WebThis technique can measure the transitions of a material as thin as 10 microns. Tension probe used for the measurement of the thermal expansion and the thermal shrinkage of the sample for measuring non-self supporting specimens. It is used for the samples like thin films and fibres under tension [7]. WebMar 1, 2024 · The sample was a flake shaped cuboid with the length, width and thickness of 0.5 cm, 0.5 cm, and 0.3–1.0 mm, respectively. The thermal expansion coefficient of the sample was measured using TMA-Q 400 (TA instruments, USA) with 2 K/min heating rate under dry nitrogen atmosphere over the temperature range of 213–323 K. intent of resignation meaning
