dc.description.abstractEnAn innovative new system under high pressure syntheses activated by pulsed electric current (HP-SPS) was designed and built in-house with belt type apparatus (HP-SPS-Belt). This new HP-SPS- Belt with large volume chamber is capable of reaching high pressures up to 6 GPa and temperatures until 1800 °C. This system was pressure and temperature calibrated by using different metal calibrants. To demonstrate the efficiency of this new equipment in the present work, we have successfully shown the structural γ to α phase transformation in alumina under less severe conditions than in conventional high pressure and temperature processes. Further, we have also used this new HP-SPS-Belt to fabricate shear cutter for drilling bits in an economical way of fabrication. This study shows the wide interest of our unique designed equipment for various applications in materials processing to better control their microstructure and their properties.
