Abstract
A modification to picric acid solutions has been undertaken to reveal the prior-austenite grain boundaries in microalloyed steels as a result of elemental segregation. It has been found the maximum addition of sodium dodecyl sulphate plus hydrochloric acid to fully reveal both the prior austenite grain boundaries and the final post-processed structures in these steels.
摘要
对苦味酸溶液进行了改良，以揭示微合金钢中由于元素偏析而导致的先共析奥氏体晶界。研究发现，最大程度地添加十二烷基硫酸钠加盐酸，可以完全揭示这些钢中的先共析奥氏体晶界和最终的后处理结构。
