Development of a methodology and means of non-destructive testing of physical and mechanical characteristics of cast irons to create grades with improved properties

Abstract

The article is devoted to the development of methods and means of non-destructive testing of physical and mechanical properties of cast irons in order to create new grades with improved characteristics. The choice of geometric parameters of indenters is considered, which provide high sensitivity to changes in characteristics in the volume of the material, and also allow achieving various levels of deformation and deformation rates during testing, which is necessary for analyzing the behavior of the material under dynamic loads. The results of the study will help to accurately determine the value of the plastic imprint necessary for an objective assessment of the physical and mechanical characteristics of cast iron.
