Abstract

The invention discloses a Ti-based block amorphous alloy with a great amorphous forming ability and a preparation method thereof. The composition of the Ti-based block amorphous alloy is shown as the following general formula: (Ti66-xZrxBe34-yFey)100-zCuz, wherein, x, y and z are atomic percentage (*100), and have the value ranges that: x is greater than or equal to 20 and smaller than or equal to 26, y is greater than 0 and smaller than or equal to 12, and z is greater than or equal to 0 and smaller than or equal to 12. The preparation method of the Ti-based block amorphous alloy consists ofthe steps of: converting the atomic percent of the components in the Ti-based block amorphous alloy into mass percent, and weighing out raw materials; mixing and melting the raw materials under vacuum or gas protection and making a master alloy ingot; melting the master alloy ingot which is then put into an oxygen-free copper die through suction casting or spray casting, thus obtaining the Ti-based block amorphous alloy. The preparation method of the invention can prepare Ti-based block amorphous alloys with a good amorphous forming ability and a low density at a low cost.

Description

technical field [0001] The invention belongs to the technical field of amorphous alloys, and in particular relates to a Ti-based bulk amorphous alloy with large amorphous forming ability and a preparation method thereof. Background technique [0002] Compared with traditional crystalline materials, amorphous alloys have many excellent mechanical properties including high strength, high specific strength and large elastic limit, and are becoming new materials with important development prospects and a new research field. Ti (titanium) alloys are widely used in civil engineering fields such as aerospace, marine engineering, automobiles, and construction because of their rich resources, high specific strength, excellent corrosion resistance, wear resistance, and high temperature oxidation resistance. Compared with crystalline titanium alloys, Ti-based bulk amorphous alloys exhibit more excellent properties, such as higher specific strength, large elastic limit, excellent corros...
