0　前言高铬白口铸铁现在很少在铸态下使用,尽管在某种情况下,作为铸态组织或许是优越的,但是大多数还是通过控制化学成分和热处理来获得所要求的性能。此外,通过改变热处理,同样的合金能够获得不同的性能,甚至可以更准确地说,为了获得更好的性能,热处理比化学成分更重要。虽然 0 Introduction High-chromium white cast iron is rarely used in the cast as it is nowadays. Although it may be advantageous as a as-cast structure in some cases, most of the properties are achieved by controlling chemical composition and heat treatment. In addition, by changing the heat treatment, the same alloy can achieve different properties, and even more accurately, heat treatment is more important than chemical composition for better performance. although
