DOIAbstract
The effect of pressing temperature on microstructural development under ECAP conditionswas studied in an as-cast 7475 aluminum alloy at temperatures from 523 to 673 K. The samples were pressed by using route A up to strains of 12. Newequiaxial grains with high angle boundaries (HABS) start to be formed after three passes and then gradually developed with repeated ECAP, finally, followed by fully development of a new fine-grained structureyesBelgorod State Universit
