摘要：

Glassy, nanostructured and crystalline hydride-forming Mg1 - xNix alloys with five different compositions (0 less than or equal to x less than or equal to 0.33) were prepared by rapid quenching of the melt with the melt-spinning method. Glassy Mg-Ni alloys (Mg0.87Ni0.13 and Mg0.84Ni0.16) crystallize at around 438 K. During crystallization. an intermediate metastable Mg-Ni phase is formed. Hydrogen activation of these alloys requires temperatures and pressures above 663 K and about 1.5 MPa, respectively. Thereafter a very high storage capacity of nearly 6 mass% H was achieved with Mg0.87Ni0.13. (C) 1999 Elsevier Science S.A. All rights reserved.
