RISFatigue Crack Propagation in Low-Alloy Heat-Treated Steels
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The rates of fatigue crack propagation in several heat-treated steels were determined for several alloy steels heat-treated to yield strengths in the range 70,000 to 125,000 psi. For one steel ...
The Effect of Warm Prestressing on Notch Fracture Strength
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The effect of warm prestressing at various stress levels on the notch bend fracture properties of a Ni-Mo-V steel at two levels of strength and Charpy FATT is determined. Warm prestressing ...
The Influence of Notches on Mechanical Behavior at Elevated Temperatures: Some Metallographic Observations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A metallographic study of ruptured and unruptured notch bars is reported in this paper. The alloys are Cr-Mo-V steels tested in the range 1000–1050 deg F. Crack initiation and propagation in ...
Fatigue-Crack Growth-Rate Studies of Low-Alloy Pressure-Vessel Steels
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Fatigue-crack growth rates were determined at room temperature for ASTM A302-Class B and A 508-Class 2 steels in two characteristic plate and forging directions. Tests were performed under ...
Fracture Toughness Determinations of A-302B and Ni-Mo-V Steels With Various Size Specimens
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Fracture tests were conducted on three steels obtained from heavy-section pieces over a range of test temperatures using single-edge notched (SEN) specimens under tensile loading and notched-bar ...
