Microstructural changes in a promising material for nuclear reactors can be tracked in real time during thermomechanical tests, thanks to a new microscopy technique. Afsaneh Rabiei is pictured here with the device she developed that can capture scanning electron microscopy (SEM) images in real time at temperatures up to 1,000 degrees Celsius while applying stresses as high as two gigapascal.
A new microscopy technique allows researchers to track microstructural changes in real time, even when a material is exposed to extreme heat and stress. Recently, researchers show that a stainless steel alloy called alloy 709 has potential for elevated temperature applications such as nuclear reactor structures. “Alloy 709 is exceptionally strong and resistant to damage when exposed to high temperatures for long periods of time,” says Afsaneh Rabiei, corresponding author of a paper on the new findings and a professor of mechanical and aerospace engineering atContinue reading
