工艺参数对压铸AM60B合金微观组织的影响

Influence of Processing Parameters on Microstructure of Die Casting AM60B Alloy

采用液态压铸技术,研究了压铸工艺参数对AM60B合金显微组织的影响。试验结果表明,当浇注温度为680℃、模具温度为180℃、压射速度为3.0m/s、压射比压为75MPa时,压铸镁合金AM60B可以获得组织均匀细小、表面光滑、缺陷极少的铸件。

The effect of die casting processing parameters on the microstructure of AM60B alloy is studied by liquid die casting technology. The result of experiment shows that the castings of AM60B alloy with more uniform small structures,relatively smooth surface and little defect castings are made by controlling pouring temperature（680℃）, mold temperature（180℃）,die casting speed（3. 0m/s）and pressure（75MPa）.
