Abstract

The results of the microstructure examination by light and scanning electron microscopy (SEM) and electron microprobe analysis of nonmetallic inclusions in high-strength invar alloys, deoxidized on various embodiments, are presented. The most suitable chemical composition of deoxidizing mixture is proposed.

Keywords
