A dual-phase cobalt alloy with a triple yielding phenomenon under compression test

The compressive mechanical behavior of a dual phase cobalt alloy (Al$_{14}$Co$_{41}$Cr$_{16}$Fe$_{11}$Ni$_{18}$) is reported in this communication. An uncommon triple yielding phenomenon is observed in the as-cast condition. Microstructural studies suggest that the observed behavior may be due to a stress/strain-induced martensitic phase transformation.
