POWDER-METALLURGY STEEL ARTICLE WITH HIGH VANADIUM-CARBIDE CONTENT |
摘要 |
<p>A powder metallurgy tool steel article for use in applications requiring high wear resistance having a carbide content of 10 to 18 volume percent of substantially all MC-type vanadium carbides, which carbides are substantially spherical and uniformly dispersed; the carbon content of the article is balanced relative to the carbide formers vanadium, chromium and molybdenum to provide an amount of carbon in the matrix of the article sufficient to permit the article to be heat treated to a hardness of at least 56 Rc. *****</p> |
