Abstract:The effects of pack ply-rolling process on texture and mechanical properties of TA7 alloy were studied. The finished product was produced by hot-rolling instead of cold-rolling which often leads to surface crack. The results show that the pack ply-rolling process can be used to obtain the good overall properties and fine texture for TA7 alloy. At the same time, the cost of production would be reduced.
Key words: TA7 alloy sheet; pack ply-rolling; texture; mechanical property
