Research Status of Characterization on Damage of Metal Materials Based on the Electrical Resistance Method

  • 摘要: 电阻率对金属材料微观组织变化具有精确性和敏感性。近年来,随着微电阻测量精度的不断提高,基于电阻法的金属材料损伤表征研究开始大量出现。综述了不同金属材料试样在拉伸韧性损伤、高温时效损伤、高周疲劳损伤和蠕变损伤过程中弹性模量、拉伸强度、断裂韧性、硬度、时效时间和疲劳周次等参量与电阻参量的映射关系,探讨了损伤导致电阻变化的微观机理,指出了今后微电阻法的主要研究方向。
    Abstract: Resistivity is precise and sensitive with the change of microstructure. In recent years, the characterization on damage of metal materials based on the method of electrical resistance has been studied widely with the increment of precision of electrical resistance measurement. The mapping relationship of the parameter of elasticity modulus, tensile strength, fracture toughness, hardness, aging time, fatigue time etc. and the parameter of electrical resistance were reviewed in this paper, the values of these parameters of different metal materials were measured at different damage environments such as drawing, high temperature aging, high cycle fatigue and creeping. The micromechanism of electrical resistance changes, which was influenced by deformation, was discussed. In addition, the main research orientation in this field was predicted.
