Fig. 4. (Color online) (a) DSC results of AlxTi3-xO5 (x = 0–0.1) samples. Positive side is a result of heating process and negative side is a result of cooling process. (b) Transition temperature change with different Al doping rate. Red upper triangles are transition temperature at heating process, and blue downward triangles are transition temperature at cooling process. (c) Latent heat during transition with different Al doping rate. Red bars are absorbed heat energy, and blue bars are emitted heat energy.
