A series of multi-principal-component alloys were produced by electron beam melting with pendant drop melt extraction (EBM PDME) in order to expolore the effect of production mode on their structure, hydrogen storage performance and mechanical properties. Alloys ydrogenation led to formation of hydride phases accompanied by BCC to FCC transition with the lattice volume expansion close to 30%. The reveresible hydrogen capacity was of the studied alloys correspond was 1.5–1.7 wt.%. Analysis of physico-mechanical properties showed that the tensile strenght of the pristine MPC alloys reahed 1000 MPa with a relative elongation of 5%. It was also demonstated that the thermal conducitvity values are close to the stainless steels and Ti-based alloys
