Fatigue failure results from accumulation of cracks of deformation pro - cess of material.
疲劳破坏是材料在变形过程中产生的裂纹积累。

The new material is not only oil resistant, but also has fairly great improvement in performance of high temperature resistance, fatigue resistance and permanent deformation resistance.
新材料不仅具有耐油性,在耐高温性、耐疲劳性和抗永久变形性方面也有较大幅度的提高。

The results show that the increase of cyclic frequency would decrease high temperature fatigue lifetime of the alloy and result in different deformation mechanism.
