Metallographic Preparation of Titanium and Its Alloys
Experiments were conducted using three-step preparation procedures for titanium and its alloys. For CP titanium and alpha-titanium alloys, use of an attack-polishing agent in the third step was required to obtain good results. The experiments defined optimum surfaces for each step and operating conditions. Two-phase, α-ß alloy specimens are significantly easier to prepare than a single-phase
