Intermetallic alloys as hydrogen getters

Optimizaton of Mo-Si-B Intermetallic Alloys

Mo-Si-B intermetallics consisting of the phases Mo3Si and Mo5SiB2, and a molybdenum solid solution (“ -Mo”), have melting points on the order of 2000 °C. These alloys have potential as oxidationresistant ultra-high-temperature structural materials. They can be designed with microstructures containing either individual -Mo particles or a continuous -Mo phase. A compilation of existing data shows...

Intermetallic Phases Examination in Cast AlSi5Cu1Mg and AlCu4Ni2Mg2 Aluminium Alloys in As-Cast and T6 Condition

Molecular Dynamics Study of Thermal Properties of Intermetallic Alloys

Molecular dynamics simulations of bulk copper, gold pure metals and their ordered intermetallics alloys of Cu3Au(L12) and CuAu3(L12) have been carried out between above 0 K and below the their melting points of the materials for predicting their temperature-dependent thermophysical properties. The effects of temperature and concentration on the physical properties such as enthalpy, volume, heat...

Givers and Not Getters

a chain of events which leads to the disintegration of the personality and ultimately to the hospital. The percentage of the population who will spend some part of their lives in a mental hospital is increasing, and 3 large proportion of these people are elderly. Senile dementia, it is thought* is accelerated by loneliness. A harsh winter makes already existing problems more imminent. Death amo...

Studies of Modified Hydrogen Storage Intermetallic Compounds Used as Fuel Cell Anodes

The possibility of substituting Pt/C with the hydrogen storage alloy MlNi3.6Co0.85Al0.3Mn0.3 as the anode active material of a proton exchange membrane fuel cell system has been analyzed. The electrochemical properties indicate that a much more electrochemically active anode is obtained by impregnating the active material loaded anode in a Nafion proton conducting polymer. Such performance impr...
