STUDY OF THE EFFECT OF MICROSTRUCTURE ON HYDROGEN EMBRITTLEMENT SUSCEPTIBILITY IN A Fe-Ni-Co BASED ALLOY BY POSITRON ANNIHILATION TECHNIQUE
用正电子湮没技术研究Fe—Ni—Co基合金组织对氢脆敏感性的影响

Positron annihilation,TEM,SEM and high purity high pressure hot charging of hydrogen have been used to investigate the effect of microstructure,changed by varying of Ti content, on the hydrogen performance of the Fe-Ni-Co based alloys.It was found that th
