Chromium Base Alloys DEOXIDATION AND DENITRIFICATION STUDIES OF CHROMIUM AND THE EFFECT ON LOW TEMPERATURE PROPERTIES

摘要

The brittle to ductile transition temperature of commercial electrolytic chromium was investigated. Elements with a high affinity for oxygen, nitrogen and carbon were added to the chromium. The reaction products which formed and their effect on several properties of chromium were correlated with ductility criteria.nThe investigation showed that the transition temperature of chromium, as determined by three point bend tests, can be lowered by defoliation and gentrification techniques as well as by grain size refinement and by testing at reduced strain rates.
