Studies of Non-Metallic Inclusions in Basic Weld Metal (Report 5)

Vanadium Deoxidized

Abstract

Vanadium is a very weak deoxidizer being intermediate between chrominm and silicon. In this report vanadium was used as a single deoxizer in the straight lime electrodes. As a core rod extra low carbon steel was used. The weld metals have been attained by usual hand welding.
Inclusions located on the weld metals was extroated with carbon evaporated film, and investigated by means of the elecron microscope. The deoxidation products were proved to be vanadium oxide (V₂O₃). The form of oxide inclusions are usually angalar shaped particles, but vanadium carbides take the form of circular shaped film.
