Dislocation Density of Lath Martensite in 10Cr-5W Heat-Resistant Steels

Abstract

Dislocation densities in 10Cr-5W low-carbon steel that containing carbon content is 0.02C, 0.03C, 0.09C and 0.13C mass% were determinedd from X-ray line analysis based on the modified Williamson-Hall and Warren-Averbach methods. In the as-quenched state the dislocation density in the martensite phase increased with increasing carbon content for these low-carbon steels.
