结果表明，随着S含量的增加，导致固液两相区、温度范围和偏析程度明显加大，引起合金的热塑性降低。

The results showed that the solid liquid phase zone, temperature interval and segregation degree may be obviously enlarged with increasing s content so as to reduce the hot plasticity of the alloy.

在所研究的剪切应力、剪切速率及温度范围内，两者均属于假塑性流体，呈现剪切变稀行为。

The results show that HDPE/MMT nano-composite and HDPE belong to pseudoplastic fluid and present, shear thinning behaviors within the range of shear stress, shear rate and temperature.

锡可有效改善钢材的易切削性能，原因是在切削温度范围内富集在晶界的锡使钢材的塑性降低。

It improves the machinability of steels because of brittlement of grain boundaries resulting from the tin segregating on the grain boundaries of the steels.
