结果表明:随着搅拌温度的降低至液相线附近时,电磁场对熔体凝固行为的影响逐渐显著;α初晶中树枝晶不断减少并逐渐转变蔷薇状晶和非枝晶;水淬后Al-Si共晶组织也由粗大的片层状转变为细小的纤维状和鳞片状结构。

The results show that as for the as-cast castings, eutectic Si particles are characterized as fibrous or long acicular shape as well as in homogenous distribution, and the impact absorbed energy varies from 1.17 to 2.35J. After T6 heat treatment, the eutectic Si particles become small granular or short bacilliform, and the aspect ratio and area fraction of Si particles decrease evidently. The energy of the T6-treated castings is 1.45-3.80 J, which is higher than that of the as-cast castings. Furthermore, the fracture mechanisms of different regions in the castings were analyzed and discussed.

结果表明:铸态下共晶Si粒子大多为纤维状或长针状,呈不均匀的网状分布,冲击吸收功在1.17~2.35J的范围内变化后;经T6热处理后,团簇状Al-Si共品相明显减少,共晶Si粒子呈现出粒状或短棒状,且细小均匀,Si粒子的长宽比和面积分数都有显著降低,冲击吸收功在1.45~3.80J的范围内变化,比铸态有明显提高。

The fibril diameter is in inverse proportion to deformation and the fibril length is in direct proportion to the square of deformation approximately. The ultimate tensile strength of the cladding wire by drawing at room temperature goes up in direct proportion to square root of deformation, whereas the elongation decreases and fluctuates.

结果表明:显微组织自原始的等轴晶变为细长条纤维状,纤维直径与形变量近似地成反比,纤维长度与形变量的平方近似地成正比;经室温拉变形的铜包铝线的极限抗拉强度随形变量增大而增大,与形变量平方根呈直线关系;延伸率随形变量增大逐渐降低,但延伸率波动较大。
