钨钼高速钢中奥氏体的热稳定化和失稳——1984,8,28～31[俄]本文研究了稳定化因素——在20℃长时间保持并在100～400℃回火,对比了冷处理并高温回火P6M5和P6M5K5淬火钢中奥氏体转变的影响。确认了弹性应力松弛和奥氏体稳定化与马氏体转变的关系。在300～400℃回火并在20℃保温2个月,奥氏
Thermal Stability and Instability of Austenite in Tungsten-Molybdenum High-Speed Steel - 1984, 8, 28-31 [J] .This paper studied the stabilization factors, which were kept at 20 ℃ for long time and tempered at 100-400 ℃, The effects of cold treatment and high temperature tempering on austenite transformation in P6M5 and P6M5K5 hardened steels were compared. The relationship between relaxation of elastic stress and austenite stabilization and martensitic transformation was confirmed. Tempering at 300 ~ 400 ℃ and incubated at 20 ℃ for 2 months, austenitic
