Fabrication of hierarchical layered structure in Zr/Ti composite via multi-step heat treatments and its effect on the mechanical properties

Autor: Jiateng Ma, Xinu Tan, Junjie Li, Weijun He

Publikováno v: Journal of Materials Research and Technology, Vol 33, Iss , Pp 3080-3092 (2024)

The strength and ductility of metallic structural materials are two pivotal properties generally considered mutually contradictory. In the past few decades, numerous heterogeneous materials have been designed and fabricated to overcome this trade-off

Superior strain-hardening and strength-ductility synergy by hierarchical L12 phases in a highly (Al, Ti)-added medium-entropy alloy

Autor: Shiyu Du, Tuanwei Zhang, Jinyao Ma, Zhiming Jiao, Jianjun Wang, Shengguo Ma, Renlong Xiong, Zhihua Wang

Publikováno v: Journal of Materials Research and Technology, Vol 33, Iss , Pp 2856-2867 (2024)

A novel precipitate-strengthened Co–Cr–Ni medium-entropy alloy with a pure “FCC + L12” dual-phase structure is developed by adding a high concentration (6 at.%) of Al and Ti elements. After aging heat treatment at 700 °C for 4 h, the hierarc
