Abstract：
For the problem that the value of test force will influence the result of instrumented indentation hardness test, the relation between test force and instrumented indentation hardness, indentation modulus were investigated. 55 groups of tests were carried out, in which the test force were divided to 11 different levels. On the basis of 110 test data, differences were analyzed and the relation curves were plotted by Origin. And the relative difference value was proposed. Results show that when 19. 61N≤Fmax≤98. 07N, the change of test force makes little influence on instrumented indentation test (IIT) results and coefficient of variation(CV); when 0. 98N≤Fmax≤9. 81N or 196. 14N≤Fmax≤294. 21N, the change of test force makes remarkable influence on IIT results and CV. © (2014) Trans Tech Publications, Switzerland.
