| 内容記述 | The mean temperature coefficient of rigidity modulus in a temperature range of 20° to 50° of the alloys of cobalt, iron and chromium containing 50 to 90 percent of cobalt and less than 20 percent of chromium has been measured by a torsion pendulum method. The temperature coefficients of most alloys are negative, while as the concentration approaches the composition of stainless invar (C0=54%, Fe=36.5%, Cr=9.5%), the coefficient diminishes, first gradually and then rapidly, becomes zero at a certain composition and afterwards changes its sign. Then the coefficient reaches a conspicuous positive maximum (+35.9×10^<-5>) at the concentration of stainless invar. Thus, there are many alloys having zero coefficient in this ternary system. These alloys were called Co-elinvar. The foregoing results are similar to those obtained previously by the present investigators for the temperature coefficient of Young's modulus, except that in the case of rigidity modulus, the range showing positive coefficient and the position of the positive maximum are situated at the concentrations of higher cobalt and lower chromium than in the case of Young's modulus. Further, the rigidity modulus at 20° of the alloys has also been determined, with the result that the modulus shows a maximum value (9.34×10^5 kg/cm^2) in the alloy containing 50 percent of cobalt and 5 percent of chromium and a minimum (5.92×10^5 kg/cm^2) in the one containing 65 percent of cobalt and 8 percent of chromium. | |||||||||
