Study on Effect of Hot Extrusion on Microstructure and Properties of Be-Al Alloy AITranslate
Abstract AITranslate
In order to shorten the forming time of powder metallurgy,Be-Al alloy was subjected to hot extrusion after cold isostatic pressing,and the effect of hot extrusion on the microstructure and properties of Be-Al alloy was studied.The results show that after hot extrusion deformation,the beryllium phase of Be-Al alloy distributes in continuous aluminium phase in granular form,the microstructure is compact,and the density of material significantly increases.At the same time,the hardness of Be-Al alloy after hot extrusion increases to 80 HRB,accompanied by larger internal stress.The grain orientation of beryllium and aluminium phases after cold isostatic pressing is relatively random.After hot extrusion,beryllium phase has no obvious preferential orientation,and aluminum phase mainly forms the fiber texture with strong 〈100〉 orientation and weak 〈110〉 orientation.
