摘要
研究了经碳氮共渗处理后40Cr钢的抗弯性能与共渗层特征参数和试样尺寸大小之间的关系,借助多元回归分析方法,找出了抗弯性能指标与共渗层厚度、硬度梯度、表面硬度、心部硬度、δ/D、L/D等参数之间确定的函数关系式,并进行了分析和探讨.
This paper deals with relations between bending property of 40Cr steel carbonitrided and case characteristic parameters and specimen dimensions. By means of multi-factor regression analysis, some definite functional relationships have been found between bending property and independent variables such as case depth, hardness gradient, surface handness, core hardness, δ/D (case depth/sample diameter), L/D (sample gauge length/sample diameter)etc.
