Achieving excellent strength-ductility synergy in (Co, Cr)58Ni30Mo6Al6 high entropy alloys by suppressing intermetallic compounds and introducing nanoprecipitates

Journal of Materials Research and Technology
Precipitation hardening serves as a viable mechanism to enhance the strength of high/medium entropy alloys (H/MEAs). The nature of precipitates in HEAs varies based on the composition of multiple principal elements.

On coherent carbonitride precipitation in commercial microalloyed steels

Philosophical Magazine Letters, 2003
Fine vanadium carbonitride particles nucleated during interphase precipitation have been investigated in the transmission electron microscope under controlled conditions of diffraction contrast. On dark-field micrographs taken with a carbonitride reflection, particle sizes ranged from 5 nm down to below 2 nm in diameter.
