The morphology, the size and the phases of the pow-der were examined by X-ray diffractometer, scanning electron microscopy as well as transmis-sion electron microscopy. In the pure Fe a considerable quantity of γ-phase was found in thepowder. In ZrO_2 powder, instead of stable phase, two metastable phases appeared. Key words:  laser beam      ultrafine powder      metastable phase      Received:  18 February 1990      Service E-mail this article Add to citation manager E-mail Alert RSS （） Articles by authors URL:  https://www.ams.org.cn/EN/     OR     https://www.ams.org.cn/EN/Y1990/V26/I2/152 1 Van Stone R H, Rizzo F J, Raisch J F.
