In addition, the presence of the [alpha]-[Al.sub.15][(Fe,Mn).sub.3][Si.sub.2] phase that does not dissolve with solution heat treatment
would explain the nearly three times higher volume fraction observed in the asquenched condition for alloy M3S compared to the base alloy M1S, similar to the observations of Elgallad .

Solution heat treatment
was applied to superalloys to alter the grain size of the alloy to improve protective oxidation behavior.
The solution heat treatment
dissolves all carbide particles and produces a uniform austenitic microstructure via quenching.
The furnaces were ordered to meet a growing need for accurately controlled diffusion and solution heat treatment
of turbine blades and nozzle guide vanes at the Aberdeen headquarters.
Therefore, the mechanical properties of 990 gold were investigated after the metal was subjected to various combinations of solution heat treatment
and quenching, age hardening, and cold working.
In the hot stamping process of aluminium alloys the sheet is heated up to near the solution heat treatment
temperature in the furnace.
(2) In the absence of P, the coarsening of eutectic Si during solution heat treatment
may occur by simultaneous dissolution of the fine particles (Oswald ripening mechanism) and collision of the nearby particles.
