| 摘 要： | 建立了7A04铝合金构件深冷处理过程瞬态温度场的有限元模型，对7A04铝合金材料在低温状态下的若干物性参数进行了实验研究，并运用温度场反算法分别得到了铝合金试件与低温（热）介质之间的传热系数。运用ABAQUS6．5有限元软件，对7A04铝合金构件瞬态温度场的数值结果表明，在淬火、深冷与上坡淬火过程中，构件上端部位存在很陡峭的温度梯度。

| Abstract: | The FEM model of 7A04 aluminum component was proposed to calculate transient temperature distributions during cryogenic treatment. Some property parameters of 7A04 aluminum alloy were obtained upon experimentation for the numerical simulation of cryogenic treatment. And an inverse temperature field method was used to compute the heat transfer coefficient between 7A04 aluminum specimen and hot or cold quenching medium. Using commercial FEM code ARAQUS 6.5, the results obtained show that very steep thermal gradient exists on the upper of the 7A04 aluminum component during quenching treatment, cryogenic treatment and uphill quenching treatment. |
