摘要：

A special interest for studies has a deformation dissolution of stable and metastable aluminides of twice phase Al alloys with transition metals (Zr, Fe, Cr) by severe plastic deformation (high pressure torsion). It was determined a kinetic of deformation dissolution of the Al7Cr and Al13Fe4 stable alurninides and the Al3Zr and Al6Fe metastable intermetallic-compound crystals. It was established that metastable crystals of Al3Zr fully dissolved in Al matrix and super saturated Al-base solid solution with ultra microcrystalline structure was formed in the Al-Zr alloy. Another aluminides destroyed and only partly dissolved in Al matrix. After HPT these sizes decreased up to 10 - 20 nm and they regular distributed in ultra microcrystalline Al matrix. The hardness of these materials very high -2000-3000 GPa. According the Mossbauer spectroscopy data, RPT results to changes in the phase composition of structure constituents in the Al-Fe alloys.
