Equilibrium between MB2 (M=Ti,Zr,Hf) UHTC and Ni: A thermodynamic database for the B-Hf-Ni-Ti-Zr system

► A thermodynamic database has been developed for the quinary system B-Ni-Ti-Zr-Hf. ► 30 phases have been modelled with special attention to self-consistency. ► Interaction parameters for all the binary and ternary sub-systems are included.
