摘要
对采用液态压铸技术,研究了压铸工艺参数对AM60B镁合金组织缺陷的影响.试验结果表明,当浇注温度为680℃、模具温度为180℃、压射速度为3.0 m/s及压射比压为75 MPa时,可以获得组织均匀细小、表面光滑、缺陷极少的AM60B镁合金铸件.
The effect of die casting processing variables on microstructure defects of AM60B magnesium alloy has been studied by liquid die casting technology. The result of experiment shows that the castings of AM60B magnesium alloy with uniform fine microstructure, relatively smooth surface and little defect can be made by controlling pouring temperature at 680℃, mold temperature at 180℃, injecting speed of 3.0 m/s and injecting pressure at 75 MPa.
