研究了新钢种C15的化学成分、显微组织及力学性能之间的关系,并指出通过适当的热处理工艺可消除钢中的σ相等弥散质点.改变δ铁素体的形状及分布,从而获得最佳的力学性能。
The relationship between the chemical composition, microstructure and mechanical properties of the new steel C15 was studied and it was pointed out that the σ equivalent dispersoid could be eliminated by suitable heat treatment process, and the shape and distribution of δ ferrite were changed to obtain The best mechanical properties.
