THERMAL EVOLUTION OF GASES BOMBARDED INTO COPPER-NICKEL ALLOYS,

Abstract

Copper, nickel, a 20/80 and a 50/50 copper-nickel alloy were argon ion bombarded in a 400V glow discharge. The rate of thermal evolution of the argon was determined during a linear temperature rise. At least 3 peaks in the thermal evolution curves of all samples were found below 800K. This thermal evolution was influenced by the alloy composition and by carbon monoxide adsorption after bombardment. After hydrogen bombardment evolution occurred only at low temperatures. After nitrogen bombardment evolution occurred only at high temperatures. Greatly enhanced uptake of hydrogen occurred after previous nitrogen bombardment. (Author)
