Kinetic study of isothermal crystallization in amorphous Al33Ni16Zr51 produced by mechanical alloying

A non-conventional way of production has been chosen to prepare Al33Ni16Zr51 amorphous alloy: mechanical alloying which allowed the microstructure of the material to be monitored. For this type of non-equilibrium alloys, the evolution toward an equilibrium state and the crystallization kinetics were studied by differential scanning calorimetry. The crystallization processes were interpreted in terms of several theoretical models based on nucleation and growth processes.
