抄録

Measurements of Young’s modulus at −150∼400°C and rigidity modulus and hardness at room temperature have been performed on Mn–Cu–Cr alloys subjected to a variety of heat treatment and cold working conditions. It is shown that a clear minimum corresponding to an antiferromagnetic Néel point appears on the Young’s modulus vs temperature curves for the ternary alloys containing about 5.0∼56.0% copper and about 0.1∼24% chromium slowly cooled after heating at 950°C for 1hr. The values of Young’s modulus at room temperature in the state of annealing are higher than those in the state of cold working or water quenching, and the difference between the two becomes pronounced with increase in manganese or chromium content. The temperature coefficient of Young’s modulus differs remarkably by annealing, cold working, water quenching and reheating after cold working or water quenching. The temperature coefficient also depends largely on composition. And the presence of large positive and negative maxima on the temperature coefficient of Young’s modulus vs composition curves indicates the appearance of the Elinvar property. The room temperature rigidity modulus and its temperature coefficient shows a variation very similar to that in Young’s modulus and its temperature coefficients with process of heat treatment, reduction ratio of cold working and composition. In general, the hardness of the ternary alloys in the states of annealing, cold working and water quenching is lower than that in the state of reheating after cold working or water quenching. It is to be noted that the corrosion and oxidation resistances of the ternary alloys are fairly large.
