A Finite Volume Framework for the Simulation of Additive Friction Stir Deposition
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this study, a finite volume simulation framework was developed, validated, and employed for the first time in a new solid-state additive manufacturing and repair process, Additive Friction Stir Deposition (AFSD). The ...
Plasticity and Fracture Modeling/Experimental Study of a Porous Metal Under Various Strain Rates, Temperatures, and Stress States
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A microstructurebased internal state variable (ISV) plasticitydamage model was used to model the mechanical behavior of a porous FC0205 steel alloy that was procured via a powder metal (PM) process. Because the porosity ...
Evaluation of Microstructure and Mechanical Properties of Al-Zn-Mg-Cu Alloy Repaired via Additive Friction Stir Deposition
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A novel solid-state additive manufacturing (AM) process, additive friction stir deposition (AFS-D), provides a new pathway for additively repairing damaged nonweldable aerospace materials that are susceptible to induced ...
Effect of Post-Deposition Heat Treatment on the Mechanical Behavior and Deformation Mechanisms of a Solid-State Additively Manufactured Al–Mg–Si Alloy
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The effects of post-deposition heat treatment on the fatigue behavior of AA6061 processed by additive friction stir deposition (AFSD) were investigated for the first time in this work. A heat treatment to recover the T6 ...
Stress-State, Temperature, and Strain Rate Dependence of Vintage ASTM A7 Steel
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The structure–property relationships of a vintage ASTM A7 steel is quantified in terms of stress state, temperature, and strain rate dependence. The microstructural stereology revealed primary phases to be 15.8% ± 2.6% ...
Microstructural and Mechanical Properties of a Solid-State Additive Manufactured Magnesium Alloy
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In recent years, additive manufacturing (AM) has gained prominence in rapid prototyping and production of structural components with complex geometries. Magnesium alloys, which have a strength-to-weight ratio that is ...
Strain Rate and Stress-State Dependence of Gray Cast Iron
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An investigation of the mechanical strain rate, inelastic behavior, and microstructural evolution under deformation for an as-cast pearlitic gray cast iron (GCI) is presented. A complex network of graphite, pearlite, ...
