よって球状化するが、冷却速度が大きいときには、溶融
粉体が球状化する以前に凝固してしまうので、不規則形
状の粉末となる。In this powder manufacturing method, if the cooling rate after the molten alloy is powdered is slow, it will become spheroidized due to the surface tension of the molten powder, but if the cooling rate is high, the molten alloy will solidify before it becomes spheroidal. This results in irregularly shaped powder.
