    • An Apparatus for Performing Microtensile Tests at Elevated Temperatures inside a Scanning Electron Microscope 

      Sim, Gi-Dong; Park, Jun-Hyub; Uchic, Michael D.; Shade, Paul A.; Lee, Soon-Bok; Vlassak, Joost J. (Elsevier, 2013)
      In this paper, we introduce an apparatus to perform microtensile tests at elevated temperatures inside a scanning electron microscope. The apparatus has a stroke of 250 μm with a displacement resolution of 10 nm and a load ...

    • High-temperature tensile behavior of freestanding Au thin films 

      Sim, Gi-dong; Vlassak, Joost J. (Elsevier BV, 2014)
      The mechanical behavior of freestanding thin sputter-deposited films of Au is studied at temperatures up to 340 °C, using tensile testing. Films tested at elevated temperatures exhibit a significant decrease in flow stress ...

    • Scanning AC Nanocalorimetry Study of Zr/B Reactive Multilayers 

      Lee, Dongwoo; Sim, Gi-dong; Xiao, Kechao; Seok Choi, Yong; Vlassak, Joost J. (American Institute of Physics, 2013)
      The reaction of Zr/B multilayers with a 50 nm modulation period has been studied using scanning AC nanocalorimetry at a heating rate of approximately \(10^3 K/s\). We describe a data reduction algorithm to determine the ...
