Abstract

The growth of requirements for the properties of steel, as a rule, outstrips the development of technological techniques aimed at improving the purity of the metal. In the castings manufacture, regardless of the technology, the production of a mold is one of the most common defects that significantly reduce the quality of castings, which are defects of shrinkage origin. The global causes of their formation may be errors in the design of technology, as well as disruption of production processes. During the research, several types of defects occurred. The article considers only defects with shrinkage origin. Most machines, machines and parts are subjected to cyclic loads during operation. Therefore, the problem of endurance of materials is relevant for railway, automotive, aviation, shipbuilding, machine tool, energy and other industries.
