DETERMINATION OF TENSILE STRENGTH USING CONTINUOUS INDENTATION TEST

摘要

The invention that by using a continuous indentation relates to a method for deriving a tensile strength for a given metal, the invention To this end, includes a method for deriving the art metal work hardening index, stress factor of through continuous indentation.; The invention is typically tensile strain correction coefficient value to be applied for different types of metal, when the tensile strength of the obtained selected metal And Tensile strength equation is defined, including Characterized in that the use.; In addition, the present invention in consideration of the file up / Sync In (pile-up / sink-in) caused around the press during derived work hardening index, stress factor of a specific metal for the contact radius and the strain of the indenter and the sample It characterized in that it is by lowering the new definition, results through indentation so as to be closer to the result through a tensile test.; In addition, the present invention by replacing a tensile test using an indentation test, the time required during the tensile test, the effect of reducing the cost.
