In order to better understand the formation of the lattice defects during the melting process , and the tensile deformation mechanism of the SLM-produced Co29Cr9W3Cu samples , the microstructures of the samples before and after tensile deformation were observed using a scanning electron microscope ( SEM ) , a transmission electron microscope ( TEM ) , and an electron back-scattered diffraction ( EBSD ) , respectively .
