Amorphous metal alloy powders and bulk objects and synthesis of same by solid state
decomposition reactions |
(57) Amorphous metal alloy powders are synthesized by solid state decomposition reactions.
At least one precursor compound is thermally decomposed at a temperature below the
crystallization temperature of the amorphous metal alloy to be formed. The decomposition
product comprises an intimate mixture of the elements of the alloy and, after heat-treating
if necessary, exhibits amorphous characteristics. Amorphous metal alloy shapes are
synthesized by providing an intimate mixture of the components of the amorphous alloy,
which mixture includes at least one ductile component. The mixture may be subjected
to well-known forming techniques at a temperature below the crystallization temperature
of the amorphous metal alloy to be formed. The ductile component of the mixture acts
as a binder matrix to provide strength and uniform properties to the formed object.
