new etchant containing HNO 3, HF, and CrO 3 has been developed for aluminum alloys whose grain structure is normally difficult to reveal. It removes smeared metal left by polishing and shows detail in areas prone to staining. This etchant has proved highly satisfactory for both optical and scanning electron microscopy, particularly for the powder metallurgy (PM)

ASTM formula 177, a macro etchant for visual inspection of aluminum welds. It contains no hydrofluoric acid. Reagent. ASTM formula 3, the most popular general-purpose micro etchant for aluminum alloys, shows microstructure and grains. It contains hydrofluoric acid. Others. Special mixes for jet engine
The etchant composition quoted in Example 1 give similar results to those obtained in that Example when used to etch an aluminium alloy containing 4 Cu 0.6 Mg, 0.8 Si, 0.8 Mn plus various impurities. EXAMPLE 5 The acid etchant composition described in Example 2 was used to etch the aluminium alloy described in Example 1
(silicon-consuming) aluminium-silicon alloys. With a standard potential of -1.66 V, aluminium does not belong to the noble metals. However, the forma-tion of a very thin (few nm) Al 2 O 3 film makes it very inert in many substances. Therefore, Al etchants require at least compounds for dissolving Al 2 O 3 as well as for etching (or
Reagent (AKA etch) is the most popular metallographic etchant for etching aluminum alloys, except for high silicon content aluminum. It outlines all the common constituents, and with certain aluminum alloys will reveal grain size. This product is made with ACS reagent grade chemicals. The formula is listed in ASTM Standard E 407

This product is used as a micro-etchant to reveal the general structure of Pure Tantalum, Tin-Iron alloys Zinc-Cobalt alloys. When used as a macro-etch, this product can be used on almost all aluminum alloys as a good general-purpose etchant. Additionally the sample does not
aluminum alloys low in copper, the test sample is placed in hot, nearly boiling water for a few minutes. Once the sample is hot, it is removed from the water and the surface to be etched is immersed briefly in a solution of Poultons etch. (This etchant contains the following HCL, HNO3, HF, and H2O.) This acid is

The response of microstructure in high strength Al-Zn-Mg-Cu aluminum alloy 7055 to Graff Sargent etchant was investigated. It was found that grain boundaries and subgrain boundaries were easily corroded due to presence of phase, and grain boundaries were corroded more rapidly than subgrain boundaries. The grain structure could be revealed quite clearly after immersion for
However, if the etchant forms a film, as in tint etchants, then immersion must be used as swabbing will keep the film from forming. reagent reveals the grain size of certain aluminum alloys by forming a film. This will not occur if the etch is used by
