Fretting Stresses in Single Crystal Superalloy Turbine Blade Attachments
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Single crystal nickel base superalloy turbine blades are being utilized in rocket engine turbopumps and turbine engines because of their superior creep, stress rupture, melt resistance, and ...
A Fracture-Mechanics-Based Methodology for Fatigue Life Prediction of Single Crystal Nickel-Based Superalloys
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A comprehensive fracture-mechanics-based life prediction methodology is presented for fcc single crystal components based on the computation of stress intensity factors (SIFs), and the modeling of ...
Determination of Subsurface Hardness Gradients in Plastically Graded Materials via Surface Indentation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Graded materials with high surface hardness and ductile cores are popularly used in high performance bearing applications to resist surface wear and fatigue damage. The gradient in hardness with ...
A Review of Rolling Contact Fatigue
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Ball and rolling element bearings are perhaps the most widely used components in industrial machinery. They are used to support load and allow relative motion inherent in the mechanism to take ...
Investigation of Three-Dimensional Stress Fields and Slip Systems for fcc Single-Crystal Superalloy Notched Specimens
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Metals and their alloys, except for a few intermetallics, are inherently ductile, i.e., plastic deformation precedes fracture in these materials. Therefore, resistance to fracture is directly ...
Subsurface Stress Fields in Face-Centered-Cubic Single-Crystal Anisotropic Contacts
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Single-crystal superalloy turbine blades used in high-pressure turbomachinery are subject to conditions of high temperature, triaxial steady and alternating stresses, fretting stresses in the blade ...
