Abstract (en)

A high-strength aluminum alloy has an aluminum-base matrix, ultra-fine TiB-base particles dispersed in the aluminum-base matrix and having a maximum particle diameter of 50nm, and fine TiB-base particles dispersed in the aluminum-base matrix and having a maximum particle diameter of 1.2 mu m. The aluminum-base matrix is composed of Al and Ti, the fine TiB-base particles are composed of Ti and B and free of Fe or Fe and Si, and the ultra-fine TiB-base particles are composed of Ti and B and contain Fe or Fe and Si.
