Trends in the dependences on temperature and concentration of experime
ntally determined heat capacities of liquid and undercooled liquid met
als and alloys are discussed. A new adiabatic calorimeter for determin
ing the heat capacity of liquid alloys up to 1500 K is described. The
ability of several approximations and models to describe the different
characteristics of the heat capacity of liquid and supercooled liquid
metals and alloys is demonstrated.
