Abstract:
1. A method for making a magnesium-based composite material, the method comprises the steps of: S10, making a semi-solid-state magnesium-based material with a predetermined viscosity capable of absorbing at least one nanoscale reinforcement uniformly within the semi-solid magnesium-base material; S20, dispersing the at least one nanoscale reinforcement uniformly into the semi-solid-state magnesium-based material; S20.1, assisting absorption of the at least one nanoscale reinforcement into the semi-solid-state magnesium-based material by stirring the semi-solid-state mixture at a controlled speed during the dispersing; S20.2, obtaining a semi-solid-state mixture of the at least one nanoscale reinforcement uniformly dispersed in and completely absorbed by the semi-solid-state magnesium-based material; S30, heating the semi-solid-state mixture to a liquid-state mixture; S40, ultrasonically processing the liquid-state mixture; and S50, cooling the liquid-state mixture.
