Abstract

The invention discloses a Zr-Ti-Cu-Ni-Be-Co bulk amorphous alloy material and its preparation method. The Zr-Ti-Cu-Ni-Be-Co bulk amorphous alloy material is composed of the following substances, by atom percentage, 38-41% of zirconium, 14-17% of titanium, 22.5-23% of beryllium, 7.5-12.5% of copper, 0-10% of nickel and 5-12.5% of cobalt. The preparation method of the Zr-Ti-Cu-Ni-Be-Co bulk amorphous alloy material comprises the following steps: a, dosing according to the above atom percentage; b, removing the surface oxide layer; c, repeatedly smelting zirconium, titanium, beryllium, copper, nickel and cobalt in argon atmosphere for five times so as to obtain mother alloy; d, putting the mother alloy into a quartz tube, vacuum-pumping the quartz tube, heating to 1000-1100 DEG C, and rapidly quenching the quartz tube into a saturated NaCl solution to form a Zr-Ti-Cu-Ni-Be-Co bulk amorphous alloy material sample. The invention has beneficial effects as follows: breaking strength of the amorphous material is raised, and mechanical properties of the material are enhanced.

Description

technical field [0001] The invention belongs to the field of amorphous alloy materials, in particular to a Zr-Ti-Cu-Ni-Be-Co bulk amorphous alloy material and a preparation method thereof. Background technique [0002] Amorphous alloys are solidified by super-quick cooling. When the alloys are solidified, the atoms are too late to arrange and crystallize in an orderly manner. This amorphous alloy has many unique properties and has been widely used due to its excellent properties and simple manufacturing process. [0003] Amorphous alloys can be divided into: zirconium-based, palladium-based, magnesium-based, iron-based, copper-based, lanthanum-based, etc. Among them, zirconium-based amorphous alloys have attracted extensive attention due to their high amorphous forming ability and unique mechanical properties. where Zr 41.25 Ti 13.75 Ni 10 Cu 12.5 Be 22.5 (The subscript is the atomic percentage of each substance) The trade name of the amorphous alloy is "Amorphous No....
