The results indicates that the majority of the compounds in molten zone were produced to be τ5(Zr38Cu36Al26),those in the HAZ were ZrCu with small amount of τ5 when the welding speed was 2 m/min,and the compounds existed in HAZ and the molten zone kept amorphous,while the welding speed was 4 m/min,and the formation of any crystalline phases was not detected at the interface,Whe.
采用传统激光焊接技术连接块体非晶合金Zr45Cu48Al7,试验结果显示:焊接速率为2m/min时,熔化区主要生成τ5(Zr38Cu36Al26)相,热影响区主要生成ZrCu相,含有少量τ5相;焊接速率为4m/min时,熔化区保持了非晶特性,热影响区有晶粒生成;当焊接速率8m/min时,热影响区和熔化区均保持非晶特性。

结果表明:在焊接热循环作用下,熔化区和热影响区的晶粒形貌和组织具有很大的差异;焊接速率为2 m/min时,熔化区主要生成5τ(Zr38Cu36Al26)、ZrCu和一未知相,热影响区主要生成ZrCu相;焊接速率为4 m/min时,熔化区保持了非晶特性,热影响区部分晶化,其主要生成相为ZrCu相;热影响区的晶化行为与非晶合金热处理过程的晶化行为有一定的区别,其主要原因是激光焊接时的高速加热及冷却过程对各晶化相生长速率影响程度不同。
