Aluminium and magnesium matrix composites are attractive lightweight materials with strength surpassing that of the corresponding metals. Recent years have seen extensive research aimed at finding ways to control structure metal obtaining new sets properties. This review aims show field-assisted sintering is a promising approach for powder metallurgy processing aluminium composites. The focuses...

Molybdenum alloys are excellent candidates for extremely high temperature environments, such as in nuclear thermal propulsion spaceflight systems. Spark plasma sintering is a useful manufacturing technique that allows rapid fabrication of refractory materials difficult to sinter using more traditional methods. Pre-alloyed molybdenum with 30 wt% tungsten powder was consolidated spark under varie...

Despite the growing interest in spark plasma sintering (SPS) of uranium dioxide, its mechanisms have yet to be studied great detail. Herein we propose a direct method calculate apparent activation energy for densification, Qact, and stress exponent, n, SPS nearly stoichiometric UO2. A set experiments performed at different heating rates (CHR) pressures levels allowed us Qact respectively, thoug...

Spark plasma sintering (SPS) techniques have been intensively investigated for manufacturing of diverse materials. Numerous methods researched to achieve a reduction the time, larger scale production, and significant energy savings. Usually, traditional SPS need prohibitively high outputs fabricate transparent ceramics. Previous studies showed that input power can be significantly decreased whe...

An analysis of the shape memory effect a NiTi alloy by using spark plasma sintering approach has been carried out. Spark Ti50Ni50 powder (20–63 µm) at temperature 900 °C produced specimens showing good effects. However, sample showed 2.5% porosity due to load 48 MPa. Furthermore, an apparent was recorded and were characterized uniformity in chemical composition alloys significant austenite phas...
