Combustion Synthesis of Dense TiAl Intermetallic Compound by Co/Al Sintering Addition.

Effect of Mo Addition on Nanostructured Ni50Al50 Intermetallic Compound Synthesized by Mechanical Alloying

The mechanical alloying process was used to synthesize the Ni50Al50−xMox nanocrystalline intermetallic compound using pure Ni and Al elemental powder. This process was carried out in the presence of various Mo contents as a micro-alloying element for various milling times. Structural changes of powder particles during mechanical alloying were studied by X-ray diffractometry (XRD) and scanning e...

NUMERICAL SIMULATION OF COMBUSTION SYNTHESIS OF ALUMINIDE INTERMETALLIC COMPOUNDS

Combustion synthesis is a special thermophysico-chemical process applied for production of intermetallic compounds. In the present work, a reaction–diffusion numerical model was developed to analyze the combustion synthesis of aluminide intermetallics by self-propagating high-temperature synthesis process. In order to verify the reliability of the numerical model, an experimental setup was desi...

PRESSURELESS SINTERING OF B4C-NANOTiB2 NANOCOMPOSITE BY ADDITION OF Fe AND Ni AS SINTERING AIDS

B4C and its composites with TiB2 as second phase continues to be extensively used as the preferred ceramic material in military applications as armor systems for absorbing and dissipating kinetic energy from high velocity projectiles. It also exhibits a high melting point (2427 °C), and high neutron absorption cross section. Pressureless sintering of the B 4C-nanoTiB2 nanocomposite using small ...

NUMERICAL MODELING OF THE COMBUSTION SYNTHESIS OF TiAl/Al2O3 COMPOSITE VIAMICROWAVE HEATING

Abstract: Microwave processing is one of the novel methods for combustion synthesis of intermetallic compounds andcomposites. This method brings about a lot of opportunities for processing of uniquely characterized materials. In thisstudy, the combustion synthesis of TiAl/Al2O3 composite via microwave heating has been investigated by thedevelopment of a heat transfer model including a microwave...
