EMNL presents three talks and a poster at the 2015 Fall MRS Meeting in Boston, MA.
November 30, 2015
Jason gave two talks on the role of alloying in quelling stress assisted grain growth in nanocrystalline Ni and atomistic simulations of coupled deformation mechanisms in nanocrystalline metals. Bin shared his work on quantifying disparate deformation mechanisms in metallic nanolaminates using kinematic deformation metrics, and Olivia presented a poster describing her work on in situ TEM analysis of microstructural evolution during the devitrification of amorphous Ta films.

EMNL receives a SBU-BNL Seed Grant Award on “Enabling Stable Nanocrystalline Tungsten
Alloys as Plasma-facing Materials for Fusion Reactors”
June 8, 2015
This research is a collaborative project with Dr. Simerjeet Gill in the Nuclear Science and Technology Department at Brookhaven National Laboratory to apply advanced synchrotron characterization techniques to characterize the structure of nanocrystalline tungsten alloys. Atomistic simulations will be used in concert with experimental measurements to identify pathways to improve stability and radiation tolerance through

Wenbo completed his Master’s Degree at Stony Brook University in Materials Science and Engineering, and his Ph.D. research will focus on functionally-graded FeCrAl alloys for accident tolerant fuel cladding materials.
Prof. Jason Trelewicz presents invited talk at the ASM-Long Island Chapter Meeting
February 18, 2015
Jason’s talk on “Atomistic Simulations for Uncovering the Deformation Physics in Patterned Nanostructured Alloys” described our work on understanding coupled dislocation and shear transformation zone plasticity in alloy nanolaminates.
Prof. Jason Trelewicz presents an invited talk at the International Symposium on Plasticity
in Montego Bay, Jamaica.
January 7, 2015
Jason’s talk on “Enabling Tunable Deformation Mechanisms in Alloy Nanolaminates using Hierarchical Structures” discussed our work on designing hierarchical structures into nanostructured metals to improve ductility through the coupling of dislocation and shear transformation zone plasticity.
Jason’s paper with MesoScribe Technologies and Air Force Research Laboratory, “Heat
Flux Measurements in a Scramjet Combustor using Embedded Direct Write Heat Flux Sensors”,
is accepted for publication in the AIAA Journal of Propulsion and Power.
January 4, 2015
This paper describes the testing of embedded Direct Write heat flux sensors within a direct-connect gaseous hydrocarbon-fueled scramjet combustor under Mach-5 flight conditions. Fuel equivalence ratios and dynamic pressures were systematically varied while heat flux measurements were acquired by the Direct Write sensors and separate area-averaged calorimeter plugs. Heat flux trends reported from both techniques were consistent; however, Direct Write sensors enabled the detection of subtle transient phenomena not captured by calorimetry.
