Recent developments in real-time X-ray diffraction analysis in combination with infrared thermography:: application to monitoring of mechanical-activation self-propagating high-temperature synthesis (MASHS reaction) in FeAl and MoSi2 systems

The mechanical Activation Self-propagating High-temperature Synthesis (MASHS) processing is a new way to produce nanocrystalline iron aluminide or molybdenum disilicide compounds. This kind of reaction has been investigated in situ using the Time Resolved X-Ray Diffraction (TRXDR), with an X-ray synchrotron beam, coupled to an infrared thermography to follow in resolved time structure transformation and temperature evolution. With short acquisition times, it has been possible to observe several steps before obtaining compound and to reveal the mechanical activation effect versus a classical SHS process.
