摘要
研究了新型贝氏体钢钎头材料的组织、力学性能及耐磨性能,结果表明,新型贝氏体钢钎头材料组织由贝氏体铁素体(BF)和奥氏体(AR)组成,具有良好的强韧性、耐磨性和较高的回火抗力。能够用于制造钎头材料。
The microstructure, mechanical properties and wear resistance of new type bainite steel were studied. The results show that the microstructure of new type bainite steel bore bit is bainite ferrite (BF) and retained austenite and has good strength-toughness, wear resistance and has higher tempering resistance. It can be used for bore bit materials.
