The microstructure and tensile properties of TIG welded joints of Al-Li alloy were investigated both in as welded and different postweld heat treatment conditions. 研究了2091Al-Li合金TIG焊焊接接头焊态及不同热处理状态下的显微组织和拉伸性能。
Corrosion-resistance aluminum, as welded structure aluminum alloy is used in industry manufacture widely. 防锈铝合金是用于焊接铝结构件的主要材料,在焊接生产中常常遇到一些困难。
The Stress Analysis of T Shape Multi as welded Joints Weld Bead T型接头多次补焊焊缝的应力分析
A kind of hardfacing alloys were developed for impact wear-resistant which is a Fe-Mn-Cr-Mo-V alloy system. After impact experiment the hardness degree of deposited metal increases 66 % compare with the hardness degree of deposited metal as welded. 成功研制了一种适用于抗冲击磨料磨损条件下的堆焊合金,合金系统为Fe-Mn-Cr-Mo-V,在受到较大载荷冲击后较焊态堆焊层硬度提高66%。
The tests results show that the microstructure of the welding line under the as welded condition is typical coarse spiculate martensite and retained austenite; 试验结果表明,该钢电子束焊接接头焊缝为典型的粗大针状马氏体加残余奥氏体组织,HAZ(热影响区)为中温组织;
