Abstract
The invention relates to the technical field of metal material processing, and discloses a preparation method of a composite beryllium-copper alloy wire through spray co-deposition rolling. The hard phase TiB2 is added, the grain size is regulated and controlled, the high-temperature softening-resistant temperature and the stress relaxation resistance are improved, the TiB2 powder with the size being 500-800 nm is added through spray co-deposition, the phase thermodynamic stability can be enhanced, and therefore the high-temperature softening-resistant temperature of the beryllium-copper alloy is improved. TiB2 is used as a nucleation particle, fine and uniformly dispersed crystal grains can be generated, the crystal boundary is increased, dislocation movement and slippage are hindered, and the stress relaxation resistance of the beryllium-copper alloy is further improved.
