| 摘 要： | 利用Cleeble－1500对玻璃铝基复合材料在温度为573—723K、应变速率为0．01s^-1～10s^-1的条件下进行高温压缩变形行为的研究。结果表明，应变速率和变形温度变化强烈影响复合材料的流变应力，流变应力随变形速率的提高而增大，随变形温度的升高而降低；玻璃铝基复合材料高温塑性变形时的流变行为可用Zener·Hollomon参数的双曲正弦函数来描述。

| Abstract: | High temperature compressive rheology of glass/aluminum matrix composites was performed using Gleeble-1500 thermal simulator in the range of deformation temperature from 573 to 723K, strain rate from 0.001 to 10 s^-1. The results show that the flow stress is controlled by strain rate and deformation temperature, the flow stress increases with the increase of strain rate and decreases with increase of temperature; The flow stress of the composites during high-temperature deformation can be described by hyperbolic sine function of parameter Zener-Hollomon. |
