By rolling and nitriding processes, 0.23- to 0.3-mm-thick grain-oriented 6.5 wt% silicon steel sheets were produced. The core losses of grain-oriented 6.5 wt% s
A two-step quenching and partitioning(Q&P) treatment was applied to low-carbon alloy steels. The relation of initial martensite- retained austenite- fresh marte
