초록

The $Zr_{57}V_{36}M_7$ getter alloy was prepared by Fe substituting Ga or Y for Fe on $Zr_{57}V_{36}M_7$ getter alloy(St707), and the activation temperatures and the hydrogen a sorption speeds of these alloys were investigated. The activation temperatures of these alloys were estimated from the ultimate pressure-temperature curve and lowered about $100\~200\;K$ compared to $Zr_{57}V_{36}M_7$, fetter alloy(St707). However, final pressures at fully activated temperature were increased with substitution of Fe by Ga and Y on $Zr_{57}V_{36}M_7$ getter alloy. The hydrogen sorption speeds of these alloys measured by an orifice method were decreased about $0.460\~0.586liter/sec$ g compared to $Zr_{57}V_{36}M_7$ getter alloy.
