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...
