Bulk Amorphous Creation Device

basic information

By pulling down the plunger, molten Zr-based metal can be injected instantly into the mold on the copper hearth, allowing for the creation of bulk amorphous alloys. Round bars of 16mm diameter × 80mm length and plates of 5mm thickness × 18mm width × 100mm length can be produced by exchanging the molds. Additionally, this device has the capability to create not only bulk amorphous alloys but also multi-metal buttons and master alloys by changing the molds, offering good operability and enabling efficient sample production.

Applications/Examples of results

**Arc Melting and Amorphous Thin Strips** The use of arc discharge for melting various metals on a water-cooled copper hearth allows for the easy creation of alloys. It is well known that amorphous thin strips can be easily obtained by rapidly cooling metals after melting them through various methods. A cooling rate of about 10^5 K/s or higher is required for the production of these amorphous thin strips, and methods such as the single-roll technique are utilized. **Bulk Amorphous Alloys** Recently, it has become possible to create bulk amorphous alloys that do not require ultra-rapid cooling (cooling rates of 0.1 to 100 K/s) and are not in thin strip form. Due to their bulk nature, these alloys are expected to lead to the development of various applications through processing and shaping. Many amorphous alloys, including Zr-based, Fe-based, Ti-based, Pd-based, Co-based, and Nd-based alloys, have been discovered to date, and further research into alloy compositions is actively being conducted.
