EARLY ACTION (EA) I AND II. In this non-binding application program, a student usually applies EA I on or before the first of November (sometimes Nov. 15) and receives an admission decision by the middle of December.
Among the metals affected by this type of corrosion are stainless steel, certain magnesium alloys, and the copper-bearing aluminum alloys. Intergranular corrosion occurs in certain grades of stainless steel when the steel is heated, as in welding. Brittleness results, causing the metal to crack near the weld. For this reason, a post-weld heat treatment is needed before reinstalling stainless steel parts that have been welded.
Corrosion and more specifically, rust, is caused by one of three general factors: 1  Process Related â whether it is the cleaning process, the metal fabrication process such as cold working, heat treating or machining or the handling process, this aspect of producing a metal part is a primary contributor of corrosion.ed Rust. Hydrated oxide Fe2O3â¢H2O. (high oxygen/water exposure). Rust from Iron (III) oxides forms due to high oxygen and water exposure resulting in red rust. 1  Red rust is the result of heavy exposure to air and moisture, combined many times with a contaminate (salt).
