Metastable microheterogeneity of melts in eutectic and monotectic systems and its influence on the properties of the solidified alloy

Experimental results that are the basis for the existence of metastable microheterogeneities in melts of eutectic and monotectic systems are summarized. Among these, recent results of small angle neutron scattering experiments are discussed in some detail. It is shown that the influence of a homogenizing heat treatment of a melt on the structure of crystalline castings and amorphous ribbons obtained after its solidification is very important.
