Experimental Study on the Resistance to Hydrogen Embrittlement of NIFS-V4Cr4Ti Alloy

摘要

There are more and more countries to ake an effort to the studies of vanadium alloy for fusion application. NIFS in Japan has recently developed an 80 kg heat V4Cr4Ti alloy (NIFS-heat 2) after the production of a 500 kg scale V4Cr4Ti in U. S. several years ago. Property evaluation of the alloy has beenput into an international collaboration program under the coordination of IEA (International Energy Agency). SWIP has joined the collabration on the hydrogen embrittlement resistance evaluation of the alloyt.
