01420铝锂合金焊缝金属的金相特征
Metallographic Feature of 01420 Al-Li Alloy Welded Seam
【摘要】 研究了01420合金焊缝金属析出相的分布规律、结晶类型及晶粒度之间的内在联系,通过人工时效处理,使该合金焊缝金属在保持焊后态晶粒度不变的前提下,经腐蚀后显现晶界.
【Abstract】 This research is mainly on the interrelation of precipitated phase,type of crystallization and grain size in fusion zone of 01420 alloy. By artificial ageing,the grain boundaries could be appeared while the grain size is kept unchanged.
