The results show that the alloy undergoes obvious plastic elongation, the specimen fractures into four sections and the diameter changes from 16 mm to 12 mm. The fracture surfaces distribute randomly well developed and partially developed veinal patterns. The deformation behavior of alloy is non-Newtonian flow behavior. About 3% amorphous matrix of extruded specimen transforms crystal, the crystal particles with size of 10-20 mm are precipitated in the amorphous matrix, the thermostability of the extruded specimen was lowered. The failure of the alloy is mainly attributed to non-uniform viscous flow under high strain rate resulting from the hydrostatic extrusion process.

结果表明：非晶合金在高应变速率下产生了明显的塑性变形，直径从16 mm变为12 mm，断裂为4段，且样品断口上随机分布着充分发展与未充分发展的脉纹式切变带，由此可看出非晶合金的变形为非牛顿体变形行为；挤压后的样品约有3％的非晶相发生晶化，在非晶基体上析出10～20 nm的纳米晶粒，导致挤压后非晶合金的热稳定性降低；静液挤压高应变速率变形条件使非晶合金产生非均匀流变，是造成非晶合金断裂的主要原因。

The effects of strain rate on plastic formation and dynamic recrystallization of 7050 aluminum alloy were discussed. The results show that the deformation of the specimen is inhomogeneous, and the effective strain in the center of the specimen is maximum. The deformation inhomogeneity increases with the increase of strain rate. The effective stress of specimen is inhomogeneous. As the strain rate increases, the minimum stress value moves from the drum-shaped region to the heart of specimen. The standard deviation of dynamic recrystallization grain size decreases with the increase of strain rate.

模拟结果表明，热变形过程中，试样的各个部位的变形分布不均匀，心部的等效应变最大，变形的不均匀性随应变速率的增大而增大，但是变化的程度不大；试样内部各部位的应力大小分布不均匀，随应变速率的增大，最小应力值由自由变形的鼓形区域逐步向心部移动；动态再结晶晶粒尺寸标准偏差随应变速率的增加而减小。
