Abstract
For comparison with the results obtained from alloys of indium with solute metals from Group IIB of the periodic table, the lattice spacings of indium-magnesium and indium-lithium alloys have been measured. Although the results show an unexpected scatter, they establish that neither magnesium nor lithium cause a marked axial ratio decrease. A possible reason for this behaviour is briefly discussed. The solid solubility of magnesium in indium at room temperature lies between 35 and 40 atm% of magnesium. The primary solid solution enters into equilibrium with the previously observed face-centred cubic intermediate solid solution (denoted β) above 275°C, and with the ordered form of the same intermediate phase below this temperature. There is a peritectic reaction β+liquid = (indium-rich primary solid solution) at 333.5°C.
