摘要:
A method of preparing a crystalline or amorphous material, wherein a droplet of a melt of a metal-containing material is cooled in the atmosphere of an inert gas or in vacuum and in a microgravity environment to solidify the droplet. The cooling is performed by impingement of the droplet prior to solidification against a cooling surface.
摘要:
A method of preparing a magnetostrictive material, including the steps of: (a) forming a melt of metals having a composition corresponding to the magnetostrictive material; (b) subjecting the melt to a micro-gravity environment; and (c) cooling the melt in the micro-gravity environment at a rate of at least 50° C. per second, while applying a magnetic field to the melt, to solidity the melt.
摘要:
A method of fabricating a crystal thin plate of a substance capable of forming a crystal, wherein a molten layer of the substance formed on a support is cooled in the atmosphere of an inert gas or in vacuum at a rate of 10-300° C. per second under a micro-gravity environment to solidify and crystallize the molten layer. The cooling is performed by contacting a portion of the support with a cooling medium.
