摘要
采用夏普冲击试验研究了一种新型软/硬层状紫铜/黄铜复合金属材料的冲击性能。结果表明,软/硬层状紫铜/黄铜复合材料的冲击韧性优于单相紫铜和单相黄铜。断口分析表明,优异的冲击韧性是由冲击过程中出现许多变形裂纹或界面分层,这消耗了大量能量,从而减少了裂纹的传播驱动力。本文通过一种新的结构设计策略拓宽了对金属材料力学性能的提升方法。
The impact properties for a novel sof/hard multilayered copper/brass composites was explored based on Charpy impact testing.The results show that the impact toughness of sof/hard laminated copper/brass composites is better than that of pure copper/brass.The superior impact toughness is explained by that lots of crack deflection or interfacial delamination appears during the impacting process that consumed huge energy and thereby reducing the driving force of crack propagation.This work broadens the enhancement methods on the mechanical performance of metallic materials by a new structural design strategy.
