for metastable b-type TB8 alloy. The microstructures of hydrogenated TB8 alloy were investigated based on scanning electron microscopy(SEM), transmission electronic microscopy(TEM) as well as X-ray diffraction(XRD) analysis. The results reveal that d hydride phase forms in the hydrogenated TB8 alloy, but the amount of b phase increases with hydrogen content increasing. Single b phase appears when......
