Method of preparing magnetostrictive material in microgravity environment |
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.
