Compared to the cast ingots without ultrasonic melt treatment, hardness of homogenized as-cast alloy increases by 10% and its elongation increases from 3.8% to 7.7%, meanwhile its electric conductivity and tensile strength improves respectively. 熔体经超声处理铸态均匀化合金与未经超声处理的合金相比,布氏硬度提高10%,伸长率由3.8%提高到7.7%,电导率和抗拉强度也有所提高。
Then, the homogenized alloy was hot rolled, annealed and cold rolled into a sheet with thickness of 2.2 mm. 合金经均匀化、热轧、中间退火、冷轧成2.2mm厚的板材。
