It should be noted that the plane-strain fracture toughness, K Ic , is approximately 10 MPa · m 1/2 , and the plot of crack-growth rate as a function of stress-intensity range has a high slope, much higher than that of high-strength aluminum alloys. Hence, the fatigue life of beryllium components...
