抄録

Measurements of Young’s modulus at 150-700 K, and thermal expansion, hardness and tensile strength at room temperature were carried out for Mn-Cu-Ti and Mn-Cu-Zr alloys subjected to various heat treatments and cold-working. Young’s medulus vs temperature curves of annealed ternary alloys in these two systems have distinct minimum and maximum, indicating the existence of the fct α\ ightleftarrowsfcc γ phase transformation. The antiferromagnetic\ ightleftarrowsparamagnetic transition occurs near the phase transformation temperature. The elinvar properties appear around the temperatures showing a minimum or a maximum of Young’s modulus. The temperature coefficient of Young’s modulus at room temperature for the ternary alloys are affected by annealing, cold-working and reheating after cold-working or controlling the alloy composition. Young’s modulus and hardness of Mn-Cu binary alloys increase with increase of the alloying element such as Ti or Zr. The tensile strength shows a maximum at 3-4% of Ti or Zr, and it decreases gradually with increase of the alloying elements. These ternary elinvar alloys “MANGALOY” have no ageing effect. Therefore, they are considered to be excellently suitable for the materials of precision instruments.
