Achieving superior mechanical property and large adjustability in a metalloid-free FeCrNi alloy

Zhicheng Miao, Dongmei Zhang, Beibei Jiang, Zhaowen Huang et autres

Advanced structural alloys with high performance and large property adjustability are desired for engineering applications. However, traditional multi-micro-alloying metallurgy depends on the specific manufacturing technique, leading to the narrow processing window, poor welding ability and structural stability. In this proof-of-concept study, a …

Multi-directional deformation for coordinating isotropy and strength-ductility synergy in a CoCrNi alloy

Na Lin, Zhicheng Miao, Mingcan Li, Rumeng Huang et autres

Due to the intrinsic lattice symmetry, anisotropy always exists in metallic materials, and it will be further enhanced or reduced to a certain degree during the subsequent processing, leading to the directional strength-ductility modulation. To meet the high-performance requirements for complicated servicing …
