In the late 19070’s, there began a growing interest in rapid solidification techniques as a non-equilibrium method to produce unique, metastable materials. However, with few commercially viable applications, research in the field slowed after the turn of the century. Presently, the additive manufacture of metals is a commercially scalable method to produce bulk quantities of net-shape, metastable alloys. This non-equilibrium process opens new possibilities to design alloys specifically tailored for additive manufacturing, drawing from a trove of unexploited, rapid solidification research. In the current work, we will attempt to connect the dots from rapid solidification to developing a “printable” material, and present the microstructure and mechanical properties of several aluminum alloys designed specifically for additive manufacturing. We will also present the successful development of a high-performance aluminum alloy (Addalloy™) for additive manufacturing, utilizing this concept.
