摘要
用25t压力机在1000℃对A3钢进行不同变形量、润滑方法,预热状态等对钢的热塑性摩擦系数(μ)影响的研究。在相同的变形量和150℃预热条件下,对比3Cr2W8V,4Cr3Mo2MnVB、4Cr3Mo2MnSiVNbB、4Cr5Mo2MnVSi、3Cr3Mo3VNb、4Cr5MoSiV 6种热作模具钢的热塑性摩擦系数,以及润滑对热塑性摩擦系数的影响。同时还研究了6种热作模具钢在1000℃时的高温强度、延伸率、抗氧化性能与热塑性摩擦系数的关系。
The influence of the coefficient of hot plastic friction of A3 steel on the deformation amount, lubrication method and preheating is studied with 25 tons punch at 1000℃. The coefficients of hot plastic friction of 3Cr2WSV, 4Cr3Mo2MnVB, 4Cr3Mo2MnSiVNbB, 4Cr5Mo2MnVSi, 3Cr3Mo3VNb and 4 Cr 5 MoSiV steels and the influence of lubrication on the coefficients of hot plastic friction are compared at the same deformation amount at the preheating temperature of 150℃. The relations between coefficient of the hot plastic friction and the high temperature strength, pecentage elongation and resistance to oxidation of the six types of hot work die steels are studied at 1000℃. The results give a good guide to study and selecting steel in factory
