Stress corrosion cracking is a failure mechanism that is caused by environment, susceptible material, and tensile stress.  Temperature is a significant environmental factor affecting cracking. For stress corrosion cracking to occur all three conditions

5xxx Series. The major alloying element is Magnesium an when it is used as a major alloying element or with manganese, the result is a moderate-to-high-strength work-hardenable alloy. Magnesium is considerably more effective than

Materials Alpha alloys commonly have creep resistance superior to beta alloys.  Alpha alloys are suitable for somewhat elevated temperature applications.  They are also sometimes used for cryogenic applications.  Alpha alloys have adequate strength, toughness, and

Materials The density of Titanium is roughly 55% that of steel.  Titanium alloys are extensively utilized for significantly loaded aerospace components.  Titanium is used in applications requiring somewhat elevated temperatures .  The good corrosion

There are a large number of stainless steels produced.  Corrosion resistance, physical properties, and mechanical properties are generally among the properties considered when selecting stainless steel for an application.  A more detailed list of

Stainless Steels are iron-base alloys containing Chromium.  Stainless steels usually contain less than 30% Cr and more than 50% Fe. They attain their stainless characteristics because of the formation of an invisible and adherent

Steel Alloys can be divided into five groups Carbon Steels High Strength Low Alloy Steels Quenched and Tempered Steels Heat Treatable Low Alloy Steels Chromium-Molybdenum Steels Steels are readily available in various product forms.  

Generally, most alloying elements (excluding cobalt) delay the formation of softer microstructures and allow the higher hardness structure (martensite) to form at lower temperatures or at slower cooling rates. The alloying elements inhibit the formation
