Abstract | 本发明提供一种非晶合金增材的制备方法,所述制备方法包括:使用高于被加工金属材料的等离子频率的脉冲激光对所述金属材料进行加热至融化,并通过限定脉冲激光的脉冲宽度为10fs‑1ms实现所述金属材料融化后的快速冷却。所述制备方法可以制造非晶合金三维零件,可避免非晶合金中纳米晶粒的产生,且可适用的非晶合金成分显著大于现有技术所覆盖的非晶合金成分区域。 |
Other Abstract | The invention provides a preparation method of an amorphous alloy additive. The preparation method comprises the following steps of heating a metal material by using pulse laser of which the frequencyis higher than the plasma frequency of the processed metal material until the metal material is molten, and quickly cooling the molten metal material by limiting the pulse width of the pulse laser tobe 10fs-1ms. According to the preparation method, a amorphous alloy three-dimensional part can be manufactured, generation of nano-crystalline grains in the amorphous alloy can be avoided, and applicable amorphous alloy components are remarkably larger than those of an amorphous alloy component area covered in the prior art. |
