【摘要】 本文利用ＣｒＷＭｎ钢刀片镶钢余热进行高温淬火，有效地抑制网状碳化物的析出。以高温回火代替球化退火，实现碳化物超细化。降低淬火加热温度．获得细小奥氏体晶粒。使ＣｒＷＭｎ镶钢刀片的抗弯强度与冲击韧性由δ-bb=1088MPa,α-k=19.6J/cm～2提高到δ-bb＞2466MPa,α-k＞88J/cm～2,HRC＞60，获得明显的强化韧化效果．更多还原

【Abstract】 Using the weld remaining heat the high temperature quench is carried out for the blade of CrWMn steel to restraing the net carbonide. High temperature temper is carried out for fining the carbonide. The Austenization temperature is reduced for fining the Austenite grain The properties of the CrWMn Steel are improved from δ-bb 1088MPa, α-k19.6J/cm～2 to δ-bb 2466MPa, α-k88J/cm～2, HRC>60.更多还原
