Beschreibung
Zusammenfassung:	A powder material comprising an atomized powder of a Ni-based alloy containing inclusions, in which the number of inclusions contained in 10,000 particles of the atomized powder is 100 or less. The laminated molded article is composed of a Ni-based alloy containing inclusions, and the number of inclusions contained in a cross section is 100/mm2 or less. And a method for producing the powder material by a gas atomization method using an inert gas. 一种粉末材料，其由含有夹杂物的Ni基合金的雾化粉末构成，在10000个雾化粉末的粒子中，所含有的夹杂物的粒子数为100个以下。一种层叠成形品，由含有夹杂物的Ni基合金构成，剖面中所含有的夹杂物的数量为100个/mm2以下。通过使用惰性气体的气体雾化法制造上述粉末材料的粉末材料制造方法。
