摘    要:采用Gleeble-3500热模拟试验机,通过热压缩方法研究了锯片用65Mn钢的热变形特性。结果表明:65Mn钢在给定的试验条件下,随着应变速率的增加和变形温度的降低其变形抗力显著增加,同时峰值应变也增大。最后建立了65Mn钢的变形抗力数学模型,通过回归分析表明此模型具有较高的拟合精度。

关 键 词:65Mn钢  热变形行为  变形抗力  动态再结晶  数学模型

Abstract:The thermal deformation behavior of 65Mn steel for saw blade is investigated through thermocompression method with Gleeble-3500 thermal mechanical simulator.The results show that in a certain testing condition,the deformation resistance as well as peak strain of the 65Mn steel increases with the decrease of temperature and the increase of strain rate.A mathematical model for the 65Mn steel is established with its high fitting precision proved by regression analysis.
Keywords:65Mn steel  thermal deformation behavior  deformation resistance  dynamic recrystallization  mathematical model
