Abstract
The solubility of hydrogen in liquid iron alloys has been studied by Sieverts' method at the temperature range from 1548° to 1672°C and under an atmospheric pressure of hydrogen. The solubility of hydro-gen in liquid iron decreases by the addition of B, Ge, Al, Sn, and Ta, and increases by the addition of Zr.
Interaction parameters at 1600°C are:∂log fAlH/∂[%Al]=0.0107……[%Al]<10.
∂log fBH/∂[%B]=0.058……[%B]<2.5
∂log fGeH/∂[%Ge]=0.0109……[%Ge]<10.
∂1og fTaH/∂[%Ta]=0.0017……[%Ta]<25.
∂log fSnH/∂[%Sn]=0.0057……[%sn]<7.
∂log fZrH/∂[%Zr]=-0.0088……[%Zr]<2.
