A method for preparing a magnesium composite material; a magnesium composite material obtainable from the method according to the present invention

摘要

A method is provided for preparing a magnesium composite material, the method comprising the steps of: a. Providing: i. a graphene platelets powder; ii. a nano titanium powder (N); iii. a magnesium silicide powder; and iv. another titanium powder (M, L); b. Mixing the components i. and ii., preferably under inert atmospheric conditions, to obtain a graphene titanium conglomerate; Mixing the graphene titanium conglomerate with the components iii. and iv.; d. Processing the mixture of step c. under inert atmospheric conditions by: i. Heating the mixture up to a target temperature (Tt), wherein the target temperature (Tt) is in the range of 780 — 1050 °C, while applying a pressure (Pi) to the mixture in the range of 0 — 10 MPa; ii. Keeping the mixture at the target temperature (Tt) while applying a target pressure (Pt) to the mixture in the range of 50 — 200 MPa in order to form the magnesium composite material; and iii. Letting the temperature decrease to room temperature.
