Development of Ti_(0.85)Zr_(0.17)(Cr-Mn-V)_(1.3)Fe_(0.7)-based Laves phase alloys for thermal hydrogen compression at mild operating temperatures

Metal hydride with proper hydrogen storage properties is the key component of hydride thermal hydrogen compressor.In this work,Ti_(0.85)Zr_(0.17)(Cr-Mn-V)_(1.3)Fe_(0.7)-based alloys were developed to achieve thermal hydrogen compression at mild operating temperatures of water bath.The results indicate the single C 14-type Laves phase as well as homogeneously distributed elements of all alloys.With increased Mn content in Ti_(0.85)Zr_(0.17)Cr_(1.2-x)Mn_xFe_(0.7)V_(0.1)(x=0,0.1,0.2,0.3)alloys.
