Combining the casting and punching technology

Abstract

In the article there are presented the results of studying the microstructure of metals obtained by the method of casting and punching in equal-channel step matrixes (ECSM). The analysis of the microstructure of metals obtained on the scanning and transmission microscope showed that owing to realization of intensive shift deformations on the inclined portion of ECSM there emerge shear bands which extend practically in parallel to zones of the matrix channels connection and influence positively closing and sealing all internal defects of cast blanks.
