The ETMT 8800 multifunctional testing system from Instron is suited for testing metals and other conductive materials. Combined with a direct resistance heating system, the unit offers full reverse stress loading to 3kN and unrivalled thermo-mechanical capabilities up to 1500ºC. It is ideal for measuring mechanical and physical properties and microstructural stability under thermal pressure. Using miniature test pieces, the ETMT 8800 can achieve fatigue loading rates from 20N/sec to 1,000N/sec and heating rates up to 200ºC/sec. The test system is also designed to study thermo-mechanical fatigue properties of nickel-based superalloys, hard metals (such as tungsten carbide) and lead-free solders. It can also be used to determine the resistivity, thermal-expansion coefficients and phase transformations in materials including steels and titanium alloys.
