It is shown that the stress triaxiliaty T has great effect on the damage evolution. When T goes up, the ductile damage tends to be intensified. When the core is harder than the sleeve, the larger the semicone angle the core fracture is more likely to occur.

断裂预测结果表明，对于芯层金属较硬的双金属的挤压成形，锥形模半模角α越大，芯层金属越容易发生断裂，较大的摩擦因子有助于阻止芯层金属的断裂，这两点结论与Avitzur由上限法所得的结论完全一致。

The effect of heattreatment on bonding strength of the Cu./Al bimetal interface was also investigated. When the semicone angle or the percent reduction goes up, the relative slide will also increase. Suitable diffusion heattreatment can improve the bonding strength.
