Development of Measurement / Evaluation Technology to Accelerate Practical Application of Developed Materials
Measurement and evaluation technology will play a critical role in practical application of the developed materials and in multi-material structures. ISMA is engaged in technology development in connection with analysis of structural materials, etc. by using neutron and other quantum beam techniques, and analysis and evaluation of corrosion and hydrogen embrittlement behavior for application of ultra-high strength steelsheets and other advanced materials.
Development of Structural Material Analysis Technology Using Neutron and Other Quantum Beam Techniques
Use of neutron technology, which enables nondestructive analysis of the microstructure of structural materials, is a basic interdisciplinary technology that makes it possible to realize advanced performance in steel sheets, lightweight materials, CFRP, etc., and also to understand the condition of the joints and adhesive interfaces of multi-material structures. However, improvement of the accuracy of material analysis techniques and establishment of a user system that enables easy use by researchers and others are challenges that must be overcome. In this research, ISMA began to introduce new compact neutron systems at the National Institute of Advanced Science and Technology (AIST) in FY 2017, and is also constructing a network with other compact neutron facilities (Hokkaido University, RIKEN), aiming at practical application in industrial uses of neutrons.
Development of Corrosion Behavior Analysis Technology
ISMA is conducting technology development for macro- and micro-analysis of the corrosion behavior of ultra-high strength fine-grained steels containing interfaces of multiple heterogenous phases.
Development of Delayed Fracture (Hydrogen Embrittlement) Evaluation Technology
ISMA is developing evaluation and analysis technology for delayed fracture (hydrogen embrittlement) of high tensile strength sheets, taking account the plastic deformation, stresses and hydrogen amounts applied to automotive steel sheets.
