By using Optical microscope, Scanning Electron Microscope and Microhardness testing an investigation has teen made about the failure behavior of hot-roller forging die used for thermo-forming 2Cr13 stainless steel table knife. It could be observed that during service on the working surface of the die there appear two kinds of surface damages: Roughening by picking and subsidence resulting from high temperature fatigue and checking cracking from thermalfatigue. These two are quite different not only in the appearance but also in their induced cracking propogation direction. Analysis indicated that in our case the contact fatigue damage is the main reason causing premature failure of the die. Hence it can be considered that to raise the strength and plastic deformation resistance of its surface layer at elevated temperature is thekey for increasing the service life of dies. Our experimental results have shown that the service life of this die can be significantly improved by using appropriate thermo-chemical treatment.

本文运用金相分析、扫描电镜和显微硬度等方法对不锈钢餐刀热辊锻模具的失效特征进行了分析。观察发现:该模具在服役过程中工作表面上出现二种不同的表面损伤:即因高温接触疲劳引起的拉毛和塌陷以及因热疲劳引起的龟裂。二者不仅形貌不同且它们在纵断面上诱发的裂纹走向也各异。分析表明,造成该模具早期失效的主要原因是由于接触疲劳引起的表面损伤。由此可认为:提高模具表面层的热强性及塑性形变抗力是提高该辊锻模寿命的关键。本试验结果证实了采用合适的化学热处理确能显著提高3Cr2W8V热辊锻模的使用寿命。
