抄録

Measurements of rigidity modulus, thermal expansion, magnetization at 293∼573 K and hardness at room temperature have been carried out for annealed Mn-Ga alloys.<BR>The results show that Mn-21.0∼26.8 at%Ga alloys of the ε phase and the β+ε phase cooled slowly from 1173 K have distinct anomalies at the temperatures corresponding to the Néel points in both the rigidity modulus vs temperature curves and the thermal expansion curves. Thus the rigidity modulus curves exhibit a small maximum below the Néel point TN, showing a typical Elinvar characteristic near room temperature. The thermal expansion coefficient becomes smaller below TN.
