In this paper, Au-Zn-Cu-Ni alloy series was take as a benchmark. Nickel element was replaced by Manganese in different ratios. The existing state and distribution law of Manganese, and the effects of the Manganese on microstructure and properties of gold alloys were studied. The mechanism of effects of Manganese on the colour and the release of nickel of gold alloys were discussed.

Addition of small amounts of erbium has a profound effect on recrystallization and grain growth in titanium. Erbium, because of its negligible solubility in titanium, precipitates in the titanium matrix as a finely dispersed second phase. The presence of this phase, depending on its average size, distribution, and volume fraction in titanium, strongly inhibits the migration of grain boundaries during recrystallization and grain growth, and thus produces ultimate grains of sub-micrometer dimensions. A systematic investigation has been conducted to study the isothermal grain growth in electrolytically pure titanium and titanium-erbium alloys (Er concentration ranging from 0-0.3 at.%) over the temperature range of 450 to 850°C by electron microscopy.
