摘要 |
A casting of a white cast iron alloy and a method of producing the casting are disclosed. A white cast alloy is also disclosed. The casting has a solution treated microstructure that comprises a ferrous matrix of retained austenite and chromium carbides dispersed in the matrix, with the carbides comprising 15 to 60% volume fraction of the alloy. The matrix composition comprises: manganese: 8 to 20 wt %; carbon: 0.8 to 1.5 wt %; chromium: 5 to 15 wt %; and iron: balance (including incidental impurities). |
