B2-Intermetallic Phase Characterization in a Ferritic Fe-Cr-Ni-Mn-Al-C Steel

摘要：

　　The unexpected increase in the apparent coefficient of thermal expansion (CTEa) of a ferritic Fe–Cr–Ni–Al–Mn–C stainless steel was investigated.This anomaly was ascribed to the dissolution of fine (Ni,Fe)Al precipitates with B2 crystal structure upon continuous heating.The increase in the CTEa during the dissolution of B2 precipitates was attributed to the lattice expansion of the ferritic matrix.Accordingly,the end of B2 dissolution was associated with a decrease in the CTEa.This was confirmed by microstructure examination of samples quenched from different temperatures.
