摘要
试验表明,40Cr钢在A_(C_3)点温度淬火将出现硬度峰和平缓的硬度分布。本文分析了产生硬度峰的原因,并提出A_(C_3)点温度淬火的合理性。
Experimental works showed that on the hardncss quenching temperature curve of 40 Cr steel a hardness peak apptared at the critical temperature Ac_3 with a homogeneous hardness distribution across the section of work piece, reasons are discussed.
