Abstract
Provided are an anti-fatigue in-situ aluminum-based nanocomposite material for heavy-load automobile hubs and a preparation method therefor. By means of the fine adjustment of components and a forming process, in situ nano-compositing, micro-alloying and rapid compression moulding techniques are combined. That is, after the addition of Zr and B, an in-situ reaction occurs to form a nano ZrB2 ceramic reinforcement, which is distributed in aluminum crystals and crystal boundaries and bonded to a metallurgical interface kept firm with the matrix.
