The method for preparation of Zr-based bulk metallic glass-crystalline metal alloy composite and multifunctional Zr-based bulk metallic glass-crystalline metal dissimilar alloy composite thereof

摘要

The present invention relates to a method for producing a zirconium-based bulk amorphous metal-crystalline metal alloy dissimilar metal composite using a coextrusion method, and to a multifunctional zirconium-based bulk amorphous metal-crystalline metal alloy dissimilar metal composite prepared according to the present invention. The metal alloy is used as the core material, the zirconium-based bulk amorphous metal is used as the sleeve material, and the softening agent is added. The coextrusion temperature is 658-673 K, and the coextrusion rate is 10 ^-3-3 × 10 ^-2 mm. Multifunctional zirconium-based bulk amorphous metal-crystal prepared by the above method, which is a method of preparing a zirconium-based bulk amorphous metal crystalline metal alloy dissimilar metal complex and a shape in which a bulk amorphous metal is enclosed in a circle around the metal alloy It relates to a metal alloy dissimilar metal composite. The method for preparing a zirconium-based bulk amorphous metal-crystalline metal alloy dissimilar metal composite according to the present invention has a simple manufacturing process using a coextrusion method, and has an interfacial bonding property between the core material and the sleeve material at low coextrusion temperature and coextrusion rate. It is excellent, and since the strength is improved because cracks and intermetallic compounds are not produced, it can be usefully used as a high strength multifunctional composite material.;Coextrusion, Crystalline Metal Alloy, Bulk Amorphous Metal, Metal Composite
