... mechanical property test for quality-assurance purposes. Thus, tensile testing often is specified as the mechanical property test for heat treated aluminum products, because the correlation between hardness and either tensile strength or yield strength of aluminum alloy is not as good as it is for steels...

Perhaps the most prevalent use of the flux leakage method is widely used to inspect ferromagnetic tubular products, such as gas pipelines, down hole casing, and a variety of other forms of steel piping. The technique is highly developed for use in petroleum-industry...

For many years, traditional wet chemical methods of analysis ( Ref 1 , 2 ) were the most common, most precise, and often the only methods available for obtaining the chemical composition of ceramic materials. The technological development of instrumental methods of analysis has been...

A major problem with this test method occurs when corrosion products form in the crack, blocking the crack mouth and interfering with the environment at this crack tip. Moreover, the oxide can wedge open the crack...
