Indentation creep studies of iron aluminide intermetallic alloy
Indentation creep behaviour of iron aluminide intermetallic (Fe–28Al–3Cr) was studied in the temperature range of 843–963 K. The hardness and the plasticity parameter were also calculated from room temperature to 1273 K. The variation of hardness with time showed that the stress exponent ðnÞ was weakly dependent on temperature. Thermal activation parameter-activation area and energy were also c...
متن کاملAlNb intermetallic alloy
This investigation was conducted to ascertain the benefits of electropolishing after mechanical polishing for electron backscattered diffraction of a Ti 2 AlNb intermetallic Ti − 21Al − 29Nb (at.%) alloy containing the orthorhombic (O) and body-centered-cubic (BCC) phases. Electropolishing was performed at − 40 ° C in 6% H 2 SO 4 methanol solution. Atomic force microscopy was used to measure th...
متن کاملExperimental and computational creep characterization of Al–Mg solid-solution alloy through instrumented indentation
Carefully designed indentation creep experiments and detailed finite-element computations were carried out in order to establish a robust and systematic method to extract creep properties accurately during indentation creep tests. Samples made from an Al–5.3mol%Mg solid-solution alloy were tested at temperatures ranging from 573 to 773K. Finite-element simulations confirmed that, for a power-la...

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...
