the high cycle fatigue and Fracture Behavior of friction stir welded aluminum alloy 2024
Key Engineering Materials, 2008Co-Authors: T S Srivatsan, Satish Vasudevan, Lisa E Park, Richard LederichAbstract:In this research paper, the cyclic stress amplitude controlled fatigue response and Fracture Behavior of an Al-Cu-Mg alloy (Aluminum Association designation 2024) is presented and discussed. The alloy was friction stir welded in the T8 temper to provide two plates one having high tensile ductility and denoted as Plate A and the other having low tensile ductility and denoted as Plate B. Test specimens of the alloy, prepared from the two plates, were cyclically deformed under stress amplitude control at two different load ratios with the primary objective of documenting the conjoint influence of magnitude of cyclic stress, load ratio and intrinsic microstructural effects on cyclic fatigue life and final Fracture characteristics. The high cycle fatigue resistance of the alloy is described in terms of maximum stress, R-ratio, and microstructural influences on strength. The final Fracture Behavior of the friction stir welded alloy is discussed in light of the concurrent and mutually interactive influences of intrinsic microstructural effects, deformation characteristics of the alloy microstructure, magnitude of cyclic stress, and resultant fatigue life.

the tensile deformation and Fracture Behavior of friction stir welded aluminum alloy 2024
Materials Science and Engineering A-structural Materials Properties Microstructure and Processing, 2007Co-Authors: T S Srivatsan, Satish Vasudevan, Lisa E ParkAbstract:In this paper, the salient intricacies of friction stir welding of aluminum alloy 2024 are highlighted. Influence of welding parameter, primarily the heat flow conduction path, on microstructural development of a 0.125 in (3 mm) thick plate of the aluminum alloy is presented. The conjoint influence of weld parameter and intrinsic microstructural features on tensile deformation and quasi-static Fracture Behavior is presented and discussed. The tensile properties and Fracture Behavior of the welded sample is compared with the unwelded counterpart. The microscopic mechanisms governing tensile or quasi-static Fracture are rationalized in light of intrinsic microstructural features of the welded sample, deformation characteristics of the alloy microstructure, and nature of loading.

the strain amplitude controlled cyclic fatigue defomation and Fracture Behavior of 7034 aluminum alloy reinforced with silicon carbide particulates
Materials Science and Engineering A-structural Materials Properties Microstructure and Processing, 2004Co-Authors: T S Srivatsan, Meslet Alhajri, W Hannon, Vijay K VasudevanAbstract:Abstract In this paper, the cyclic stress response and stress versus strain response characteristics, cyclic strain resistance and low-cycle fatigue life, and mechanisms governing the deformation and Fracture Behavior of aluminum alloy 7034 discontinuously reinforced with silicon carbide particulates are presented and discussed. Specimens of the metal–matrix composite were cyclically deformed, using fully-reversed tension–compression loading under total strain amplitude control, at both ambient and elevated temperatures for the under aged and peak aged microstructural conditions. Under fully-reversed total strain amplitude control cycling, specimens of the composite exhibited combinations of cyclic hardening and cyclic softening to failure. The cyclic stress response and stress versus strain response characteristics, cyclic strain resistance, low-cycle fatigue (LCF) life, and final Fracture Behavior of the composite, for both the under aged and peak aged microstructures, at the two temperatures, are compared and observed differences rationalized in light of the mutually interactive influences of cyclic strain amplitude and concomitant response stress, intrinsic composite microstructural effects, deformation characteristics of the composite constituents, and macroscopic aspects of Fracture.

the fatigue and final Fracture Behavior of sic particle reinforced 7034 aluminum matrix composites
Composites Part B-engineering, 2002Co-Authors: T S Srivatsan, Meslet AlhajriAbstract:Abstract In this research paper, the cyclic stress-amplitude-controlled fatigue response and Fracture Behavior of aluminum alloy 7034 discontinuously reinforced with silicon carbide particulates (SiCp) is presented. In view of the limited ambient temperature ductility, test specimens of the 7034/SiCp composite, in both the under-aged and peak-aged conditions, were cyclically deformed under stress-amplitude-control at an elevated temperature corresponding to the aging temperature of the alloy. The cyclic fatigue tests were conducted at two different load ratios with the objective of documenting the conjoint influences of intrinsic composite microstructural effects, nature of loading, and magnitude of cyclic stress amplitude on cyclic fatigue life and Fracture characteristics. The final Fracture Behavior of the composite is discussed in light of the concurrent and mutually interactive influences of composite microstructural effects, deformation characteristics of the composite constituents, nature of loading, and resultant fatigue life.

influence of silicon carbide particulate reinforcement on quasi static and cyclic fatigue Fracture Behavior of 6061 aluminum alloy composites
Materials Science and Engineering A-structural Materials Properties Microstructure and Processing, 2002Co-Authors: T S Srivatsan, Meslet Alhajri, M Petraroli, Bruce A Hotton, Paul C LamAbstract:In this paper, the quasi-static and cyclic fatigue Fracture Behavior of aluminum alloy 6061 discontinuously-reinforced with fine particulates of silicon carbide are presented and discussed. The discontinuous particulate-reinforced 6061 aluminum alloy was cyclically deformed to failure at ambient temperature under stress-amplitude controlled conditions. The influence of volume fraction of particulate reinforcement on high cycle fatigue response is presented. The underlying mechanisms governing the Fracture Behavior during quasi-static and cyclic fatigue deformation are discussed and rationalized in light of concurrent and mutually interactive influences of composite microstructural features, deformation characteristics of the metal matrix and reinforcement particulate, nature of loading and ductility of the microstructure.
