This paper reports the elastic constants of the Ni-base single crystal superalloy (TMS-26) with a rafted (lamellar) structure having tetragonal symmetry. The elastic constants have been measured at room temperature with the resonance ultrasound spectroscopy method and the mode-selective electromagnetic acoustic resonance method. The value of the elastic constant C33 (250.4 GPa) is almost equal to that of c11 (252.5 GPa), which indicates that the rafted structure virtually has the elastic anisotropy of cubic system.
本文报道了具有四方对称性的筏状（层状）结构镍基单晶高温合金（TMS - 26）的弹性常数。采用共振超声光谱法和模式选择性电磁超声共振法在室温下测量了弹性常数。弹性常数C33的值（250.4吉帕）几乎等于c11的值（252.5吉帕），这表明筏状结构实际上具有立方晶系的弹性各向异性。
