| 摘 要： | 采用自制的千分表线膨胀仪,测定了AZ91D镁合金加热温度与膨胀量的关系,并通过同归分析求得AZ91D镁合金在特定加热速度下的膨胀量与温度的关系式,进而求得在特定的加热速度下AZ91D镁合金的线膨胀系数与温度的关系式,丰富了镁合金的物性参数数据,而且为镁合金的其他研究与应用提供了理论参考依据.

| Abstract: | The temperature-expansion curves of AZ91D magnesium alloys is measured with the home-made line-expand apparatus.The temperature-expansion formula of AZ91D magnesium alloys is acquired by linear regression analysis.And line-expand coefficient-temperature formula of AZ91D magnesium alloys is obtained,Physical parameters of magnesium alloys are enriched by the experimentation,it provides basic foundation for other research about magnesium alloys. |
