Evaluating the Effects of Mass and Density on the Sinterhardening Response of Different PM SteelsThe sinterhardening response of PM steels is affected by many factors, including the alloy system, the cooling rate, density, and component size. In this paper influence of mass and density on the ...

4. Relative Stability of Different Charge States and Negative-U Character Our discussion so far indicates that hydrogen is an amphoteric impurity; that is, it behaves both as a donor and as an acceptor. In silicon, as in all semiconductors that have been theoretically investigated, the energy ...
The degassing and reduction processes in the initial stages of sintering were studied for Mo and Ni-Mo alloy steels prepared from Fe-Mo prealloy powder. The green density was varied between about 7.0 and 7.6 g.cm~(-3). By sintering in dilatometer/vacuum following a standard temperature-time...
Microstructural attributes of steels affect hysteretic magnetic properties because the microstructure affects domain wall movement and pinning. Two important features are grain size and dislocation density. The consensus experimentally is that the coercivity tends to be linearly related to the inverse of the...
Analysis of x-ray reflectivity data from low-contrast polymer bilayer systems using a Fourier method X-ray reflectivity data of polymer bilayer systems have been analyzed using a Fourier method which takes into account different limits of integration inq-s... OH Seeck,ID Kaendler,M Tolan,... ...
A compositionally complex alloy was designed, consisting of equiatomic concentrations of four low-cost commodity elements (Al, Fe, Mn, and Si). The alloy was characterized using scanning electron microscopy and energy-dispersive X-ray spectroscopy. The corrosion of the AlFeMnSi alloy, as evaluated...

The design is optimised through three-dimensional multiphysics modelling, nanoparticle infiltration, and corrosion-mitigating treatments. The monolithic fuel cell stack shows a power density of 5.6 kW/L, thus, demonstrating the potential of SOFC technology for transport applications....
The amount of hydrogen accommodated in a thin sheet of palladium under stationary flux conditions was measured by two different methods: (1) from the electrical charge spent for its removal, during the discharging cycle and (2) from the ... Man-Sheng Chen,Yi-Fang Deng,Zhi-Min Chen,... ...
