Quench annealing
WebThis paper examines how the initial austenite grain size in quench and partitioning (Q-P) processes influences the final mechanical properties of Q-P steels. Differences in austenite grain size distribution may result, for example, from uneven heating rates of semi-finished products prior to a forging process. In order to quantify this influence, a carefully defined … WebThis video covers basic about the heat treatment of the steelIt covers an introduction about the heat treatment processes like Annealing NormalizingQuenching...
