摘要: The effect of Fe on hydrogenation behavior 2:17 type SmCo alloys was investigated. as-cast Sm(Co bal Fe x Cu 0.068 Zr 0.034 ) 7.33 with (x= 0.251) and (x=0.265) are decrepitated under hydrogen pressure 0.3 MPa at room temperature, whereas the alloy (x=0.237) is not decrepitated. ability for obviously improved increase content. With content, network structures that consist easily hydrogen-decrepitation (HD) phase, including 1:5 phase 2:7 become fine well-distributed. heat-treated eliminated after heat treatment 1190 °C. All can be temperature. increasing HD result from improvement abilities 1:7 due to expanded unit cells part atoms entering into matrix phase.
