摘要
采用激光快速熔凝技术对4种成分Ni-Sn合金进行处理,研究了Ni-Sn合金在熔凝过程中的组织演变。结果表明,与温度梯度相比,激光扫描速度对Ni-Sn合金形貌的影响作用更大。通过建立模型计算出的Ni-Sn合金一次枝晶间距为15.38μm,与实验结果相一致。
The microstructure of Ni-Sn alloy with rapid laser remelting was studied. The results show that the effect of laser scanning speed is more significantly than the temperature gradient on the microstructure of Ni-Sn alloy. The primary dendrites space of Ni-Sn alloy is 15.38 μm by establishing a model, which is consistent with the experimental results.
