Effect of Solution Annealing on the Microstructure and Mechanical Properties of Modified 440A Martensitic Stainless Steel

This study was investigated the effect of austenitizing treatment the microstructure and mechanical properties in modified 440A steel, and the results were as follows. The amount of remaining carbide decreases with increasing the austenitizing treatment temperature, and all carbide is completely dissolved at 1250^{\circ}C/TEX>. The amount of remaining carbide decreases with increasing the austenitizing treatment time, but the carbide...
