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…
Cold dwell behaviour of TiAl alloy: Understanding load shedding using digital image correlation and crystal plasticity simulations
Yi Xiong, Nicolo Grilli, Phani S. Karamched +3
Digital image correlation (DIC) and crystal plasticity simulation were utilised to study cold dwell behaviour in a coarse grain Ti-6Al alloy at 3 different temperatures up to 230 C…
High resolution electron backscatter diffraction study on the heterogeneities of tetragonal distortion in Fe-C martensite at the microstructural scale
Tomohito Tanaka, Nozomu Nakamura, Angus J. Wilkinson
The spatial variation in martensite tetragonality (c/a ratio) in Fe-0.77C (wt.%) alloy was investigated by means of pattern matching of electron backscatter diffraction patterns co…
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…
On the Brittle-to-Ductile Transition of the As-cast TiVNbTa Refractory High-entropy Alloy
Robert James Scales, David Edward John Armstrong, Angus J Wilkinson +1
The fracture properties of as-cast TiVNbTa, a refractory high-entropy alloy (RHEA), were investigated using four-point bending tests from -139C to 20C under a strain-rate of 10-3 s…
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…
