Macroscopic analysis of time dependent plasticity in Ti alloys
Yi Xiong, Phani S. Karamched, Chi-Toan Nguyen +4
Component failure due to cold dwell fatigue of titanium and its alloys is a long-standing problem which has significant safety and economic implications to the aviation industry. T…
Weighted ellipse fitting routine for spotty or incomplete Debye-Scherrer rings on a 2D detector
Phani S. Karamched, Yi Xiong, Chi-Toan Nguyen +3
We introduce a weighted ellipse fitting routine to measure Debye Scherrer rings acquired on 2D area detectors and demonstrate its use in strain determination. The method is relativ…
An in-situ synchrotron diffraction study of stress relaxation in titanium: Effect of temperature and oxygen on cold dwell fatigue
Yi Xiong, Phani S. Karamched, Chi-Toan Nguyen +5
There is a long-standing technological problem in which a stress dwell during cyclic loading at room temperature in Ti causes a significant fatigue life reduction. It is thought th…
Nanoindentation in multi-modal map combinations: A Correlative Approach to Local Mechanical Property Assessment
C. M. Magazzeni, H. M. Gardner, I. Howe +5
A method is presented for the registration and correlation of intrinsic property maps of materials, including data from nanoindentation hardness, Electron Back-Scattered Diffractio…
Cold Creep of Titanium: Analysis of stress relaxation using synchrotron diffraction and crystal plasticity simulations
Yi Xiong, Phani Karamched, Chi-Toan Nguyen +4
There is a long standing technological problem in which a stress dwell during cyclic loading at room temperature in Ti causes a significant fatigue life reduction. It is thought th…
Non-contact, non-destructive mapping of thermal diffusivity and surface acoustic wave speed using transient grating spectroscopy
Abdallah Reza, Cody A. Dennett, Michael P. Short +5
We present new developments of the laser-induced transient grating spectroscopy (TGS) technique that enable the measurement of large area 2D maps of thermal diffusivity and surface…
