... by a reduction of cross-sectional area caused by intergranular attack and slight dezincification of the inner bore surface of the fitting. Dezincification and intergranular attack were attributed to excessive exposure to nonoxidizing acids in the pickling bath. Selected Reference Selected Reference...

..., this choice also has its drawbacks. Although it has high tensile strength, it has low resistance to nonoxidizing acids, [ 14 ]. Furthermore, high nickel-chromium alloys (such as Inconel) show poor resistance to liquid tin at 300 and 600°C. Nickel-chromium steels suffer rupture failures when stressed...

... those chemical and physical properties that make them applicable for structures, or as components of systems, that are exposed to environments above 538 °C (1000 °F).” Nowadays, refractories are made of not only oxides and nonoxide compounds (carbides, nitrides, and carbons), but also of metallic...

... are described in more detail in Corrosion , Volume 13 of the ASM Handbook. However, as a brief introduction, the electrochemical nature of corrosion can be illustrated by the attack on zinc by hydrochloric acid. When zinc is placed in dilute hydrochloric acid, a vigorous reaction occurs; hydrogen gas...

..., and the application of preventive measures. The fundamentals of corrosion are described in more detail in Ref 2 . However, as a brief introduction, the electrochemical nature of corrosion can be illustrated by the attack on zinc by hydrochloric acid (HCl).

... or melts are deficient in the oxide ion concentration, leading to acidic fluxing that results in pitting attack. Sulfides are found in the pitted area ( Ref 25 ). Low-temperature hot corrosion may involve a gaseous reaction of SO 3 or SO 2 with CoO and NiO, which results in pitting from the formation...

.... For example, an acid-containing vapor stream may not be corrosive above its dewpoint, but if the stream is cooled below its dewpoint, severe general attack can result from acid condensation on internal surfaces of tube walls. A calculation of the dewpoint when the unit operates at higher-than-atmospheric...

.... From 1970 to 1974, a series of studies was performed on the LME of iron ( Ref 28 , 29 , 30 , 31 ). These tests were made under nonoxidizing conditions using notched tensile-creep test specimens. A thin copper coating (8.5 μm thick) was plated onto the notched surface using a cyanide bath. The amount...

The debris formed by many nonferrous metals is largely unoxidized and is larger in particle size than ferrous materials are. If fretting occurs in an inert or protective atmosphere, little debris is produced. The general...
