Novel imaging strategies in the scanning electron microscope aimed at significantly improved image contrast of second phases metal alloys are described. These include use low accelerating voltages, small working distances, and a novel detection system. Contrast is assessed as function voltage optimized conditions which result much quality presented. applied to two precipitation hardened Ni-base alloys, cast single crystal hot isostatically pressed sample.
