Effect of Cryogenic Treatment on Microstructure and Mechanical Properties of Aluminum Scrap Cans Alloy
Some cryogenic treatment experiments were carried out on aluminum scrap cans alloy at liquid nitrogen temperature for 48 h,and the mechaninal properties were tested and the microstructures were observed and analyzed.The experimental results show that cryogenic treatment can significantly improve the mechaninal properties of the alloy,the tensile strength and elongation is increased by 10.7% and 36.2%,respectively.
