In this work, the microstructural evolution, micro-crack formation, and mechanical anisotropy of selective laser melted (SLM) carbon-free Mar-M509 Co-based superalloy were systematically studied under different linear energy densities (LED). Observation shows that SLM possesses a fully dense structure, whereas some micro-cracks exist along building direction. The electron backscatter diffractio...

In this paper, the short-term creep behavior of the Inconel-713C superalloy after different pre-treatments including the ageing and forging processes has been studied at 850 °C. The ageing heat treatment was heating at 930 °C for 16 hours without solutioning process. The optical microscopy (OM) and the scanning electron microscopy (SEM) techniques were applied for microstructural evaluations. T...
