 Abstract

- We manufactured the metal hydrides of (Ti_0.88Mg_0.12)H_2 using a very easy and cheap way that Ti-12%Mg blending powder was mechanically milled with liquid milling media such as isopropyl alcohol (C_3H_8O, containing oxygen) and hexane (C_6H_14, no oxygen) as hydrogen source. The (Ti_0.88Mg_0.12)H_2 synthesized in isopropyl alcohol contained the high oxygen of 11.2%, while one in hexane had the low oxygen content of 0.7%. Such a difference of oxygen content affected the dehydriding behavior, phase transformation, and microstructural evolution at high temperature, which was investigated through X-ray diffraction and DSC measurements, and electron microscope observations.
