بررسی ریزساختار، سختی و ترکیبات بین فلزی جوشکاری اصطکاکی اغتشاشی ۱۰۵۰ Al و مس

In this research, friction stir welding of aluminum ۱۰۵۰ to copper with variable speed was investigated. For friction stir welding, rotational speeds of ۹۰۰ and ۱۲۰۰ rpm and traverse speeds of ۳۶, ۶۳, and ۱۲۵ mm/min were used. In order to check the phases and microstructure, scanning electron microscope analysis, X-ray spectrometry, and hardness testing were used. The disturbance zone included Al۲Cu۳, Al۴Cu۹, AlCu۴, Al۲Cu, and AlCu phases. The results showed that the formation of intermetallic phases and severe plastic deformation in the welding area caused an increase in hardness. The highest hardness value in the stirred area was ۹۷.۸ Vickers at a rotation speed of ۹۰۰ rpm and an advance speed of ۳۶ mm/min.
