Abstract: Two distinct heat treatments, that is, intercritical quenching combined with low‐temperature tempering (QT) to control the initial quenching temperature, and salt‐bath quenching combined with partitioning (Q&P) to regulate the final quenching temperature, were employed on… read more here.

Abstract: Abstract The yield ratio of investigated steel decreased significantly from 0.93 to 0.59 by prolonging intercritical annealing duration to weak multi-strengthening effects. The contribution of each effect was qualified by theoretical calculation. The grain refinement… read more here.
