Abstract
This study investigated the effect of deep cryogenic treatment (DCT) duration on the microstructure, hardness, and wear resistance of two experimental H13 hot‐work die steels with different chemical compositions. The steels were quenched, subjected to DCT at –196 °C for 10, 20, and 30 h, and subsequently double tempered. The microstructure was characterized by EBSD, SEM, XRD, and EDS, while the hardness and wear behavior were evaluated by Vickers hardness and dry sliding wear tests. With increasing DCT duration, Steel B exhibited a pronounced microstructural response, resulting in a decrease in retained austenite from 13.7% to 3.5%, an increase in hardness from 310.3 to 343.1 HV, and a reduction in wear loss from 12.9 to 5.7 mg. In contrast, Steel A showed only slight changes in microstructure, hardness, and wear behavior. These results demonstrate that the response of hot‐work die steels to DCT is governed by the combined effects of chemical composition and initial microstructure, providing guidance for optimizing cryogenic treatment to improve wear resistance.
Abstract In this study, in order to examine the impact of heat treatment (diffusion annealing) on the microstructure, hardness, wear, and corrosion behavior, electrogalvanized DC01 steel was diffusion-annealed at 500, 550, and 600 °C. While hardness, tribological, and corrosion properties were assessed using microhardn...
Introduction. Austenitic steels are widely used in mining, railway, and chemical industries due to their high toughness and corrosion resistance. However, their service life under severe wear conditions is limited, which necessitates the development of effective surface hardening techniques that preserve the ductility...

This study investigates the effect of molybdenum (Mo) content on the microstructure, hardness, and wear resistance of ASTM A532 eutectic high-chromium white cast iron (HCCI) subjected to destabilization heat treatment with different cooling paths. Three alloys containing 1.23%, 1.395%, and 1.86% Mo were destabilized...

In this research, AZ91 magnesium alloy was subjected to solutionizing at 410 °C for different soaking times (4, 8, 16, and 24 h), and the microstructure evolution, phase change, and mechanical and corrosion properties were investigated. From the microstructural studies, it was clearly observed that the intermetallic ph...

This study investigated the effects of Hot Isostatic Pressing (HIP) and gas nitriding on the microstructure, hardness, and tribological behavior of Ti6Al4V alloy fabricated by Electron Beam Melting (EBM). As-built specimens exhibited a lamellar α + β microstructure governed by the EBM thermal history. HIP treatment c...
