Embodiment 1

[0073] The present invention proposes a high-hardness alloy, which has the characteristics of low titanium content, low cost, light weight, high hardness, high strength, high toughness, and strong plasticity: the high-hardness alloy includes the following raw materials in parts by mass:

[0074]

[0075] The balance is Al.

Embodiment 2

[0077] This embodiment is further optimized on the basis of the above-described embodiments, and further to better realize the present invention, the high-hardness alloy is prepared from raw materials containing the following parts by mass:

[0078]

[0079]

[0080] The balance is Al.

Embodiment 3

[0082] For example, the preparation method of high-hardness alloy adopts the method of loading the raw materials in two parts respectively, and adopts the optimized forging process parameters (multi-level temperature control method), so that the obtained high-hardness alloy is comparable to the titanium alloy forged on the basis of the existing process. Compared with that, the tensile strength at room temperature increased by 20.12-23.89%, the yield strength at room temperature was 22.22-24.29% higher, the tensile strength at 450°C was 21.49-22.68% higher, and its strength was 18.51-19.87% higher; and effectively improved To ensure the Vickers hardness and impact toughness of the high-hardness alloy obtained by smelting, the preparation method of the high-hardness alloy comprises the following steps:

[0083] 1) Ingredients: 8-24 parts by mass of Ti powder, 2-5 parts by mass of Cu powder, 2.5-3.5 parts by mass of Mg powder, 0.3-0.8 parts by mass of Ta powder, 8-14 parts by mass...

Abstract

The invention discloses a high-hardness alloy, a preparation method, machining equipment of the high-hardness alloy for manufacturing a fastener and a method. Ti powder, Cu powder, Mg powder, Ta powder, Cr powder, Mo powder, Fe powder, V powder and Al powder are taken to smelted and forged in a multi-section temperature control machining mode and a modified machining mode to obtain the high-hardness alloy; the machining equipment, composed of an intelligent control circuit, a machining equipment set and quality testing equipment, of the high-hardness alloy for manufacturing the fastener is utilized for adopting the method for manufacturing the fastener through the machining equipment of the high-hardness alloy for manufacturing the fastener; and the high-hardness alloy is machined into the thread slotted self-locking nut fastener in an intelligent and automatic mode, and the fastener obtained through machining has the characteristics of high hardness, good toughness, high strength and the like.

Description

technical field [0001] The invention relates to the fields of alloy technology, alloy processing technology, fastener production and processing technology, etc., specifically, high-hardness alloy and its preparation method, and its processing equipment and method for manufacturing fasteners. Background technique [0002] Alloys are substances with metallic properties that are synthesized by two or more metals and metals or nonmetals by a certain method. It is generally obtained by melting into a homogeneous liquid and solidifying. According to the number of constituent elements, it can be divided into binary alloys, ternary alloys and multi-element alloys. [0003] The production of alloys by humans began with the production of bronzes. The earliest alloys produced in the world were the ancient Babylonians. Six thousand years ago, the ancient Babylonians had begun to refine bronze (the alloy of red copper and tin). China is also one of the earliest countries in the world t...
