A DSC- and X-ray Diffraction Study of Mixtures of Aluminum with 50 wt % of Aluminum Hydrate after Plastic Deformation under High Pressure

Abstract Al + 50 wt % Al(OH)3 mixture was subjected to plastic deformation under a pressure of 1–4 GPa on an anvil-type high-pressure apparatus. The samples were characterized by the methods of differential scanning calorimetry and X-ray diffraction. The baric dependences of the enthalpy of aluminum oxidation and melting and the baric dependence of sizes of coherent scattering regions displayed the extremum points at the pressures of 1.5 and 2.5 GPa. The reasons for these features are the variations in the electron structure of aluminum and/or the mechanism of aluminum deformations at the specified pressures..
