热处理工艺对Fe_3Al室温力学性能的影响

Influences of Heat Treatment Technology on the Mechanical Properties of Fe_3Al at Room Temperature

本文比较了添加Ｃｒ合金元素的Ｆｅ_３Ａｌ金属间化合物在不同热处理工艺条件下的室温力学性能。通过轧制后的二次７００℃／ｌｈ油冷处理，合金的室温塑性有较大的改善。

The comparison of the mechanical properties at room temperature of Fe3Al inter-metallic compound added with alloy element Cr which is heat treated at different conditions is brought out in this paper. Through twice oil cold treatments by 700℃/h, a significant improvement of plasticity of the alloy at room temperature is obtained.
