Description

technical field

[0001] The invention relates to a device and method for preparing metal matrix composite materials. Background technique

[0002] Metal matrix composites are a new material system composed of one or more reinforcing phases with metal as the matrix. Because of this feature, the metal matrix composites can give full play to the respective advantages of each constituent phase, so that the new composites have high comprehensive mechanical properties and microstructure morphology. Metal matrix composites have been widely used in the fields of aviation, spaceflight, national defense and automobile. At present, metal matrix composites can be divided into continuously reinforced metal matrix composites and discontinuously reinforced metal matrix composites according to the morphology of the reinforced phase. Discontinuous metal matrix composites mainly include particle reinforced metal matrix composites, short fiber reinforced metal matrix composites and whisker re...
