    Influence of Deformation Temperature on the Texture of 1235 Aluminum Alloy after Compression by EBSD Technology

    • 摘要: 采用电子背散射衍射技术对经不同温度热压缩后1235铝合金的织构进行了研究, 分析了在50%变形量、0.1 s-1应变速率下, 变形温度对该合金晶粒取向、晶界特征及织构组分的影响。结果表明: 随着变形温度的升高, 织构的取向聚集性弱化, 织构相对体积总含量降低, 晶粒内小角度晶界更稀疏, 大角度晶界更加平直且连通性好, 再结晶晶粒长大更充分。

       

      Abstract: Texture of 1235 aluminum alloy after compression at different deformation temperatures was studied by electron backscatter diffraction (EBSD) technology. In addition, the effect of deformation temperature on grain orientation, grain boundary characteristic and texture component in the alloy was also analyzed at deflection of 50% and strain rate of 0.1 s-1. The results show that the aggregation of texture orientation was poorer with rising the temperature, the relative volume content of texture component decreased. Furthermore, the low-angle grain boundaries were distributed dispersedly while the high-angle grain boundaries were straighter with better connectivity. The recrystallization grains of 1235 aluminum alloy would grow more fully.
