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 收稿日期: 1990-02-18      服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 徐惠彬 谭树松 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1990/V26/I2/152 1 Van Stone R H, Rizzo F J, Raisch J F.
