【摘要】 介绍了铝-锌单相合金定向凝固显微组织的显示方法——机械抛光和电解抛光相结合制备金相样品;先用keller’s试剂浅侵蚀,后用改型的Tucker’s试剂侵蚀.该方法简单、方便,制备试样快速、可靠.在正交偏振光下观察,显微组织清晰、层次分明.更多还原

【Abstract】 A new method to reveal the microstructure of single-phase direct-solidified Aluminium-Zinc alloy is introduced in this paper. With combination of mechanical polishing, electrolytic polishing, etching with keller’s reagent and modified Tucker’s reagent, the microstructure of Al-Zn alloy could be identified clearly under orthogonal polarized light.更多还原
