용융손실이 MmNi5 합금의 특성에 미치는 영향
The Effects of Fusion Loss on the Characteristic of MmNi5 alloy
Mischmetal(Mm) is substituted for La of AB5 type alloys because of the lower cost of Mm than La. But the equilibrium H2 absorption pressure is more sensitive to Mm than La. As the volatility of Mm is higher than other metal component of the AB5 alloy, it is significant to optimize the eXcess Mm quantity of a stoichiometry were investigated with XRD and PCT measurements.
