METHOD OF DETECTING CRYSTAL GRAIN OF TITANIUM AND METHOD OF MEASURING DIAMETER OF CRYSTAL GRAIN OF TITANIUM

摘要

Disclosed are a method of detecting a crystal grain of titanium and a method of measuring the diameter of a crystal grain of titanium are disclosed. The method of detecting a crystal grain of titanium according to one embodiment of the present invention includes: preparing a titanium specimen; polishing the titanium specimen; and immersing the polished titanium specimen in an etching solution so as to detect a crystal grain in the titanium specimen. The etching solution includes 100 parts by volume of water, 5 to 15 parts by volume of inorganic acid, 40 to 60 parts by volume of alcohol, and 40 to 60 parts by volume of ammonia.;COPYRIGHT KIPO 2018
