Micro Materials Ltd
United Kingdom
Registrace 27. 01. 2011
In 2018 Micro Materials Ltd celebrated 30 years of providing innovative, versatile nanomechanical test instrumentation (nanoindenter and microindenter).
Established in 1988, Micro Materials has continually been at the forefront of innovation, with our pioneering approach leading to three world firsts
• The first commercial high temperature nanoindentation stage, capable of reaching temperatures up to 1000°C.
• The first commercial nanoscale impact tester, for erosive wear, toughness and contact fatigue.
• The first liquid cell, allowing the testing of samples which are fully immersed in a fluid.
The Company offer a range of instruments including the Vantage Alpha (cost effective nanoindenter or microindenter), the Xtreme (for elevated temperature nanoindentation testing under vacuum conditions) and the flagship Vantage model, a truly innovative nanoindenter. The Vantage can also be configured as a microindenter.
Nanoindentation at impact rates - Dr Jon Molina-Aldareguia
The nano-impact test is a technique for high strain rate mechanical characterization of materials at the nano/microscale. However, its use has been limited so far because the dynamic hardness has traditionally been computed using an energy-based approach.
This work overcomes this limitation by instrumenting the test device with force-sensing capability by means of a piezoelectric load cell. The methodology was evaluated on six materials covering a wide spectrum of mechanical behaviour.
The work shows that the energy-based approach used so far yields significant errors on the determination of dynamic hardness, explaining contradictory results existing in literature, and identifies the main sources of error with the aid of finite element simulations.
In parallel, a FEM-based inverse analysis methodology was devised to transform the direct outputs of the combined nanoindentation and nano-impact tests into material parameters needed to calibrate the rate-dependent constitutive behaviour of a wide range of materials.
During this talk, Dr Molina will show:
• How to use the new instrumentation to obtain load-displacement curves at high strain rate.
• How to use this new capability to study strain rate dependent phenomena at the microscale

When a material is subjected to solid particle erosion the surface is impacted by particles at random locations and the subsequent wear is complicated by the interactions between the impact-damaged regions. Micro Materials have developed a completely new impact test technique which enables real erosion conditions to be accurately simulated by programmed stage movement that produces multiple nan...
