The numerical simulation of the brazing process of cemented carbide cirque and steel;
硬质合金圆环与钢基体钎焊过程的数值模拟
Aiming at the brazing crack induced by the thermal stress during the process of brazing, this paper analyses the residual stress of joint between the cemented carbide cirque and steel matrix by using MARC software, and researches the effect of the filler metal thickness and the applied load on the magnitude and distribution of the residual stress.
针对硬质合金钎焊冷却过程中产生很大的热应力而导致裂纹这一问题,利用有限元软 件MARC对硬质合金圆环钎焊在钢基体上的残余应力大小及分布进行了模拟,研究了钎缝厚度、 钎焊压力对钎焊焊后残余应力大小及分布规律的影响。
To large area cemented carbide cirque, it i.
但由于这些材料塑性、韧性、抗冲击性都较差,在与其他材料钎焊冷却过程中常会因材料的性能参数的不匹配而使接头处产生相当大的残余应力变形甚至产生裂纹,对于大面积硬质合金圆环,钎焊过程中更容易出现裂纹或开裂。
