The metals which may be diffused into the ceramic are such as U, Pu, Th, Cd, Be, Mg, Zr, Ti, Pb, Cr, Pt, Ir, Cu, Ag, Au, Ba, Al, and B. The ceramic may be SiO2, MgO, Al2O3, ZrO2 or ceramics based on these oxides. In the pack diffusion process the ceramic is ...
dislocations, and grain boundaries are essential in determining alloy properties. Here we present a general linear correlation between two descriptors of local electronic structures and the solute-defect interaction energies in binary alloys of body-centered-cubic (bcc) refractory metals (such as W and...
Refractory metals are defined as metals with melting points higher than 1800 °C. These are tungsten, molybdenum, chromium, tantalum, niobium, hafnium, and rhenium, as well as many compounds and alloys based thereupon. Hard materials that are included in the scope of this journal ...
and iridium. The current practical application of refractory metals is relatively widespread (though arguably for specialty application) with examples being casting molds, wire filaments, reactant vessels for corrosive materials, hard tooling, and a myriad of applications where high density is desired. ...
also may be used in making various other seals between a ceramic or ceramic-like material (including high-melting glass and glass-like) materials on the one hand and metals, especially refractory metals such as tungsten, molybdenum and alloys of tungsten and of molybdenum, on the other hand. ...
The refractory metals can be tungsten or molybdenum, or mixtures thereof, generally used in the form of a powder. Exemplary refractory powders are tungsten powders designated M-10, M-20, and M-40, available from GTE Sylvania, Towanda, PA. These powders have average particle sizes of approximat...

In the last section of this review, current theoretical approaches for predicting crystal structure stability and phase diagrams are outlined with illustrative examples. 展开 关键词: materials science aluminium alloys phase diagrams chromium alloys cobalt alloys copper alloys iron alloys manganese alloys ...
Understanding the competing modes of brittle versus ductile fracture is critical for preventing the failure of body-centered cubic (BCC) refractory metals. Despite decades of intensive investigations, the nanoscale fracture processes and associated atomi
it has been confirmed that the size of the overall granular minor component is subject to the greatest influence. The following Examples showed the same tendency. Thus, below, the explanation will be omitted for cases where the average width of the alloy phase or the compound phase formed at ...
