含有粗大的铁素体晶粒和残留的热轧织构，引起力学性能的各向异性，导致了抗拉强度和延伸率的降低。
Big ferrites and hot rolling texture are left behind in particle structures, Which leads the anisotropy of mechanics, so the tensile strength and elongation rate reduce.
从热轧产品看：与本钢1700热连轧机相比，晶粒尺寸略小，强度值略高，延伸率略低。
Compared with Bengang 1700 hot rolling mill, the strip rolling product has smaller crystal granularity, higher strength value, and lower extension rate.
研究结果表明，药型罩材料的晶粒度对射流动态延伸特性有重要影响。
It was shown from experimental results that the performance of copper liner shaped charge jets are strongly dependent on the grain size of a initial liner.
合金在高应变速率的变形中通过动态再结晶可获得更细的晶粒尺寸，其断裂时总延伸率在135%左右。
They also show that a finer grain size can be obtained by dynamic recrystallization during superplastic deformation at a high strain rate, but the total elongation to failure is limited in about 135%.
研究结果表明：经过大变形后，由于纯铜的晶粒得以细化，抗拉强度、屈服强度、硬度和断裂延伸率都显著增加。
The results show the tensile strength, yield strength, hardness and elongation increased obviously due to the decreasing of the grain size of pure Cu after severe plastic deformation.
