摘 要: 测试不同热处理制度下Ti-1300钛合金的室温拉伸性能，利用逐步回归法对Ti-1300钛合金热处理制度与室温拉伸性能进行回归分析，建立了热处理制度与拉伸性能之间的回归方程。误差分析表明， 所建立的回归方程具有较高的精度，所有数据点均落在10%的误差带内。该回归方程可用于指导Ti-1300钛合金热处理工艺的制定。

Abstract:The tensile properties at room temperature under different heat treatment systems were tested. Furthermore, the regression analysis was carried out to the heat treatment and tensile properties of Ti-1300 alloy based on stepwise regression method and regression equations through the analysis of variance. The error analysis shows that the constructed constitutive relationship has good accuracy and can preferably describe heat treatment system of Ti-1300 titanium alloy.
Key words: titanium alloy; tensile properties; stepwise regression method; regression analysis
