NON-DESTRUCTIVE HOT MODULUSOF CERAMICS, GLASSES, METALS, ALLOYS AND COMPOSITES Need to know the stiffness and damping properties of your high-temperature-resistant material? From only one non-destructive DMA test, you can obtain a complete characterization across a broad temperature range. The main application fields for DMA tests to 1500°C are: ■ Aeronautics ■ Energy generation ■ Transportation The new DMA GABO EPLEXOR® HT series by NETZSCH offers the technique: DYNAMIC-MECHANICAL ANALYSIS TO 1500°C The DMA GABO EPLEXOR® HT series features unrivaled technology backed by more than 40 years...

Dynamic-Mechanical Analysis Principle DMA/DMTA Results During a dynamic-mechanical (DMA) test, a sinusoidal force (stress, σ) with a certain frequency is applied to a sample (Fig. 1). The result is a sinusoidal deformation (strain, ε) as a material response (fig. 2). The delay between the excitation and response is called phase shift (δ). Theoretically, it exhibits a value of 0° for fully elastic samples and a value of 90° for completely viscous substances. In fact, the phase shift of most materials is somewhere in between 0° and 90°, depending on the elastic and viscous proportions....

DMA GABO EPLEXOR® HT Series UNIQUE SYSTEMS The DMA GABO EPLEXOR® HT series comprises the only DMA instruments on the market which are able to perform measurements in the high-temperature field!

FOR DYNAMIC TESTS TO 1500°C Rigid Design High temperatures make high demands on the flexural strength of the set-up within the hot temperature zone. DMA GABO EPLEXOR® HT instruments are equipped with sample holders made of sintered silicon carbide (SSiC), a dense and stiff ceramic which upholds this property even at 1500°C. All Set for Future Changes Due to its modular design, the DMA GABO EPLEXOR® HT series allows for easy upgrading of the system with a variety of force sensors as well as different furnaces, depending on the application range. Broadest Temperature Range By combining the...

Extraordinary Performance Based on an Elaborated Conceptual Design Maximum Flexibility Extended Force Range Through Independent Drives The DMA GABO EPLEXOR® HT series is an instrument line for all kinds of mechanical measurements. Dynamic-mechanical standard parameters (tanδ, E’, E’’, etc.) can be determined and creep, relaxation or fatigue tests can be carried out. Static and dynamic force transducers can be actuated independently. The static force is realized by a servo motor; the dynamic force is generated by an electrodynamic shaker system. This allows the application of a dynamic force...

Applications Bending Test on Bauxite* Bauxite is an aluminum ore and the basis for the production of metallic aluminum. DMA instruments are not specifically engineered to handle destructive experiments. However, if such an event were to occur, the unique blade spring system in the DMA GABO EPLEXOR® HT series does offer the greatest possible degree of safety. Universal test on bauxite; 3-point bending mode; isothermal temperature: 800°C; static force: up to 500 N. The static force is shown in red; the deflection of the sample is shown in blue. * Both measurements were provided by Fraunhofer...

Bending and Softening of an Al2O3/Metal Compound* Heating a ceramic/metal compound with Al2O3 as the ceramic component in the 3-point bending mode to 1450°C results in heavy deformation of the sample. Between RT and 1250/1300°C, a bending of about 2 mm takes place, which corresponds to a static strain of approx. 40% (relative to the original specimen height). At about 1400°C (extrapolated onset temperature), the bending becomes even more pronounced. This is due to softening of the sample resulting from the melting phase of the included metal. DMA test on Al2O3 + metal; 3-point bending mode;...
