Abstract
We manufactured the metal hydrides of <TEX>$(Ti_{0.88}Mg_{0.12})H_2$</TEX> using a very easy and cheap way that Ti-12%Mg blending powder was mechanically milled with liquid milling media such as isopropyl alcohol (<TEX>$C_3H_8O$</TEX>, containing oxygen) and hexane (<TEX>$C_6H_{14}$</TEX>, no oxygen) as hydrogen source. The <TEX>$(Ti_{0.88}Mg_{0.12})H_2$</TEX> 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.
