For silicon-carbide particle is disperseed in magnesium alloy uniformly, people attempt processing its distribution of change and microtexture in preparation technology and secondary deformation, but or can not solve well the problem that silicon-carbide particle is reunited.
Summary of the invention
The objective of the invention is to solve prior art and exist the consistency of silicon-carbide particle and magnesium alloy bad, the problem that causes silicon-carbide particle very easily to be reunited, and a kind of pair of size silicon-carbide particle mixing reinforced magnesium-base composite manufacture method is provided.
A kind of pair of size silicon-carbide particle mixing reinforced magnesium-base composite manufacture method, specifically finish according to the following steps: one, mix: at first the silicon-carbide particle with nanoscale silicon-carbide particle and micro-meter scale mixes, and obtains two size silicon-carbide particles; Two, stirring, ultrasonic wave are disperseed: at first under the mechanical stirring condition two size silicon-carbide particles are being put in the magnesium matrix of semi-solid state, continue to stir 4min ~ 6min after adding two size silicon-carbide particles, and intensification is heated to 700 ℃ ~ 720 ℃, obtain blend melt, then under ultrasonic wave is auxiliary, blend melt is carried out ultra-sonic dispersion, namely obtain two size silicon-carbide particle mixing reinforced magnesium based composites finally by die casting; The volume ratio of the silicon-carbide particle of the nanoscale silicon-carbide particle described in the step 1 and micro-meter scale is (5 ~ 30): 1; The magnesium matrix of the two size silicon-carbide particles described in the step 2 and semi-solid state volume ratio be 1:(2 ~ 10).
Advantage of the present invention: one, the present invention mixes the silicon-carbide particle of nanoscale silicon-carbide particle and micro-meter scale, obtain two size silicon-carbide particles, then utilizing Semi-solid Stirring to prepare matrix material in conjunction with the loose technology of excusing from death wavelength-division is dispersed in two size silicon-carbide particles in the magnesium alloy substrate (magnesium matrix of semi-solid state), can effectively solve silicon-carbide particle Uniform Dispersion hard problem in matrix, give full play to the particle reinforced effects; Two, two size silicon-carbide particle mixing reinforced magnesium based composites of the present invention's preparation are compared mechanical property with magnesium matrix significant increase.
