腐蚀疲劳裂纹,corrosion fatigue crack
1)corrosion fatigue crack腐蚀疲劳裂纹
1.The microanalysis results show that the inclusions in weld metals, welding residual stress, working stress,mechanical vibrating stress and electrochemical corrosion of metal caused the penetrationcorrosion fatigue cracks in weld metals and its heat affect zones of hydraulic turbine blades.水轮机叶片上的焊缝及其热影响区常发现有穿透性的裂纹,微观分析结果表明焊缝中存在夹杂物,在焊接残余应力、工作应力、机械震动应力和电化学腐蚀的共同作用下,造成水轮机叶片的焊缝及其热影响区形成穿透性的腐蚀疲劳裂纹。
2.Under fatigue load and corrosion medium,corrosion fatigue crack appeared first at the bottom of thread which was the dangerous section part of the pin joint.结果表明:加重钻杆断裂属于腐蚀疲劳断裂;断裂主要原因是加重钻杆接头内径大于标准规定值,降低了加重钻杆外螺纹接头断裂扭矩和抗拉载荷,在疲劳载荷与腐蚀介质作用下,腐蚀疲劳裂纹首先在加重钻杆外螺纹接头危险截面部位螺纹牙底萌生,随后在载荷作用下裂纹不断扩展,进一步降低了接头的强度,最终发生了断裂事故。

疲劳裂纹生长分子式：CAS号：性质：材料在连续交变应力作用下，会在其表面逐渐生成裂纹，并随着作用时间而逐渐向纵深发展，使裂纹扩展，试件的力学性能下降，最终导致完全断裂。应该指出，有些材料耐初始裂纹生长的性能很好，但一旦生成却发展很快。而另一些材料就正好相反。所以对疲劳裂纹的生成和发展是疲劳试验中最关心的性状之一。
