Effect of High-energy Ball milling to Powders on Microstructure and Physical Properties of Al-50Si alloy Lijun Zhanga, Jingpei Xieb, Aiqin Wang Materials Science and Engineering School of Henan University of Science and Technology, Luoyang, 471003, China aexceley@163.com; bxiejp@mail.haust.edu.cn Keywords: high-energy ball milling; Al-50Si alloy; physical properties Abstract: Al-50Si can be fabricated with a method in which air-atomization is followed by vacuum canning hot-pressing process.
The second is that this kind of alloy is the lightest one using in the electronic packaging materials which has excellent comprehensive.
As we know, the tensile strength of materials are decided by the size of the grains.
