Integration of Basic Materials Research Into the Design of Cast Components by a Multi-Scale Methodology
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We present a formal methodology to integrate basic materials research results into a design procedure for engineering components. Although the methodology is generic, we demonstrate its development ...
A Methodology for Predicting Variability in Microstructurally Short Fatigue Crack Growth Rates
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A finite element model, which implements single crystal constitutive relationships, was used to simulate fatigue cracks growing at the microstructural level. Plastic deformation (slip) was allowed ...
Instrumented Microindentation of Nanoporous Alumina Films
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We examine the mechanical behavior of anodic alumina thin films with organized nanometer-scale porosity. The cylindrical pores in the alumina film are arranged perpendicular to the film thickness ...
The Influence of Aging on Critical Transformation Stress Levels and Martensite Start Temperatures in NiTi: Part II—Discussion of Experimental Results
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An experimental study was performed to determine the effect of aging on martensitic transformations in NiTi, Polycrystalline and single crystal NiTi ([100], [110], and [111] orientations) were ...
Tetragonal Phase Transformation in Gold Nanowires
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: First principle, tight binding, and semi-empirical embedded atom calculations are used to investigate a tetragonal phase transformation in gold nanowires. As wire diameter is decreased, tight ...
Micro and Macro Deformation of Single Crystal NiTi
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We present experimental results on the instrumented Vickers micro-indentation and compression of solutionized Ni-rich NiTi single crystals. The tests are conducted at room temperature where the ...
The Influence of Aging on Critical Transformation Stress Levels and Martensite Start Temperatures in NiTi: Part I—Aged Microstructure and Micro-Mechanical Modeling
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Transmission electron microscopy is used to determine the microstructures of a Ti-50.8 at% Ni alloy given different aging treatments. Two different peak-aging treatments are shown to result in ...
Structural Engineering with NiTi . II: Mechanical Behavior and Scaling
Publisher: American Society of Civil Engineers
Abstract: This paper continues to address the overarching goal to provide a more unified understanding of
Structural Engineering with NiTi . I: Basic Materials Characterization
Publisher: American Society of Civil Engineers
Abstract: The overarching goal of this two-part paper is to provide a more unified understanding of
