Kroll’s Reagent, 250 mL

Kroll’s Reagent, 250 mL

Kroll’s Reagent (AKA Kroll’s etch) is the most popular metallographic etchant for etching titanium alloys. It reveals the structural details, and with certain titanium alloys will reveal grain boundaries. The primary alpha structure of titanium will appear white after etching. Alpha prime and acicular alpha structures will be outlined. Intergranular beta structure and beta grains…

Alpha Case, 2% HF, 500 mL

Alpha Case, 2% HF, 500 mL

Alpha Case solution contains 2% HF (hydrofluoric acid). It is an etchant for titanium, but it also works on some aluminum alloys. This product is usually used in conjunction with Kroll’s Reagent to reveal the alpha case layer of a titanium alloy. The sample is usually etched with Kroll’s Reagent first, then this solution. The…
