It was shown in this paper that, thermal stresses and
accompanying them plastic strains, generated during solidification and cooling
of casts of metal alloys, were the sources of acoustic emission. For casts,
which phase \alpha is deformed by slip, there is a possibility of determination
of initial temperature of casting mould by means of acoustic emission.
