Russian Engineering Research Aims and scope

Abstract

For the example of 09G2S steel Charpy samples, the impact strength and failure mechanism of low-alloy steel is considered in impact flexure at 213–293 K. The initial samples are compared with samples subjected to equal-channel angular pressing.
