用x射线定量法及物理化学相分析法对GCr15钢残余奥氏体、马氏体、碳化物进行测定的结果表明,喷吹后钢中残余奥氏体、固溶碳含量、碳化物的含量均有所增加。这是导致喷吹工艺的GCr15钢强度、断裂韧性以及接触疲劳强度提高的重要原因。
The determination of residual austenite, martensite and carbides in GCr15 steel by X-ray quantitative analysis and physical-chemical phase analysis showed that residual austenite, dissolved carbon content and carbide content Have increased. This is an important reason for the strength, fracture toughness and contact fatigue strength of the GCr15 steel during the blowing process.
