POWDER MATERIAL AND METHOD FOR MANUFACTURING MOLDED ARTICLE
To provide a powder material for additive manufacturing, which allows molding of a molded article in a three-dimensional shape with little cracks or chips and high hardness, and a method for manufacturing a molded article using the powder material.SOLUTION: The powder material for additive manufacturing is to be used for manufacturing a molded article in a three-dimensional shape by irradiation with laser light or an electron beam, and the powder material is composed of a first component comprising cobalt and at least one compound selected from vanadium carbide, niobate carbide and molybdenum carbide, an optional additive component, and the balance tungsten carbide. The content of the first component is 0.6 mass% or more and 5 mass% or less.SELECTED DRAWING: Figure 2
【課題】割れや欠けが少なく、かつ硬度が高い３次元形状の造形物を造形することが可能な積層造形用の粉末材料と、この粉末材料を用いる造形物の製造方法と、を提供する。【解決手段】レーザ光又は電子ビームを照射して３次元形状の造形物を製造するために用いられる、積層造形用の粉末材料であって、コバルトと、バナジウム炭化物、ニオブ炭化物及びモリブデン炭化物からなる群から選択される１つ以上で構成される第１成分と、任意添加成分と、残部タングステン炭化物と、からなる。前記第１成分の含有量は、０．６質量％以上５質量％以下である。【選択図】図２
