摘要: The composition and/or temperature dependence of the dynamic Young's modulus for ordered B2 Co-Al, Fe-Al, and Ni-Al aluminides has been investigated using piezoelectric ultrasonic composite oscillator technique (PUCOT). measured in interval 48.49 to 52.28 atomic % Co, 50.87 60.2 Fe, 49.22 55.95 Ni Ni-Al, respectively. values Co-Al are 300 1300 K, while those other systems ambient only. data points show that is stiffer than which Ni-Al. reported herein first their kind, since none earlier. However, Fe-Al slightly higher literature.
