The invention belongs to the technical field of material processing, and particularly relates to a preparation method of a high-strength high-tenacity high-wearing resistance metallic material. The preparation method comprises the following specific steps of: respectively compounding raw materials of a melt mass I and a melt mass II; preparing corresponding globular alloy powder I and globular alloy powder II with an atomizing method; performing thermal treatment on the alloy powder I and the alloy powder II; and performing ball milling and powder mixing on the powder I and the powder II afterthermal treatment in different proportions, performing cold pressing, performing sintering, and performing hot extrusion shaping, so as to obtain a non-uniform configuration metallic material of which a part of or all the deposition phases are uniformly distributed in a local space. The preparation method disclosed by the invention is succinct in principle, easy to operate, safe and reliable, andcan be used for industrialized production; besides, the working efficiency is improved, materials are saved, the production cost of an enterprise is reduced, the quality is guaranteed, and the preparation method is safe and reliable, and has higher application value and higher popularization value; and the relying of resources is reduced, and a new route for sustainable development of materials is developed.
