摘要

摘要采用搅拌摩擦焊成功地焊接了5mm厚的Al-Mg-Mn-Sc-Zr合金板。实验采用三因素五层中心复合材料设计。采用响应面方法（RSM）建立数学回归模型。通过使用响应面图优化FSW工艺参数，以最大限度地提高硬度、拉伸强度、%伸长率、冲击强度和弯曲强度，并在确定的最佳条件下通过确认试验验证了结果。

Optimization of Process Parameters for FSW of Al-Mg-Mn-Sc-Zr Alloy Using CCD And RSM

Abstract Al-Mg-Mn-Sc-Zr alloy plates of 5mm thick were welded successfully using Friction stir welding (FSW). Three-factor five-level central composite design was adopted for experimentation. Response surface methodology (RSM) was employed to construct a mathematical regression model. Optimization of FSW process parameters obtained by using response surface plots for maximize hardness, tensile strength, %elongation, impact strength and bending strength, the results were validated with confirmation tests at identified optimum conditions.
