Embodiment 1
[0027] In this example, alumina powder is used as the high melting point hard material for dispersion strengthening, and copper alloy is used to prepare copper-containing powder to make Cu-Al 2 o 3 Powder metallurgy is carried out on the prefabricated powder round billet to prepare a dense high-strength copper-based composite material billet of copper alloy dispersion-strengthened by high-melting-point hard material particles.
[0028] In this example, see figure 1 , the electromagnetic sintering device for the method of preparing high-melting-point hard material particles dispersion-strengthened copper-based composite material by liquid-phase sintering is composed of a heating and heat preservation device, an atmosphere control device and a constant magnetic field generating device 10, specifically:
[0029] The heating and heat preservation device is composed of a stainless steel furnace body 11, a crucible 5, a refractory fiber 6, a heating element 4, a temperature control...
Embodiment 2
[0034] This embodiment is basically the same as Embodiment 1, especially in that:
[0035] In this example, the copper powder and micro-alumina powder prepared in the above-mentioned Example 1 are replaced with copper powder with dispersed distribution of nano-alumina prepared by the internal oxidation method, without powder mixing, and directly pressed into a compact, and then the above-mentioned In the same liquid-phase sintering process as in Example 1, the magnetic induction intensity is controlled to 16T, the liquid-phase sintering temperature is 1100°C, and the temperature is kept at 10 hours, then a high-strength and high-conductivity copper alloy billet with nano-alumina dispersion strengthening can also be prepared. Then, various nano-alumina dispersion-strengthened copper alloy rods, pipes, plates or wires can be prepared by conventional rolling and drawing processes, and have excellent strength and electrical conductivity.
