Abstract: Abstract Young's, shear and bulk moduli of Ce1-xSmxO2-x/2 (x ≤ 0.55) were studied using ultrasonic time of flight and nanoindentation techniques. Sound velocity measurements, corrected for sample porosity, demonstrate decrease in the unrelaxed ceramic moduli with increasing… read more here.
