Abstraksi:THE EFFECT OF TOLUENE SOLUTION ON THE HYDROGEN ABSORPTION OF rnr Mg-Ti ALLOY PREPARED BY SYNTHETIC ALLOYING. The synthesis and characterization of the Mg-Ti alloy have been carried out through a mechanical alloying technique under toluene solution. The Mg and Ti powders are milled for 10, 20, and 30 h in a high energy ball mill. The milled alloys are then hydrided at a temperature of 300°C in order to investigate the possibility used for hydrogen storage materials. The refinement analyses of the x-ray diffraction patterns show that mechanical alloying of the Mg- Ti powders under toluene solution results in the formation of the Til-l, and Mg-'I'i phases. Quantitative analyses indicate that the mass fractions of the Til-l, and Mg-T: phases are 62.90 % and 30.60 %, while the value for Mg and Ti amount to 2.6 wt% and 1.25 wt%. On hydriding at a temperature of 300°C, the milled powders are transformed into MgzTiH4, Til I, and v-MglI, phases with the mass fractions of 25.48 wt%, 64.0 wt%, and 10.52 wt%, respectively. Microstructure analyses show that before milling the shape of particle is mostly a ball shape, after 30 h of milling the shape of particles changes into polygonal shape, and upon hydriding the shape of particles changes from a polygonal shape into an irregular one. The final composition of the specimen after hydriding exhibits that Mg- Ti alloy can be promoted as a hydrogen storage material.
