New tool can map nanomechanical properties of materials like multi-phase alloys

New Delhi

Scientists from International Advanced Research Centre for Powder Metallurgy and New Materials (ARCI) an autonomous institute under the Department of Science & Technology, Govt. of India in collaboration with Nanomechanics Inc., Oak Ridge, USA have jointly developed an advanced tool for mapping nano-mechanical properties of materials like multi-phase alloys, composites, and multi-layered coatings.

The tool called NanoBlitz 3D has also been found to yield excellent results on a wide range of material systems, including glass-fibre-reinforced polymer composites, dual-phase steels, softwood and shale. An important aspect of this technique is its high-throughput, with just a few hours of testing required for generating more than 10,000 data points that can be processed using machine learning (ML) algorithms.

It enables the performance of a large array, typically consisting of 1000s high-speed nano-indentation tests, wherein each indentation tests takes less than one second to measure hardness and elastic modulus of a given material. In addition, it provides capabilities to carry out advanced data analysis, such as identifying and quantifying the mechanical properties of constituent phases, features or components of multi-phase alloys, composites, multi-layered coatings and so on.

The high-speed mapping capabilities of the tool can also be used to quickly establish structure-property linkages at a micrometer length scale or higher, which can help to understand multiscale mechanics and aid in development of hierarchical materials. This, in turn, expedites the development of high-performance novel materials under an Integrated Computational Material Engineering (ICME) approach.
