利用偏振光研究金属铀金相组织时,试样制备方法直接影响到观察时的衬度及良好表面的保持时间。现将我们所用的试样制备法介绍如下: 1.磨光在金相砂纸上由1/0磨到3/0号。为防止放射性粉末沾污或吸入人体内,磨时应戴好手套及口罩,并在手套箱内磨制。若无手套箱,可用水磨,砂纸浸于水中或在砂纸上加 The use of polarized light to study uranium metal microstructure, the sample preparation method directly affects the contrast of the observed and good surface retention time. Now we use the sample preparation method is as follows: 1 polished on the metallographic sandpaper from 1/0 mill to 3/0 number. To prevent contamination or inhalation of radioactive powder in the human body, gloves and masks should be worn and ground in a glove box. If there is no glove box, available water mill, sandpaper immersed in water or on sandpaper
