An Investigation of the Use of Ni3Al Intermetallic Compound for Fabrication of Al Matrix Composites
Fabrication and characterization of aluminum matrix composites containing different volume fractions of Ni3Al powder (5-40 Vol%) were investigated. Ni3Al powder was produced by mechanical alloying of elemental nickel and aluminum powder mixture. Al-Ni3Al composite parts were prepared using a powder metallurgy route involving two stages Al and Ni3Al powder mixtures were first compacted under 500...

متن کاملInvestigating the Joining of Ni3Al Intermetallic Compound, using Transient Liquid Phase (TLP) Method with Cu Interlayer
In this study, joining of Ni3Al intermetallic compounds using the transient liquid phase (TLP) process with Cu interlayer was investigated. The binding process was carried out in a vacuum furnace at a temperature of 1050 °C for different times of 30, 60, 90 and 120 minutes. The effect of time variation on microstructure and mechanical properties of the joint zone was investigated. The EDS analy...
متن کاملA XAFS Study on the Site Determination of Additives in the Ni3Al Intermetallic Compound
Occupied sites by dopants of Ag(O.lat%). Pd(Zat%) and Zr(OAat%) in the Ni3AI intermetallic compound are investigated by means of EXAFS analysis. It is found that Pd substitutes the Ni site and Zr substitutes the A1 site. These results are consistent with tthose of channeling enhanced microanalysis. Ag is also determined to substitute in the Ni site by EXAFS and this result supports that Ag addi...
متن کاملNUMERICAL 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...
