Thin Film Microtensile Setup
Small load frame for very thin film tensile testing combined with DIC for strain measurements. Load cells 2.5 and 0.1N available.
A load frame for testing mechanical properties of microtensile samples at room temperature. This test setup features a load capacity of 1200 N, making it applicable for testing larger samples or stronger materials.
Micro-High Temperature Tensile Testing (Micro-HTTT ) Setup
A compact furnace and load frame experimental setup for testing mechanical properties of microscale samples at elevated temperatures. The load frame features ceramic grips that allow for testing at temperatures up to 1100°C and can be configured for testing microtensile samples as well as 3 and 4 point bending samples. The high temperature load capacity is 110 N.
Milli-High Temperature Tensile Testing (Milli-HTTT) Setup
This setup is a stroke-controlled tensile tester with a 1200N load cell for millimeter scale samples. It can be used to carry out tests at room temperature as well as high temperatures up to 1100°C. It is equipped with a gas shrouding system allowing tests to be done in inert environments.
Vacuum High Temperature Setup
Vacuum chamber 36” in diameter that houses a load frame. Load cells capable of reaching loads of 25 lbs; resistive heating enables specimen heating.
Coefficient of Thermal Expansion Testing (CTE) Setup
Non-contact technique to measure in-plane CTE as a function of temperature. Field of view roughly 2mm x 3mm with a maximum furnace temperature of 1100°C.
Microbending Fatigue Setup
Unique specimen geometry with fatigue loading via pure bending, torsion or a combination of both. Specimen is driven in resonant frequency, which is monitored to establish damage accumulation.
Vacuum Tube Furnace
The vacuum tube furnace consists of a glass tube with ID of 46mm and length of 36” to temperatures up to 1100°C. The glass tube can be put under high vacuum or backfilled with a chosen gas.
MTS Load Frame
Large MTS load frame with compression platens. Two load cells allow for either 100 kN or 500 kN maximums.
Diamond Wire Saw
The diamond wire saw is for precisely preparing section of various materials, including ceramics, metals and polymers with limited thickness of damage layer. Available wire diameters include 0.12 mm and 0.25 mm.
The automated polisher is used with a hand-held tripod mount for both small samples preparation and TEM wedge specimens. Various silicon carbide grit papers, diamond grit papers and various colloidal solutions can be used for sample surface preparation.
The optical microscope has a computer interface to capture the magnified images and do quick annotations. Magnifications include 5, 10, 20 and 50x objective lenses.
