Abstract

It is well known that titanium and its alloys are sensitive to electrolytes and thus hydrides are commonly observed in electropolished foils. In this study, focused ion beam (FIB) milling was used to prepare thin foils of titanium and its alloys for transmission electron microscopy. The results show the following: (i) titanium hydrides were observed in pure titanium, (ii) the preparation of a bulk sample in water or acid solution resulted in the formation of more hydrides and (iii) FIB milling aids the precipitation of hydrides, but there were never any hydrides in Ti64 and Ti5553.

摘要

众所周知，钛及其合金对电解质敏感，因此在电解抛光箔中通常会观察到氢化物。在本研究中，聚焦离子束（FIB）铣削被用于制备钛及其合金的薄箔用于透射电子显微镜观察。结果表明：（i）在纯钛中观察到了氢化钛，（ii）在水或酸溶液中制备块状样品会导致形成更多的氢化物，以及（iii）FIB铣削有助于氢化物的析出，但在Ti64和Ti5553中从未有过任何氢化物。
