High-frequency induction heated rapid synthesis and consolidation of nanostructured Mg2Al6Ti7O25-Mg0.6Al0.8Ti1.6O5 Composite and its mechanical properties

Abstract

Nanopowders of Al2O3, TiO2 and MgO were fabricated by high energy ball milling. The simutaneous synthesis and sintering of nanostuctured Mg2Al6Ti7O25-Mg0.6Al0.8Ti1.6O5 composite was investigated by the high-frequency induction heated sintering process. A highly dense nanostructured Mg2Al6Ti7O25-Mg0.6Al0.8Ti1.6O5 composite was produced with the simultaneous application of 80 MPa pressure and a induced current within one minute. The grain sizes and mechanical properties (hardness and fracture toughness) of Mg2Al6Ti7O25-Mg0.6Al0.8Ti1.6O5 composite sintered at 1150 degrees C were investigated.
