Description

technical field [0001] The invention relates to the technical field of forging lubricants for aluminum profiles, in particular to a water-based nanometer tungsten disulfide isothermal die forging lubricant for improving forging efficiency and a preparation method thereof. Background technique [0002] Isothermal die forging is a method of realizing die forging at a slower forming speed while keeping the mold and the workpiece at the same temperature. Since the workpiece is deformed at a lower strain rate at high temperature, the deformed material can be fully recrystallized, so that It overcomes the influence of work hardening, so it is very suitable for forming and processing parts with complex structure and high strength. In the process of die forging, friction will hinder the flow of metal, increase the forging load, consume deformation energy, cause uneven structure of the workpiece, dissatisfaction of the cavity filling, and reduce the service life of the die. Therefore...
