Optimization for Heat Treatment Process of Supercritical Material F92Steel

Abstract:

The supercritical material F92 steel is regarded as the research object, and the influence law of heat treatment process on its tissue and properties is analyzed. The results show that when the temperature of heat treatment quenching and tempering is too low, a large number of alloying elements cannot be fully integrated into the austenite, and the optimal obdurability of F92 steel is still not fully exploited; while too high temperature of heat treatment quenching and tempering will weaken the strength, plasticity and toughness. When F92 steel is processed by heating quenching at 1050 °C and tempering at 680 °C, its tissue is the smaller tempered lath martensite. The carbide is precipitated, generating precipitation strengthening, which gives it a high rupture strength and toughness. F92 steel is with high mechanical properties when heating quenched at 1050 °C and tempered 680 °C.
