Additional alloying elements - La,Mg,Co,Nb,Cr,Ti. Objective of research was to establich influence of chemical compound of multicomponent Zr- and Al-based alloys on super-cooling, thermal stability, dependences of solid-phase transformation in wide temperature region and to establish their thermodynamic characteristics and physical and mechanical properties. Used methods: differential analysis, thermo gravimetric analysis, dynamic mechanical analysis, differential scan calorimetry, chemical analysis, xray analysis, optical microscopy, etc. Phase diagrams of multicomponent Al-bases alloys were developed. Solid-phase transformation feature was determined. Conditions of nanostructure formation were established. Detected that processes of relaxation in amorphous alloys beginning at temperature less than glassing temperature (Tg), and processes of phases formation at heating have diffusion nature. On the base both thermodynamic characteristics and experimental results the alloys with big ability to bulk amorphicity were detected. An thermofixation effect of samples shape some Al-bases alloys was established. Thermodynamic characteristics (T1,Ts,Tg,Tx,Ea) and physical and mechanical properties ( , HV, , , E) of alloys with big ability to bulk amorphicity were detected.
