Fabrication of Fe-Al Intermetallic Foams via Organic Compounds Assisted Sintering
The influence of the addition of organic compounds, such as palmitic acid and cholesteryl myristate, on the porous structure of Fe-Al intermetallics formation has been investigated in detail in this paper. It was found that additives have a significant effect on the final porosity of the obtained sinters. Formed gaseous products from combustion play the role of the foaming agent during Fe-Al in...
متن کاملHydrogen storage properties of Ml, _,Ca,Ni, pseudobinary intermetallic compounds
The hydrogen storage properties of the pseudobinary intermetallic compounds Ml, -.Ca,Ni, (where Ml is La-rich mischmetal and x varies from 0 to 0.9) were investigated over the temperature range of 25-80°C It was found in experiment that with increasing x in Ml,_,Ca,Ni, the incubation time for its first hydrogenation shortened, the first hydrogen absorption rate accelerated, the hysteresis lower...
متن کاملGrowth behavior of Cu/Al intermetallic compounds and cracks in copper ball bonds during isothermal aging
Copper wires are increasingly used in place of gold wires for making bonded interconnections in microelectronics. There are many potential benefits for use of copper in these applications, including better electrical and mechanical properties, and lower cost. Usually, wires are bonded to aluminum contact pads. However, the growth of Cu/Al intermetallic compounds (IMC) at the wire/pad interfaces...
متن کاملX-ray Stress Measurement for Ni-Al System Intermetallic Compound Prepared by SHS- method
An X-ray diffraction technique was used to measure the residual stress in the surface of a specimen containing a coating of a NijAl intermetallic compound produced bythe SHS (Self-propagation High temperature Synthesis) method. The Ni3Al was using the coating material for spherical carbon cast iron substrate and austenite stainless steel substrate. Differences between the coefftcient of thermal...
متن کاملAN INVESTIGATION ON REACTIVE SINTERING OF NANO-CRYSTALLINE TiO2 -Al POWDER PREPARED BY MECHANICAL ALLOYING
In this research an ultra-fine grained composite structure consisting of an intermetallic matrix together with dispersed nano-sized Al2O3 obtained via mechanical activation of TiO2 and Al in a high energy ball mill and sintering of consolidated samples. Phase composition and morphology of the milled and sintered samples were evaluated by XRD and SEM techniques Thermal behavior of the powder sa...
