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.
