Metallic alloys with multiple principal elements are promising candidates for different industrial applications, due to their new and unexpected properties. For industrial use, however, fast and reliable production routes are necessary. Metal injection molding (MIM) is known to be an efficient method to produce near net shape components ranging from mm to meter. Since the physical and chemical environments of high entropy alloy systems are fundamentally different from those of conventional alloy systems production routes must be adapted. In this contribution we present mechanical tests on Co20Cr20Fe20Mn20Ni20 at.% specimens produced by MIM. The developed feed-stock of the gas-atomized material was directly molded into tensile test specimen shaped molds. The microstructure evolution was characterized in all production steps. Differences in both the mechanical behavior and the microstructure compared to results observed on material with the same chemical composition, which was synthesized by classical metallurgical methods will be discussed in detail.
