Research on Microstructure and Mechanical Property of the Production of Al-Si Alloy by Electric Warming
Adopting quartz plate filter of 20 mesh to filter the ZL102 alloy compounded by Al-30Si coarse alloy produced by electric warming, the Fe content in the alloy is reduced to 0.43% from 1.14%, the big massive and petaloid Fe phase becomes fine block-like. The tensile strength and elongation of the alloy arrive at 182MPa and 4.3% respectively, which increased by 38% and 290% separately compared with the alloy without filtration. The mechanical property of this alloy has been close to the alloy compounded by pure Al and it can fully meet the demand of commercial production.
