Abstract : the article analyzes the influence of failure of heat treatment process and equipment for mn13 steel join , and offeres the method of preventing the part slitting and brittle cracking 文摘:分析了热处理工艺和设备对高锰钢端头缺陷的影响,提出了防止高锰钢端头脆性开裂的措施。
: 36 < kth < 37 mpa / m3 / 2 , 42 < kih < 44mpa / m3 / 2 , 51 < kc < 52 mpa / m3 / 2 through the sem fractography , it is know that the susceptibility to brittle failure at room temperature is more than below 100 ? . and the susceptibility to brittle failure increase with hydrogen increasing , under the sustained loading , ductile cracking appears . the quantity of brittle cracking is more with crack growth T44mpa m ‘ q , sl lt52mpa in ’ ”断口分析表明,该合金充氢后其室温时的氢脆敏感性大于100oc时的氢脆敏感性;且随氢含量升高,氢脆敏感性增加:在恒载荷的作用下,该合金裂二纹开始扩展时显示的是韧性起裂;随裂纹增长,试样脆性断裂的比例增大。
The electrical cut scanning mirror shows : this bilinear behavior results from different cracking ways under high and low strain amplitudes , that is , elastic cracking and brittle cracking respectively . cyclic hysteresis energy is an important fatigue parameter . the total cyclic hysteresis energy of gh4145 / sq increases gradually as strain amplitude goes from 1 % to 0 . 5 % , but it decreases when strain amplitude is lower than 0 . 5 % 在高温低周疲劳下, gh4145 / sq合金的循环滞?能具有如下特征:在1 0 . 5应变幅范围内,循环总滞?能是一个逐渐增大的过程,而当应变幅小于0 . 5时,总滞?能随应变幅减小而趋于减小;半寿命处的循环滞迥能和总滞?能与寿命之间的关系曲线表现出双线性特征,转折点对应0 . 5应变幅。
