Heat treatment of rheo squeeze casting aluminum alloy parts

The heat treatment system of 7075 aluminum alloy wheel shaped parts formed by rheo squeeze casting was analyzed and tested. Through DSC analysis of the parts, different solution temperature ranges were determined. Through a large number of samples, a variety of heat treatment schemes with different solution temperature, solution...

Problems in research of Austempered Ductile Iron

Heat treatment is usually used in strengthening and toughening treatment of ductile iron. The heating temperature of most heat treatment processes is higher than the upper limit of critical eutectoid temperature (AC upper limit) of nodular iron heating, which involves the austenization process of nodular iron matrix structure, which...
