TLDR
The design of an aluminum alloy having good strength while maintaining a high resistance to fracture is discussed in this article, where the desired microstructure consists of a small volume fraction of an ultra-fine dispersion of hard particles.Abstract:
The design of an aluminum alloy having good strength while maintaining a high resistance to fracture is discussed. Theory suggests that the desired microstructure consists of a small volume fraction of an ultra-fine dispersion of hard particles. In addition to conventional heat treatments, dispersion hardened aluminum alloys have been recently produced by rapid solidification or mechanically alloying and powder metallurgy consolidation. Alloys which can serve as models for mechanistic studies of nucleation of non-coherent phases as well as the basis for a new class of engineering aluminum alloys are identified.read more
