摘　　要：通过晶粒度、偏光等金相分析及力学性能、折弯测试,对5083合金板材折弯开裂试样进行了试验研究,结果表明,板材退火不充分,未达到完全再结晶是引起板材折弯开裂的主要原因。The bending cracked samples of 5083-O alloy sheet was tested and analyzed by the analysis of grain size,metallographic microstructure and tests of mechanical properties and bending crack.The cracking of 5083-O alloy sheet during bending was found to be attributed to insufficiency annealing and incomplete recrystallization.

关 键 词：退火 开裂 再结晶
