Fracture corrosion induced

In addition, mercury is often present in natural gas and petroleum products, both of which can be the basis of feedstock for industrial reactions. These are generally carried out with aluminium rotors or condensers, and low levels of mercury attack aluminium components, causing stress fractures. Mercury-induced corrosion on aluminium heat exchangers has resulted in at least four long-term industrial complex shutdowns in Algeria, the USA, Indonesia and Thailand. These shutdowns required costly replacements and from several weeks to several months of lost production the plants have now been equipped with mercury removal units. 

Oral corrosion of metallic restorations does not, per se, generally result in serious damage to the structure. Corrosion can result, however, in various local and systemic effects, notably the hypersensitivity and allergic reactions reported by many workers. Galvanic cells created by mixed metal couples can delay fracture healing and induce oral lesions and cancer. 

Resistance to fatigue and corrosion fatigue The resistance of titanium to fracture by fatigue, induced by imposition of rapidly reversing stresses. 

It is possible that greater porosity in shale beds could be achieved by chemical comminution of the shale. For example, the treatment of western oil shales with acid solutions might result in comminution by inducing corrosive stress fracture of the carbonate rock. Chemical engineering research in this area, as well in the elucidation of oil-rock interactions, might provide insights for new strategies for oil shale production. 

Owing to their outstanding properties, silicon carbide fiber reinforced silicon carbide matrix (SiC/SiC) composites have been specified in several applications especially in recent fusion power plant design studies and have been considered internationally in several power plant studies. These characteristics include high-temperature properties and stability, corrosion resistance, as well as low induced radioactivity, quick decay of activity, low afterheat, low atomic number, good fracture resistance and more.
