Thermal Expansion Linear thermal expansion shows how much a material will shrink or expand during processing, whether dissimilar materials can be joined, where the phase change occurs, and where the CTE changes. Temperature/°C TMA measurement in expansion mode on an elastomer sample (NR50): Quartz glass sample holder; 2-mm sample thickness; heating rate of 5 K/min; helium atmosphere. This figure shows the thermal expansion of an NR50 elastomer specimen, between -100°C and 0°C. The glass transition temperature (Tg) was determined to be -66°C. This marks the reversible transition from a hard, relatively...

Improving Your Productivity and Workflow with Innovative User Interface Measurement Update in Passing - LED Status Bar The TMA 512 Hyperion® series provides an LED light bar that allows you to check the status of your instrument as you walk by, with different colors representing different statuses. It is reassuring to see from afar, without having to log into your PC, that your measurement is running smoothly and to be able to read instrument status notifications such as: ■ User interaction needed The integrated color display allows you to start a measurement that was previously prepared in the...

Accessories Wide Selection of Sample Holders Make the TMA 512 Hyperion® Stand Out Prepared for Future Applications – Large Variety of Easily Exchangeable Sample Holders Testing Liquids, Molten Salts or Metals Depending upon the question at hand and the geometry of the specimen, the operator has a variety of sample holders to choose from. Holding devices for expansion, penetration, and tension measurements are available, as well as pushrods and supports for analyses in 3-point bending. Accessories for the temperature range up to 1100°C are made of fused silica. For the high-temperature range,...

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...

Hydrogen Research Using H₂Secure The H₂Secure concept developed by NETZSCH features a complete solution for conducting tests in environments with varying hydrogen concentrations while providing a maximum in safety. This flexibility is achieved through a comprehensive safety protocol embedded in the system, enabling seamless performance of complex oxidationreduction cycles and precise analysis of reaction kinetics and material behavior under different conditions. Hydrogen Gas Supply Hydrogen can be supplied from an H₂ generator or H₂ cylinder and is connected to the special H2 gas inlet on the...

Force Control Force Modulation to Gain Advanced Material Insights Constant force Linear ramp Simultaneous Measurement of Force and Displacement Signal The force acting on the specimen 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 automatically readjusts it. This sets the NETZSCH TMA 512 Hyperion® apart from other instruments, which only use preset values. Rectangular pulse Rectangular modulation...

This software option allows for determination of the density and volumetric change of specimens based on the measured thermal expansion. It can be applied for solids, liquids or transitions from solid to liquid, among others. RCS allows for control of the sintering rate during a TMA measurement by delivering precise, non-linear heating profiles that optimize your materials' microstructure and densification. The temperature program of the furnace is controlled so as to achieve the predefined sintering rate for the specimen. Depending on the selected RCS mode, the furnace may no longer be heated...
