Feb 02, 2013· detailed evaluation of Q&P processing in the case of High-Si steel, the study was restricted to roughly determine appropriate rolling conditions for High-Al steel and hence, specimens were partitioned for 10 - 1000 s only at the quench stop temperature, i.e., T P = T Q giving initial martensite fractions of about 70-90%. Figure 1.
