Anisotropic acoustic properties of directionally solidified nickel-based superalloy DZ444
Directionally solidified nickel-based superalloy DZ444 specimens with different directions were selected. The crystal orientation and microstructure were characterized by electron back-scattered diffraction technique and so on. The longitudinal wave velocity and attenuation coefficient were analyzed...
