在扫描电镜中采用加载样品台能进一步对金属的变形、断裂以及应力诱发相变等过程进行动态观察,这在材料科学研究中是十分重要的。评价SEM加载样品台主要应考虑以下几方面:1)负载能力(载荷大小);2)操作控制(加载速率、方向,自动或手动);3)数据测量和输出(负载、位移的指示、记录及其精度);4)加载方式(样品受力和变形的方式)。目前各国生产的商品仪器中以英国CAMBRIDGE公司的拉伸样品台较优,但它仍存
In scanning electron microscopy, loading sample stage can further observe the deformation, fracture and stress-induced transformation of metals, which is very important in material science research. Evaluation SEM loading sample stage should consider the following aspects: 1) load capacity (load size); 2) operation control (load speed, direction, automatic or manual); 3) data measurement and output (load, displacement indication, record And its accuracy); 4) loading method (sample force and deformation of the way). Current national production of goods to the British CAMBRIDGE tensile sample stage better, but it still
