摘要 |
The invention relates to a method for producing high-performance Cr-Ti-V hydrogen storage alloys utilizing a thermit process, whereby residence of adversely affecting impurities is inhibited, addition of not less than 10 at % of Ti as an alloy component is realized, and thermal burden on the crucible used in the method is reduced. The method includes the steps of: (A) providing an alloy material ( 1 ) comprising a Cr oxide, a V oxide, and a reducing agent Al, and an alloy material ( 2 ) comprising Ti; (B) placing the alloy materials in a crucible for thermit reduction so that the alloy material ( 1 ) is placed above the alloy material ( 2 ); (C) igniting the alloy material ( 1 ) placed in step (B) and melting all metal elements contained in the alloy materials the with heat of the thermit reaction of the alloy material ( 1 ); and (D) making the alloy melt obtained in step (C) into an alloy.
