摘要: 采用电子背散射衍射(EBSD) 技术研究了不同温度轧制的Pb--0.09Ca--1.5Sn--0.026Al (质量分数,%) 合金经后续270 ℃/10 min退火后的晶界特征分布 (GBCD).结果表明: 经室温和液氮 (-196℃) 轧制的样品中出现了 比较多的Σ3, Σ9和Σ27特殊晶界, Σ3晶界比例超过了60 %, (Σ9+Σ27)晶界比例超过了12 %, 并且特殊晶界有效地 阻断了一般大角度晶界的网络连通性, 表明合金的GBCD被优化;在100 ℃轧制的样品中特殊晶界比例较少, Σ3 晶界比例在30 %左右, (Σ9+Σ27)晶界比例在3 %左右, 特殊晶界不能有效地阻断一般大角度晶界的网络连通性, 合金的GBCD没有被优化.通过基于EBSD的单一截面迹线法对共格和非共格Σ3晶界进行了区分测定, 显示被 优化的晶界特征分布中, 非共格$\Sigma$3晶界是主要部分

Abstract:The grain boundary character distributions (GBCD) of Pb-0.09Ca-1.5Sn-0.026Al alloy (mass fraction, %) rolled at different temperatures and then annealed in the same way (270℃/10min) were investigated by means of electron back scatter diffraction (EBSD)techniques. The results showed that special boundaries such as ∑3, ∑9 and ∑27 were largely populated in the specimen which was rolled at room temperature and the temperature of liquid nitrogen(-196℃), the fraction of ∑3 and ∑9+∑27 boundaries exceeded 60% and 12%, respectively. The connectivity of general high angle boundaries (HABs) networks was interrupted substantially by special boundaries, indicating the optimization of GBCD was achieved. However, much lower fraction of special boundaries were developed in the specimen which were rolled at 100℃, and the connectivity of general high angle boundaries (HABs) network was not interrupted significantly, implying the GBCD was not optimized. Single section trace analysis based on EBSD technique revealed that incoherent 3 boundaries took the major parts of of 3 boundaries in the optimized GBCD
