Sumario:Some observations of the surface of polycrystalline zinc, zirconium, and zirconiumtin, with the use of an optical microscope illuminated with a laser beam, are reported. Both normal and oblique incidence of the laser beam on the surface of the specimen were employed and the micrographs obtained are compared with those produced under normal (white) light. Finally, it is shown that by illuminating with a laser beam, it is possible to reveal grain boundaries at an earlier stage of the specimen etching than by illuminating with white light. © 1990.
