摘要(Abstract)：

通过固溶前退火温度来调控2519A铝合金棒材固溶时的再结晶状态,以获得不同织构组态。采用X射线衍射分析研究了2519A铝合金棒材经150、200、300和350℃退火1 h后再经535℃×2 h固溶与直接经535℃×2 h固溶4种热处理工艺对合金织构和微观组织的影响。结果表明:2519A铝合金棒材直接经535℃×2 h固溶,挤压棒材强的〈13〉织构转变为〈110〉再结晶织构,而经上述4种温度退火和535℃×2 h固溶,织构分别演变为〈113〉,〈605〉,〈5110〉和〈7 214〉织构。退火后不固溶试样〈111〉织构和硬度值都保持不变。样品固溶发生再结晶的〈110〉织构与挤压〈13〉织构间可用40°〈111〉长大理论解释。
