The presence of oxide particles significantly reduces the tensile strength of powder bed fusion-ed (PBF-ed) H13 steel. The size and distribution of the oxides depend on the selection of both PBF and heat treatment parameters. The purpose of this paper is to maximize the tensile strength of PBF-ed H13, making it comparable to conventional forged and heat treated H13.The research was conducted in two steps. First, PBF processing parameters of laser power, laser speed, hatching space, printing strategy, and preheating temperature were optimized to minimize manufacturing defects and maximize mechanical strength. In the second step, tailored heat treatments were investigated, including annealing at 500 °C for 2 h, quenching at 1020 °C for 1 h, and double tempering at 550 °C for 2 h. Experimental results show that annealing at 500 °C effectively reduces residual stress but does not achieve sufficient elongation. The combination of quenching and tempering significantly enhances elongation to 15% while maintaining a tensile strength of approximately 1517 MPa. This optimized heat treatment strategy also minimized the size and distribution of oxide particles, keeping them under 6 μm in diameter, thereby reducing their detrimental impact on mechanical properties.</p><h3>Graphical Abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":703,"journal":{"name":"Metals and Materials International","volume":"31 5","pages":"1286 - 1312"},"PeriodicalIF":3.3,"publicationDate":"2024-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143875399","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this review article, the effects of various alloying elements of Inconel 718 like Fe, Cr, Al, Ti, Nb, Mo, Co, B, and C, and the relevant phases formed are discussed in context to the various heat treatments applied to the alloy. Heat treatments such as homogenization and age hardening applied to nickel-based superalloys in general and also specifically to Inconel 718 are reviewed in detail with respect to the processing routes employed, i.e., casting, wrought metallurgy, powder metallurgy and additive manufacturing. Some of the simulation techniques like the Scheil module in Thermo-Calc and DICTRA which are used for predicting the homogenization time and temperature are also discussed. The metallurgical aspects of nickel-based superalloys deal with their composition and property relationships, microstructure evolution, and various strengthening phases formed during heat treatments. The various precipitate phases of Inconel 718 i.e., γ′, γ′′ and δ formed during the processing and heat treatments, and their contribution to the enhancement of high temperature and room temperature mechanical properties are also elucidated in detail. The effect of precipitate volume fraction, morphology, and size on the enhancement of high-temperature and room-temperature mechanical properties is reviewed in particular as per recently published reports in this field.</p><h3>Graphical Abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":703,"journal":{"name":"Metals and Materials International","volume":"31 5","pages":"1204 - 1231"},"PeriodicalIF":3.3,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143875289","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mg-Al spinel inclusions, which are known for their high deformability, are particularly detrimental. Thus, controlling these favorable liquidus inclusions, such as Ca-Al inclusions, is crucial. The evolution of Ca-Al inclusions is primarily driven by the [Ca] source in molten steel, which is supplied by slag or the addition of Ca to the molten steel. Inclusions exhibit three physical behaviors: flotation into the slag, entrapment from the slag, and agglomeration within each inclusion. A numerical model grounded in a coupled reaction model was established to investigate these inclusion behaviors, with a focus on the evolution of the Ca-Al system inclusions. These findings indicate that the [Ca] concentration in molten steel drives the evolution of Ca-Al inclusions, but the rate of evolution is limited by the mass transfer rate of the Ca source into the inclusion. Moreover, slag composition, particularly the higher basicity and slags enriched with Ca sources, such as CaF<sub>2</sub>, significantly influence the inclusion composition, reaching a composition closer to the liquid phase. Additionally, it was found that the physical behavior of inclusions, particularly entrapment from slag, plays a crucial role in controlling the inclusion composition.

However, these gears are subjected to a long ageing process during ion nitriding, resulting in remarkable variations in the austenite volume fraction (<i>V</i><sub>a</sub>), which strongly affects the dimensional accuracy of the product. Therefore, accurately predicting <i>V</i><sub>a</sub> is crucial for optimizing the chemical heat treatment process of CF170 steel. In this work, the nonisothermal and isothermal ageing process, combined with Kissinger analysis and the Johnson‒Mehl‒Avrami (JMA) model, proved that the nonisothermal kinetic model was applicable for the prediction of <i>V</i><sub>a</sub>. Moreover, models of the preexponential factor <i>K</i><sub>0</sub> and maximum austenite volume fraction (<i>V</i><sub>max</sub>) were proposed, and a kinetic model of austenite phase transformation after ageing at 482–593 °C for 0–6000 min was established, which predicted and controlled the microstructure within a large temperature and time range. The nucleation mechanism of austenite in CF170 steel was investigated by scanning electron microscopy (SEM), electron backscattering diffraction (EBSD), and transmission electron microscopy (TEM). Nucleation was regulated by a shear mechanism, with nucleation occurring primarily at the grain boundary, packet, block, and subblock interfaces. The nucleation was the reversion of γ → α → γ, and the austenite inherited the crystal orientation features of the prior austenite, demonstrating the “austenite memory” phenomenon.</p><h3>Graphical Abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":703,"journal":{"name":"Metals and Materials International","volume":"31 5","pages":"1254 - 1271"},"PeriodicalIF":3.3,"publicationDate":"2024-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143875327","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To simulate actual plant conditions, the surfaces of specimens were pre-treated with heavy grinding. Specimens processed a single time and multiple times (× 2, × 4, and × 8) were prepared to evaluate the impact of repeated treatments. The results indicated that all techniques achieved a compressive residual stress field of at least 1 mm depth, as intended. UNSM generated the highest compressive residual stress on the surface, followed by ULP, WJP, and ALP. UNSM also introduced the deepest layer of plastic deformation and grain refinement. ULP initially showed dislocations after a single treatment, while grain refinement occurred after two treatments. WJP and ALP introduced the thinnest layers of plastic deformation, but the smallest grains were observed near the surface. Increasing treatment number deepened plastic deformation but had limited effect on increasing surface residual stress, with only ALP showing a continuous increase.
