In this work, four titanium alloys with varying initial structures were obtained by adjusting the V content: Ti-xV-5Zr–3Al–2Cr (x = 9,12,13,15 wt.%) (TxV). The influence of stress-induced α\" martensite transformation (SIMα\") on the mechanical properties of alloys was systematically investigated. The T9V alloy, despite its high content of α′ martensite, showed a total elongation of 27.7 %, attributed to SIMα\" alleviating stress concentration. In the T12V and T13V alloys, SIMα\" initially occurred, followed by the formation of {332} &lt;113&gt; twins within α\" martensite, which enhanced the uniform deformation ability, resulting in total elongation reached 44.7 % and 50.1 %, respectively. Concurrently, the reduction in the mean free path of dislocations and the reorientation of α\" martensite improved work-hardening ability. Notably, the existence of kind bands endowed the T12V alloy with a superior work-hardening rate (14.1 GPa). In contrast, the T15V alloy, which lacked SIMα\" during deformation, resulting in a lower total elongation of 19.0 %.</div></div>","PeriodicalId":54332,"journal":{"name":"Journal of Materials Research and Technology-Jmr&t","volume":"36 ","pages":"Pages 736-750"},"PeriodicalIF":6.2,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143680396","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Several inks and fillers have been used as the main components of scaffolds. This study develops scaffolds based on polycaprolactone (PCL), as printing ink, and different contents of tetracalcium phosphate nanoparticles (N-TTCP) (10–40 wt%), as a calcium-releasing source and antibacterial agent. Scanning electron microscopy and mercury porosimetry were used to investigate morphology and porosity of the scaffolds. The results showed the PCL/N-TTCP scaffolds possessed controllable porosity, in the range of 35–62 %, in which adding N-TTCP decreased the pore volume and size, in a concentration-dependent manner. Moreover, incorporating N-TTCP increased biodegradation of the PCL scaffold and improved its hydrophilicity. The compressive strength of pure PCL scaffold with the strand thickness of 355 μm was about 19 MPa. It reached to about 40 MPa by adding 40 wt% N-TTCP, with the strand thickness of 470 μm. The antibacterial activity of the pure PCL scaffold against staphylococcus aureus was 6.6 %, which increased to 58.6 % for the nanocomposite scaffold containing 40 wt % tetracalcium phosphate nanoparticles. The results of cell studies demonstrated that tetracalcium phosphate nanoparticles acted as a calcium releasing source and promoted adhesion, proliferation and ALP activity of MC3T3-E1 cells on the scaffold surfaces. Additionally, the PCL/N-TTCP scaffolds induced a higher level of bone metastasis-related proteins than the pure PCL scaffolds. Overall, the findings suggest that 3D-printed PCL/N-TTCP nanocomposite scaffold is an appropriate candidate for bone tissue engineering; however, complementary in-vivo and human clinical studies are expected.</div></div>","PeriodicalId":54332,"journal":{"name":"Journal of Materials Research and Technology-Jmr&t","volume":"36 ","pages":"Pages 1130-1145"},"PeriodicalIF":6.2,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143680465","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This work aims to investigate the initial mechanism of residual stress generation through the subsurface deformation information within the machined and unmachined subsurface zones using the in-situ digital image correlation (DIC) technique. A high-speed in-situ measurement system was developed to obtain high-resolution microscopic images within the cutting zones. Meanwhile, a new Drop Hammer based Orthogonal Cutting (DHOC) testing machine was designed to achieve orthogonal cutting with continuous cutting speed change. Displacement and shear strain fields were obtained to identify the material flow characteristics within the subsurface zones. The effect of subsurface deformation caused by serrated chip formation on the generation of residual stress was revealed. The initiation of residual stress development was determined based on the subsurface deformation state during the cutting process.

A continuous nitrogen-increase experiment was conducted in molten steel, supported by thermodynamic calculations and scanning electron microscopy-energy dispersive spectroscopy (SEM-EDS), optical microscopy (OM), high-temperature confocal laser scanning microscopy (HT- CLSM) and electron probe microanalysis (EPMA). The results show that the nitrogen content in the steel rises with prolonged nitrogen blowing, reaching saturation after approximately 35 min. SEM-EDS revealed the mechanism of complex nitride inclusions in steel gradually complicated with the increase of nitrogen content. These progress from almost no nitrides (0.0064 % N) to combinations such as TiN, BN, and TiN-BN (0.0128 % N), and further to complex inclusions including TiN–Al₂O₃ and BN-Al₂O₃ (0.0232 % N), eventually reaching Al₂O₃-TiN-BN (0.0386 % N). Thermodynamic calculations reveal a sequential formation of nitrides: TiN→BN→AlN. The maximum quantity of nitrides increases with nitrogen content, and the revelation of the mechanism by which BN inhibits formation of AlN through thermodynamic calculations combined with in situ observations. BN and AlN formation involve nitrogen extraction from TiN, reducing the quantity of TiN. Additionally, the lattice mismatch calculation and EPMA show that the three nitrides can significantly promote austenite grain refinement during heat preservation. This behavior pins austenite grains, refining their size. Nitrogen solubility in this system ranges from 0.0400 % to 0.0451 %, with the optimal nitrogen addition recommended to stay below 0.02 %.
