摘要
采用自制的楔形试样研究了不同的铝含量(Al≥30%)及冷却速度对合金微观组织及硬度的影响。结果表明,合金的二次枝晶臂间距随冷却速度的增加明显减小;而合金的硬度主要与其中铝含量有关,且随铝含量的增加而增大。
The effect of cooling rate and Al content （A1≥30%） on the microstructure and hardness of Zn-based alloy was investigated by a wedge-formed sampl, The results show that the secondary dendrite arm space decreases decreases with the increase of the cooling rate. The hardness of the alloy is mainly correlatire with Al content and it further increases with the increase of Al content.
