Melting shock waves in aluminum were studied using a moving window molecular dynamics (MW-MD) technique. It was found that shock compression in the  crystallographic direction leads to the formation of an overheated metastable solid state. This state is located on an extension of the solid branch of the T-P Hugoniot above the melting line. The melting of the overheated crystal is accompanied by a temperature decrease in the downstream flow behind the shock front. By contrast, shock compressions in the  and  directions result in a so-called "cold" melting that takes place below the melting line. This metastable supercooled state, lying on the extension of liquid branch of the T-P Hugoniot below the melting line, eventually undergoes a recrystallization associated with a temperature increase in the after-shock flow.
