Effect of intercritical annealing temperature on equilibrium between ferrite and austenite

Materials Science and Engineering, 1987
Abstract The martensite content of the dual phase Fe-1.0%Mn-0.5%Cr-0.5%Si-0.2%C steel intercritically annealed for 20 min at temperatures up to 770 °C was the same as that calculated by partial equilibrium. This implies that partitioning of carbon occurs and not partitioning of substitutional solutes.

Formation of austenite from a ferrite-pearlite microstructure during intercritical annealing

Journal of Materials Science, 1985
The formation of austenite from a coarse grained ferrite-pearlite microstructure during intercritical annealing was studied. According to the variation of the microhardness values in ferrite and austenite with intercritical annealing time, austenite formation was classified into four stages: (a) austenite growth into pearlite at a slower rate than the ...

Effect of Intercritical Annealing Temperature on Martensite Amount for Dual-Phases Steel

Advanced Materials Research, 2012
The theoretical prediction of intercritical annealing temperature for DP steels was conducted by thermodynamic calculation, which agreed to the experimental results. When annealed at 800°Caccording to the calculated temperature of 807°C by setting ratios of α:γ in 70:30, the amount of martensite was 13~18% and the mechanical properties achieved DP590 ...
