Abstract

The work aims to characterize the effects of processing parameters on the mechanical properties of CMSX-4^® fabricated using a laser-powder bed fusion (LPBF)-based additive manufacturing (AM) process, scanning laser epitaxy (SLE). The laser power, the scan speed, and the number of repeat scans are varied in SLE. These parameters are combined to define a new measure such as the energy density. Microstructures of the samples are investigated using optical microscopy and scanning electron microscopy. Uniaxial tension tests are performed on samples in longitudinal direction and relevant data is extracted. This work is sponsored by the Office of Naval Research through grant N00014-14-1-0658.
