“…However, balance of mechanical properties remains Achilles heel for metallic glasses and has thus limited its structural applications. During this same period, rapid solidification processing of crystalline metallic alloys was pursued in many forms (Das and Davis, 1988;Froes and Carbonara, 1988;Schwarz and Koch, 1998;Suryanarayana et al, 2013). In 1980s and 90s, two popular forms were atomization of alloys (Lawley, 1981;Lavernia et al, 1992;Bowman et al, 1997) for powders and planar flow casting of ribbons (Carpenter and Steen, 1992;Viala et al, 1996;Lee and Hong, 1997;Lee et al, 1998).…”

Metallic materials derive their strength and ductility from their microstructural features. The general principle of alloying is not only to control the phases present in the alloys, but also how the alloying elements can help in microstructural control during the processing of materials. The overall thermodynamic framework of using free energy to explain the stability of an alloy has two significant terms, enthalpy, and entropy. Engineering alloys are processed by several far-from-equilibrium processes. During the processing, the materials are in metastable states. The metastability can also be purposely enhanced through alloy design. This paper provides a perspective on how “high enthalpy states” can be used to tailor the microstructure to overcome the conventional strength-ductility tradeoff. The emergence of new manufacturing processes also provides unique opportunities to design alloys to maximize the potential of such processes. A few illustrative examples are presented to tie the historical use of high enthalpy states and point to future opportunities. Co-development of advanced materials for disruptive new manufacturing processes can be enhanced through integrated computational materials engineering approaches.
