Abstract
The invention relates to a preparation method of a homogeneous Zn-Bi monotectic alloy modified by nano particles and a product thereof, belonging to the technical field of monotectic alloy preparation. The invention mainly comprises the following steps of uniformly dispersing nano particles (the added nano particles can stably exist in a Zn-Bi monotectic alloy system) in a high-temperature miscible region of the Zn-Bi alloy, adding the nano particles into a melt, modifying the Zn-Bi alloy, and preparing the homogeneous Zn-Bi monotectic alloy with fine, uniform and dispersed Bi phase distributed in a matrix, wherein the main reasons are as follows: when the alloy enters an immiscible region at the beginning of the solidification process, a Bi phase can be separated out from the solution and starts to nucleate and grow; meanwhile, the nanoparticles are rapidly gathered between interfaces of growing Bi phase and Zn matrix due to the action of surface energy, and a layer of film consisting of the nanoparticles is formed around the Bi phase; in addition, the nano particles can promote the nucleation of the Bi phase as heterogeneous nucleation points, thereby further refining the Bi phase.

Technical Field

Background
Monotectic alloys, also known as immiscible alloys, have been widely used in industry as structural and functional materials, for example: al-Bi alloy or Al-Pb alloy is a good bearing and self-lubricating material, bi-Ga alloy or Cu-Pb alloy is a good superconducting material, and Zn-Bi alloy is a good electrochemical material.
However, for such alloys, there is a distinct immiscible region of the two liquid phases in the phase diagram, and when the temperature is higher than the critical temperature of the immiscible region, the two liquid phase components can be well mixed to form a single solution; when the temperature is reduced to an immiscible region, the single-phase solution becomes unstable and is influenced by nucleation, diffusion, coagulation, ostwald ripening and the like, the second phase component at the moment can grow rapidly to form large liquid drops, and the liquid drops can continue to grow through collision and finally settle under the action of gravity and form serious macro segregation, so that the application of the alloy is worthless.
Therefore, the research of preparing the second phase dispersion distribution of the coagulated tissue by a proper method is one of the most important problems in the industry.
