In-situ SEM investigation on fracture behavior of GTD222 superalloy during tensile process at 760 °C

In-situ SEM investigation on fracture behavior of GTD222 superalloy during tensile process at 760 °C

To characterize the fracture behaviors of the selective laser melting (SLM) processed GTD222 superalloy, in-situ scanning electron microscopy (SEM) observation was conducted during 760 °C tensile deformation. The results showed that the microcracks were mainly nucleated at the grain boundary and the...
