摘要
借助纳米力学测试系统测试经深冷处理后铝青铜的硬度和弹性模量。结果表明:深冷处理后铝青铜的硬度和弹性模量分别为3.82GPa和117.67GPa,且铝青铜的硬度随压入深度的增加而逐渐降低,反映出硬度存在的尺寸效应,但弹性模量不存在尺寸效应现象。
The hardness and elastic modulus of aluminum bronze after cryogenic treatment was measured by nanoindenter.The results show that the average hardness and elastic modulus of aluminum bronze after cryogenic treatment is 3.82 GPa and 117.67 GPa,respectively,and the hardness decreases with the increase of the indentation depth,the size effect phenomenon exists in the measurement of nanohardness,but does not exists in the measurement of elastic modulus.
