Timing is everything: Time-resolved experiments add niche offering at CHESS
CHESS has integrated a new operating mode that empowers researchers to capture processes on the nanosecond to microsecond timescale using 100 picosecond pulses of X-rays. At this scale, researchers can investigate swift processes in their experiments, such as crack formations racing across a material or proteins folding and unfolding – minute actions occurring in the blink of an eye.
X-rays reveal microstructural fingerprints of 3D-printed alloy
The group’s paper, “Dendritic Deformation Modes in Additive Manufacturing Revealed by Operando X-Ray Diffraction,” published Oct. 10 in Nature Communications Materials. The lead author is doctoral student Adrita Dass, M.S. ’20.
Doctoral students Adrita Dass (left) and Chenxi Tian, and Atieh Moridi, assistant professor in the Sibley School of Mechanical and Aerospace Engineering, created a portable twin of their 3D-printing setup.
Using real-time data analysis to conduct next-generation synchrotron fatigue studies
What is the discovery?
The influence of Alloying on slip intermittency and the implications for dwell fatigue in titanium
Turning Heroic Efforts Into Everyday Experiments
The challenge now is to efficiently use these expensive techniques - and the enormous datasets they produce - to better understand existing problems and gain insight into new phenomena that have been previously unreachable.
CHESS has been at the heart of this explosive growth, and will now develop new, efficient experimental and data processing protocols for using these techniques.
"Drowning in Data"
Grain-scale deformation of a high entropy alloy using synchrotron high energy diffraction microscopy
CHESS user examines material under thermo-mechanical loading - with goal to develop predictive material modeling
The information gained at the beamline can help model existing materials, while also helping to tailor new materials to better withstand harsh conditions.
