摘要 利用原位X射线衍射方法研究了加热过程中6351Al合金喷丸变形层显微结构的变化,用线性分析方法计算出晶块尺寸和显微畸变。结果表明,喷丸使材料表层晶块细化,织构消失并且在加热后不再出现。随加热时间的延长和加热温度的提高,晶块长大,显微畸变减小。 The microstructure of 6351Al alloy during heat treatment was investigated utilizing in-situ X-ray diffraction method. Domain size and microstrain were calculated by modified warren-averbach method and voigt method. The results show that shot peening makes the domain on the surface of 6351 Al alloy finer, the textures of 6351Al alloy is randomized by shot peening and does not appear again after heat treatment. Domain and microstrain has grown and released respectively with the increase of heating time and temperature.
