Pacific Northwest National Laboratory has reported that researchers there have created a tough new alloy that has potential use in advanced nuclear reactors and that is not dependent on a difficult-to-get element. The research team, which included materials scientists Isabella van Rooyen, Subhashish Meher, and Steven Livers, started its experiments with the highly durable nickel-chromium-cobalt-molybdenum “super alloy” known as Inconel 617 (IN617).
