MPa, and 41.91 MPa, respectively. Compared to the control group, these strengths represent increases of 91.37 %, 38.20 %, and 49.47 %, respectively. Microstructural analysis revealed that the experimental groups generated more hydration products and reduced porosity, resulting in denser cement samples. The early strength agent enhanced the production of calcium silicate hydrate gel, accelerated the cement,s hydration reaction, and raised the cement's initial strength.","PeriodicalId":18366,"journal":{"name":"Materialwissenschaft und Werkstofftechnik","volume":"57 2","pages":"134-145"},"PeriodicalIF":1.1,"publicationDate":"2026-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147615063","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Based on its application, the current study analyses the drilling performances of AISI 304 stainless steel in terms of cutting time, cutting temperature, surface roughness and surface morphology of the drilled hole surface. Spindle speed, feed rate and drill bit diameter are considered as inputs. Using Taguchi's L9 orthogonal array, 9 numbers of experiments are conducted. Analysis of variance (ANOVA) confirmed the dominant effect of spindle speed on cutting time. Similarly, spindle speed and feed rate is found significant on cutting temperature and spindle speed, feed rate and drill bit diameter on surface roughness. High spindle speed and high feed rate require less time to drill, whereas it increases the hole surface temperature. Other hand, at medium spindle speed with high feed rate, the hole surface finish is better. The coefficients of determination for cutting time, cutting temperature, and surface roughness obtained 92.2 %, 97.5 %, 96.2 %, respectively suggested more precise and reliable predictions. From morphological study, at higher spindle speeds, the surface finish of the hole surface is better than at lower spindles because of the improved grain refinement.","PeriodicalId":18366,"journal":{"name":"Materialwissenschaft und Werkstofftechnik","volume":"57 2","pages":"92-114"},"PeriodicalIF":1.1,"publicationDate":"2026-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147614945","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The grain refinement effect is observed for single time quenching from 600 °C; but not for cyclic quenching from room temperature. Lattice strain is found to be accumulated up to 2 cycles followed by a decline to a consistent lower value for 3 and 4 cycles in the specimens subjected to cyclic quenching treatment. The specimen, single time quenched from higher temperature (600 °C), exhibits much higher lattice strain as compared to all cyclic quenched specimens. The accumulation of lattice strain is found to be consistent with the evolution of regions of extremely low misorientation angle in the aluminium matrix. As a result of significantly high lattice strain generation and grain refinement effects, the hardness of commercially pure aluminium is substantially enhanced to 88 HV 10 on execution of single time liquid nitrogen quenching from 600 °C after short-duration (5 min) holding; while compared with an initial hardness of 36 HV 10 in annealed condition.","PeriodicalId":18366,"journal":{"name":"Materialwissenschaft und Werkstofftechnik","volume":"57 2","pages":"167-178"},"PeriodicalIF":1.1,"publicationDate":"2026-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147614825","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results show that the recrystallization kinetics and flow stress can be modeled in a single function of temperature-compensated strain-rate (Z) using Avrami kinetics by applying, not the conventional t1/2-method, but recently proposed ε1/2-method. Detailed analysis of the Avrami kinetics together with secondary ion mass spectrometry (SIMS) and drag force calculation show that non-equilibrium segregation of boron and boron-niobium complex occurs up to 1100 °C and its intensity increases with the strain rate. The non-equilibrium segregation decreases both the growth and nucleation rates of dynamic recrystallization by lowering the mobilities of the grain- and subgrain- boundaries. Combined addition of boron and niobium to boron-bearing carbon steels leads to more intense segregation on grain- and subgrain- boundaries, which delays the recrystallization rate more strongly at an early stage but rather accelerates it at an intermediate stage of deformation by forming iron (boron, carbon) (Fe(B, C)) aggregates.","PeriodicalId":18366,"journal":{"name":"Materialwissenschaft und Werkstofftechnik","volume":"57 2","pages":"154-166"},"PeriodicalIF":1.1,"publicationDate":"2026-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147585029","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In contrast, compressive strength and modulus decreased by 12 % and 11 %, respectively. The slide wear loss decreased with increase in high-density-polyethylene content from 55 wt. % to 70 wt. % in the composites, whereas the coefficient of friction increased as the load increased from 20 N to 60 N.
