大家好

  请问  有谁知道,再测某物质的力学曲线时          咋样根据物质的硬度 来选择所需的探针     来测出比较好的力曲线  可以得到很好的拟合

如果需要定量力学数据,则选择探针有一定的要求,即必须可使样品发生一定程度的形变。对于杨氏模量范围1 MPa < E < 20 MPa的样品,应选择scanasyst-air的探针; 5 MPa < E < 500 MPa的样品应选择Tap150的探针;200 MPa < E < 2000 MPa的样品应选择Tap300A的探针;1 GPa < E < 20 GPa的样品应选择Tap525A的探针;10 GPa < E < 100 GPa的样品应选择DINSP-HS的探针。
