MicroTensile Testing for Local Mechanical Properties
Microtensile testing can accurately and effectively probe the mechanical properties of materials of interest on the local level. Specimens with overall dimensions of 3 mm x 1 mm with ~0.30 mm square gage section can be extracted from microstructural areas of interest. For anisotropic cases, the micro-tensile samples may be extracted with varying orientations to characterize differences in mechanical performance.
Here is a movie of a titanium 5111 microtension experiment conducted at room temperature under quasi-static loading. The speckle-pattern is used to determine and track strain in real time. The specimen dimensions are shown below.
