【摘要】 根据导向板的工况条件和失效形式,合理选取原材料、严格控制熔炼工艺和热处理工艺,最终获得ADI导向板的力学性能为:洛氏硬度≥41 HRC,抗拉强度>1 300 MPa,伸长率>3%。该导向板的使用寿命是同等工况下高频表面淬火铸钢的3倍左右。更多还原

【Abstract】 Based on the working conditions of the guiding plate and its failure type and by choosing appropriate raw materials,strictly controlling melting and heat treating processes,the ADI guiding plate with following mechanical properties was finally obtained: hardness≥41 HRC,tensile strength>1 300 MPa,elongation>3%.The working life of such guiding plate was about 3 times of the working life of the high frequency surface quenched cast steel guiding plate under the same conditions.更多还原
