A method for the heat treatment of an iron-based cast object and the article produced by this process.

摘要

A casting material for thixocasting, comprising an Fe-C-Si-base alloy which exhibits a chevron-shaped endothermic portion in the latent heat distribution curve and has a eutectic crystal content Ec of above 10 % by weight to below 50 % by weight. The alloy comprises 1.8 to 2.5 % by weight of carbon and 1.4 to 3 % by weight of silicon with the balance consisting of iron and unavoidable impurities.
