Effect of the thermomechanical treatment on the microstructures of CLAM steel

Abstract

Abstract-The thermomechanical treatment test of CLAM steel is simulated by the thermal simulated test machine Gleeble3500, by means of constant temperature compression test to study the effect of the thermomechanical treatment processing on microstructure of China Low Activation Martensitic steel(CLAM steel). The results show that the thermomechanical treatment processing has a great effect on the microstructure of CLAM steel, which makes a great contribution to refine the martensitic lath, the formation of M 23 C 6 carbide and MX nano-sized carbo-nitride, leading to strengthen the CLAM steel's structure. Thus by means of the thermomechanical treatment processing to refine the microstructure of CLAM steel to improve its property is viable.
