| Title: | BULK-SOLIDIFYING HIGH MANGANESE NON-FERROMAGNETIC AMORPHOUS STEEL ALLOYS AND RELATED METHOD OF USING AND MAKING THE SAME | ||||||||||||||||||||
| Abstract: | Iron based amorphous steel alloy having a high Manganese content and being non-ferromagnetic at ambient temperature. The bulk-solidifying ferrous-based amorphous alloys are multicomponent systems that contain about 50 atomic percent iron as the major component. The remaining composition combines suitable mixtures of metalloids (Group b elements) and other elements selected mainly from manganese, chromium, and refractory metals. Various classes of non-ferromagnetic ferrous-based bulk amorphous metal alloys are obtained. One class is a high-manganese class that contains manganese and boron as the principal alloying components. Another class is a high manganese-high molybdenum class that contains manganese, molybdenum, and carbon as the principal alloying components. These bulk-solidifying amorphous alloys can be obtained in various forms and shape for various applications and utilizations. The good processability of these alloys can be attributed to the high reduced glass temperature T¿rg? (e.g., about 0.6 to 0.63) and large supercooled liquid region $g(D)T¿x? (e.g., about 50-100 °C). | ||||||||||||||||||||
