Brittle-ductile transition in vanadium

Mechanical tests were made on two grades of vanadium over a range of temperatures below 25 deg C to establish the existence of a brittle-ductile transition and the temperature range over which it occurs. Also, the effect of small amounts of metallic and nonmetallic additions on the brittle-ductile transition in vanadium was determined. Some of the physical properties of vanadium were determined through the transition temperature. The results and conclusions of this investigation are summarized. (auth)
