Material characterisation

Neue Materialien Fürth GmbH

Neue Materialien Fürth GmbH's in-house laboratory is outfitted with a wide range of analytical and testing equipment for the purpose of material characterization. This includes elemental analysis equipment and two universal testing machines.

ELEMENTAL ANALYSIS EQUIPMENT

We have two machines manufactured by HORIBA Jobin Yvon for conducting elemental analysis of metal powders and solid samples. These allow us to accurately measure the nitrogen/oxygen and carbon/sulphur content of different materials. The EMGA and EMIA series machines use the carrier hot gas extraction process.

For this purpose, the samples are completely melted and the gases this produces are analysed. Various standards are available for calibrating the required measuring ranges on the machines in order to perform quantitative analysis.

ZWICK UNIVERSAL TESTING MACHINE

To ascertain materials' mechanical properties, NMF GmbH uses a Z100 static material testing machine manufactured by Zwick/Roell. Using various sample holders, test instruments and load cells (2.5 to 100 kN), we conduct tests predominantly under compressive and tensile loads. In addition, we increase the scope for bespoke component testing by developing our own instruments in house.

With a convection furnace (up to 250 °C) and a three-zone tube furnace (up to 1100 °C) at our disposal, we have everything we need for high-temperature testing. To record changes in length, NMF GmbH uses both extensometers with sensors and an optical system.

GLEEBLE UNIVERSAL TESTING MACHINE

The Gleeble 3500 testing machine manufactured by US-based company DSI is a versatile product that allows us to test a huge variety of metal materials. The hydraulic drive enables a wide range of flow velocities to be attained. Rapid heating rates can also be achieved by conductive heating of the test samples. The machine concept allows flow curves that occur during compressive and tensile testing to be recorded, for example, as well as enabling complex heat treatment to be performed and the strength of the material on solidification to be measured. Models for the development of microstructures in the test samples can then be produced using quantitative metallography.
