Методика определения предела текучести углеродистых сталей

A technique for determining the yield point of materials is described. The procedure is based on determination of the diameter of the build-up zone around the cone indenter impression (lip angle is 90°) at a constant load. The diameter of the build-up zone is determined by recording the depth and height of indentation on the original surface. The method is intended for engineering strength calculations and evaluation of the strength properties of materials.
