采用蔚仪试验器械制造有限公司生产的MP-2B型磨抛机,将多向锻造后的纯钼试样分别经过400#、600#、800#、1000#、1200#、1500#、2000#的金相砂纸打磨后,再采用金刚石抛光剂抛光,通过在电压为18V的5%高氯酸酒精溶液中电解抛光30 s处理后观察。EBSD分析采用带有EBSD探头的ZEISS Sigma 500场发射扫描电镜。
Using the MP-2B grinding and polishing machine produced by Weiyi Testing Equipment Manufacturing Co., Ltd., the multi-directional forged pure molybdenum samples were respectively subjected to 400#, 600#, 800#, 1000#, 1200#, 1500#, 2000# After polishing with the metallographic sandpaper, it is polished with diamond polishing agent, and it is observed after electrolytic polishing in a 5% perchlorate alcohol solution with a voltage of 18V for 30 s. EBSD analysis uses a ZEISS Sigma 500 field emission scanning electron microscope with an EBSD probe.
