Description

technical field [0001] The invention belongs to the field of preparation of inorganic metal compounds, in particular to a high wear-resistant dual-phase metal compound Al x Ce y CuFeNiMn p o q Zr and its preparation method. Background technique [0002] Metal compound (or called inorganic metal compound) refers to the combination of various elements in the compound according to a certain stoichiometric ratio, and the crystal structure of the formed metal compound is completely different from the crystal structure type of the constituent elements. Usually metal The crystal structure of the compound is relatively complex, and the typical feature is that the crystal structure type of the metal compound is different from any component, and its composition can be expressed by a chemical formula, not a composition. Metal compounds are important constituent phases of many alloys. When metal compounds appear in traditional alloys, the hardness and wear resistance of the alloy c...
