Alemnis launches two new modules
Alemnis, the specialist in nanoindentation technology from Switzerland, announced the availability of its new High Temperature (HT) and High Dynamic (HD) modules to complement its flagship product, the Alemnis nanoindentation platform, at the ECI “Nanomechanical Testing in Materials Research and Development” conference in Albufeira, Portugal
High temperature (HT) module
Testing materials at elevated temperatures at the micron scale has been a long standing demand from the materials science community in order to perform tests at temperature conditions commonly found in industrial applications as well as to study thermally activated deformation mechanisms.
The HT module is an add on to the nanoindentation platform and extends in-situ characterization of materials to temperatures up to 600°C in vacuum. It uses two independently controlled heating loops, one for the tip and one for the sample ensuring isothermal contact and negligible thermal drift (<10nm/min) during high temperature measurements.
Since the indentation platform can be seamlessly integrated into a scanning electron microscope (SEM), this module offers unprecedented insights into the deformation behavior by staying true to the adage “seeing is believing”!
High Dynamic (HD) module
Nanomechanical testing is increasingly moving towards incorporating newer techniques to measure properties other than modulus and hardness to gain a more comprehensive understanding of mechanical deformation behavior. In line of this Alemnis has developed the high dynamic (HD) module for performing high cycle fatigue, repeated impact, and high strain rate measurements at the micron scale.
Using a recently developed technology (patent pending), the high dynamic module enables application of strains at frequencies up to 10kHz and strain rates up to 105 per second with low noise floor (10?N RMS). From a fatigue and impact testing point of view, this opens up the possibility of performing 1-10 million cycle fatigue/impact tests within a span of 20 minutes which is unique in the market. In addition, polymers and biological materials can be tested for their frequency dependent linear viscoelastic storage and loss moduli.
As for the standard nanoindentation platform, the indenter tip (pyramidal tip like Berkovich and Cube corner, flat punch, spherical, and others) can be changed to suit the material and test technique
