Process for producing metal material with excellent mechanical properties.

摘要

In producing a metal material having a single-phase texture of an amorphous phase, a supercooled liquid having an amorphous composition is first prepared in a melting manner within a large-diameter pipe portion of a quartz pipe. Then, the supercooled liquid is converted into another form by allowing it to flow into a small-diameter pipe portion. The form conversion causes the temperature of the supercooled liquid to rise, so that the temperature of the supercooled liquid is uniformalized by this temperature-increase effect, thereby inhibiting the production of non-uniform crystal nuclei. Thereafter, the quartz pipe with the supercooled liquid contained therein is placed into a water bath, where the supercooled liquid is cooled by water and solidified. <IMAGE>
