<P>PROBLEM TO BE SOLVED: To provide a method for evaluating dynamic characteristics of steel capable of accurately evaluating the dynamic characteristics of steel with high hardness. <P>SOLUTION: A method for evaluating dynamic characteristics is the method for evaluating the dynamic characteristics of steel by an indentation method (method for evaluating dynamic characteristics of a desired area of the steel by pressing indenters into the area) using a plurality of triangular pyramid indenters having mutually different edge interval angles ϕ, for example, two triangular pyramid indenters constituted of diamond, and in which all the edge interval angles ϕ of the plurality of triangular pyramid indenters 1 are 115° or more. <P>COPYRIGHT: (C)2013,JPO&INPIT |
