3J21合金箔片纳米压痕尺寸效应分析
Analysis of Size Effect in Nano-indentation Process of 3J21 Alloy Foil
摘要
Abstract
In the microscopic environment,analysis and research on the size effect of indentation can provide a powerful theoretical basis and technical guidance for exploring the characteristics of thin film and micro mechanical materials.Using two kinds of test methods,the nano-indentation tests are performed on the 3J21 alloy foil of 100 μm thickness,from which the mechanic parameters of the 3J21 alloy foil are obtained.The experimental data indicates that there is significant indentation size effect in the micro-nano scale.Three kinds of models are used to describe and analyze the indentation size effect of the 3J21 alloy foil.The results show that these three models can effectively describe the indentation size effect and the latter two models can accurately predict the true hardness value of the 3J21 alloy foil.关键词
