TMA 402 F1/F3 Hyperion® Thermomechanical Analysis – TMA Method, Technique and Applications Analyzing & Testing

Thermomechanical Analysis (TMA) TMA Analysis Results ■ Linear thermal expansion ■ Coefficient of thermal expansion ■ Phase transition temperatures ■ Sintering temperatures ■ Shrinkage steps Glass transition temperatures Dilatometric softening points Volumetric expansion Density changes Delamination Decomposition temperature Sintering kinetics Isostrain Creep Relaxation Stress/strain curve Thermomechanical analysis (TMA) is a technique for determining the dimensional changes in solids, liquids or pasty materials as a function of temperature and/or time under a defined mechanical force (DIN...

Thermal Expansion The linear thermal expansion is an important variable for assessing the dimensional behavior of a material in response to a change in temperature. Measurement on an epoxy resin with a sample length of 6 mm in expansion mode (fused silica sample holder); 1st and 2nd heating runs at a rate of 2 K/min This plot shows the thermal expansion (dL/L0 in %) of an epoxy resin between -70°C and 270°C. In the first heating (blue curve), the onset of the glass transition (Tg) occurs at 123°C. In the second heating (red curve), the onset of Tg is slightly shifted, to 125°C. This shift...

Detects Even the Slightest Dimensional Changes The LVDT constitutes the centerpiece of the NETZSCH TMA 402 F1/F3 Hyperion®. The technology behind it is tried-and-true: Even the slightest of length changes, into the nanometer range (digital resolution of 0.125 nm), can be measured and detected. A variation of furnace options for all applications To adjust the instrument for various temperature ranges and varied atmospheres, all that needs to be done is to change the furnace. This can be carried out by the operator. Thanks to the double furnace hoist, switching to a second furnace only takes...

The force operating on the sample is generated electromagnetically. This ensures a quick response time for experiments with a changing load. A highly sensitive force sensor (digital resolution < 0.01 mN, max. force ±4 N) continuously measures the force exerted via the pushrod and readjusts it automatically. This sets the NETZSCH TMA 402 F1/F3 Hyperion® apart from other instruments which only use preset values. Displacement control From Sensitive to Stiff Materials The electronic control system allows users to set the force value in the mN-range. This enables testing even on sensitive...

Measurements in Humid Atmosphere Simulation of Environmental Influences For TMA measurements in humid atmospheres, there are two furnaces available. The water-vapor furnace covers a temperature range from room temperature to 1250°C. The furnace can be connected to a humidity generator or to a water-vapor generator which produces steam by evaporating water. The copper furnace can be used for conventional TMA measurements from -150°C to 500°C. It can be conveniently connected to a humidity generator, allowing for in-situ drying up to 500°C and a controlled humidity environment between 0°C and...

Swelling Behavior of Wood Under Humid Conditions In the hygroscopic wood moisture range, the dimensions and the volume undergo change when moisture is absorbed by swelling and when moisture is released by shrinkage. For the practical use of wood, the following are particularly important: The dimensions of dry wood in the three anatomical directions when the ambient climate changes (differential swelling, swelling coefficient). The shrinkage of wood when drying from the wet (fresh) to the normal condition (drying rate). To test the swelling behavior on beech wood, three samples were cut from...

AutoEvaluation AutoEvaluation is an intelligent software functionality exclusively offered by NETZSCH. It is a selfacting evaluatin of thermoana-lytical measurement curves that works without using pre-defined macros. This is an immense support and time saver. AutoEvaluation offers special functions for the evaluation of various materials. When testing Metals, "Metal Melting" will automatically evaluate the onset of melting. "Glass Transition and Softening" displays the onset of glass transition and the peak of softening with just one click. Measuring ceramics, sintering steps will be...
