PRODUCTION AND PROPERTIES OF THE HIGH PURITY CHROMIUM

Abstract

High purity chromium and chromium base alloys have excellent oxidation resistance and strength at high temperature. But they have never been used as heat resistant materials, as they are extremely brittle at room temperature. A recent research dy Wain and Greenaway, however, gives a great promise to this problem. They have succeeded in the preparation of chromium and its alloy which show a room-temperature ductility by very careful purification and mechanical working. This paper summarizes many researches, including Wain's, on the production and properties of high-purity chromium.
