主 题：Heterogeneous microstructure Phase transformation Retained austenite Quenching temperature Chemical patterning
摘 要：Chemical heterogeneity in high-temperature austenite is an effective way to tune the austenite-to-martensite transformation during *** effect of quenching temperature on microstructure evolution is investigated when the high-temperature austenite is *** fast austenitization from partitioned pearlite consisting of Mn-enriched cementite and Mn-depleted ferrite in Fe-0.29C-3.76Mn-1.50Si(wt.%)steel,quenching to room temperature and quenching to 130℃ followed by 400℃ partitioning are both *** increasing quenching temperature from 25 to 130℃,the amount of heterogeneous microstructure(lamellar ghost pearlite)increases from 10.6%to 33.6% and the thickness of Mn-enriched retained austenite film is increased from 31.9±5.9 to 51.5±4.4 nm,indicating an enhancement of chemical *** is probably ascribed to the reduction in driving force for austenite-to-martensite transformation,which requires a lower Mn content for austenite retention.
