Examination of formability of cast aluminium alloy
Ring upsetting has been used to upset AlSi9Cu3 cast alloy in order to examine formability as well as the effect of deformation. Maier scalar quantity, which characterises the stress state, has been calculated. It is concluded that, from the point of view of maximum deformation, ring upsetting tests are more advantageous than simple upsetting tests.
