摘　　要：研究了退火升温速率对汽车蒸发器管片料材料性能的影响。拉伸力学试验结果表明快速升温退火可明显改善力学性能的均匀性,同时改进管片料的冲压成型性能。金相分析试验结果表明快速升温退火后,材料晶粒尺寸均匀细化,有利于在后续冲压过程中避免冲压开裂问题,从而提高了产品成品率。Effect of fast annealing on the material formability property of automotive evaporator tube plate was investigated. Tensile testing results indicated that fast annealing could improve mechanical property evenness and material formability of the materials. Optical microscopy characterization of the alloy microstruetures revealed that fast annealing help to refine the grain size, which will avoid crack problem during forming process and hence increase the product yield of customers.
