The thermochemical properties of rare earth Invar alloys were inverstigated by using a high temperature calorimeter. The enthalpies were measured in two temperature ranges. 350 ~ 750K for Y2Fe14B, NaFe8.8V3.2, SmFe10V2, YFe10V2 and 550 ~ 950K for La2Fe14B, Ce2Fe14B, Nd2Fe14B, Sm2Fe14B, NdFe12-xVx (x=1.6, 2.0, 2.4, 2.8). The relationships between temperature and enthalpies as well as heat capacities were determined, influence of heat capacity with the Invar properties was analysed.
