The effects of load on the microstructure and wear behavior of Co–27Cr–22Fe alloy processed by high-temperature nitriding

Journal of Materials Research and Technology, 2023
In this study, high-temperature nitriding was used to improve the surface hardness and wear resistance of Co–27Cr–22Fe alloy in a thermogravimetric analyzer. The high-temperature nitriding treatments were performed at 1200 °C for 3 and 10 h. Subsequently,

Breaking through the strength-ductility trade-off of LPBF-produced Ti-xNb alloys from mixed powders via ω-phase induced heterostructure

International Journal of Extreme Manufacturing
Ti- x Nb alloys produced by laser powder bed fusion (LPBF) from mixed powder usually exhibit an inhomogeneous elemental distribution, leading to a deterioration in mechanical properties.
