Effect of Precursor Microstructure on Retained Austenite and Mechanical Property of Low Carbon Steels with IQ&P Treatments

Cailiao gongcheng, 2017
The microstructure, retained austenite and mechanical property of low-carbon steels with different precursor microstructures were studied by means of intercritical reheating-quenching and partitioning (IQ&P) processes. The results show that the structure

Structurally Complex Precipitates Enhance Strength‐Ductility Synergy in a Duplex Medium Entropy Alloy

Advanced Science, EarlyView.
Strong‐yet‐ductile precipitation‐hardening alloys require novel microstructural complexity of precipitates in particularly at cryogenic condition, to constantly impart strain hardening of hard‐and‐brittle precipitates. The present work creates innovative structurally complex precipitates assembled with dispersed nanocores and a chemical‐heterogeneity ...
