The maximum wavelength attained by the alloy of critical composition is smaller than the maximum observed for the 40–60 or 80-20 alloys: this was attributed to a maximum in elastic strain energy, due to coherency strains, at the critical composition. The change in wavelength growth rate with...

studied the effect of Zr content on the microstructure and properties of the dispersion strengthened Pt20Rh alloy, and found that the existence of ZrO2 particles makes the alloy have a more stable grain structure under high temperature service condition. With the increase of Zr content, its room...

calledpolyxene; it is 80 percent to 90 percent platinum, with 3 percent to 11 percentiron, plus the other platinum metals, andgold,copper, andnickel. For mineralogical properties,seenative element(table). Platinum is also found in the very rare native alloyplatiniridium. Platinum occurs ...
In previous studies on the biosynthesis of Ag-Pt nanoparticles, a large portion of these nanoparticles has been observed to have mostly core-shell and alloy in geometrical orientation. This has been attributed to the broad miscibility gap between silver and platinum [32]. For example, bimetallic ...
A number of traces of platinum were found in the gold used in hieroglyphics and ancient Egyptian tombs dating back to 1200 BC. It is believed early Egyptians did not realize there was platinum in their gold. Pre-Columbian Americans in modern-day Ecuador used platinum alloy to make artifacts....
