Sintered Ti-system material product derived from injection molding of powder material and producing method thereof |
摘要 |
Disclosed is a sintered Ti-based material product derived from injection molding of a powder material. The outer layer region of the product comprises a lower amount of carbon than the inner layer region of the same. The inner layer region comprises a Ti-based carbide which has an average grain size of not less than 1 mum and which is dispersed in the inner structure to have an area fraction of not less than 0.1% to not more than 20%. The outer layer region comprises a lower amount of Ti-based carbide than the inner layer region. There can be observed an area fraction of less than 0.1% of the Ti-based carbide at the surface of the sintered Ti-based material product.
