本研究主要是探討AZ31鎂合金添加碳材及金屬添加劑，碳材添加劑選用奈米碳管(Carbon Nanotubes, CNT) ，金屬添加劑選用鎳(Nicekl, Ni)、釩(Vanadium, V)、鐵(Iron, Fe)，作為催化劑，探討碳材及金屬混合添加物對AZ31鎂合金儲氫性能的影響。此外本研究亦探討經不同製程，製備鎂基儲氫材料對儲氫性能的影響，首先將AZ31鎂合金添加催化劑以鑄造的方式，製備鎂基複合材料，再分別以等徑轉角擠壓(Equal channel angular pressing, ECAP)，高能量球磨(High Energy Ball Milling, HEBM)，以及經等徑轉角擠壓再以高能量球磨製程，三種不同製程的加工，以相近的製程時間為比較標準，最後進行吸放氫量測。
研究結果顯示，經等徑轉角擠壓再以高能量球磨製程後，最有效提升 AZ31 鎂合金之儲氫性能，儲氫性能由大至小為添加奈米碳管與鎳、奈米碳管與釩、奈米碳管與鐵，而AZ31鎂合金添加碳材金屬添加劑，在經ECAP製程後，反而造成儲氫性能下降，在經各製程之比較中，未添加碳材金屬添加劑之AZ31 鎂合金經 ECAP 製程有較好之儲氫性能；而添加碳材金屬添加劑之AZ31 鎂合金經HEBM製程、經ECAP與 HEBM混合製程，則明顯提升AZ31鎂合金之儲氫性能。

This study investigates the effect of carbon and metallic additives on the hydrogen storage properties of AZ31 magnesium alloys. Carbon additives carbon nanotubes (CNT), metallic additives nicekl (Ni), vanadium (V), iron (Fe), Discuss the effect of carbon and metallic additives on the hydrogen storage performance. also explored the effect of different processes on hydrogen storage properties, the AZ31 magnesium matrix composites with additives were prepared by casting ,and then processed by equal channel angular pressing (ECAP), high Energy Ball Milling (HEBM) and after ECAP then HEBM Three different processes, use the similar process time as a benchmark. Finally, the measurement of hydrogen absorption and desorption is performed.
The results show that after ECAP then HEBM processes the most effective improve the hydrogen storage performance of AZ31 magnesium alloys. The increase in hydrogen storage performance from large to small additions of carbon nanotubes with nicekl, carbon nanotubes with vanadium, carbon nanotubes with iron, AZ31 magnesium alloys after ECAP processes Instead, it decrease in hydrogen storage performance. Compared in various processes without added carbon and metallic additives has better hydrogen storage performance through the ECAP process performance through the ECAP process, while the AZ31 magnesium matrix composite with carbon and metallic additives added has better hydrogen storage performance through the HEBM process, through the after ECAP then HEBM process.
