The study of SCC is typically multidisciplinary, i.e. the description of the three groups of factors and their effects belong to three different technological disciplines, namely electrochemistry/corrosion, physical metallurgy and fracture mechanics. The relative importance of electrochemical, metallurgical and mechanical factors varies strongly from one material-environment system to another. 

Rifle ammunition was produced in two publicly owned plants run by the army, and reached a daily production of 3.4 million cartridges in 1918, with a total wartime production of 3,616 million pieces. In the meantime, domestic private firms supplied the army with 700 million artillery shells, 7.3 million shells for trench mortars, and 880,830 bombs for aerial use. Because the Italian chemical industry lagged behind the metallurgical and mechanical industries, in 1918 there were more cartridges and shells made than filled. ... 

As an example of the metallurgical and mechanical properties of recently manufactured heavy section components, the properties of a nozzle shell with an integrated flange for an EPR reactor (Fig. 2.3) are described. The material is RCC-M Sectionll Part 1-M2112, which is SA508 Grade 3 Class 1 type equivalent. The nozzle portion of the component is around 600mm thick, which is more than twice the thickness of conventional shells for a PWRPV. 

The author thanks all members of the Jiilich SOFC development team, the cell testing team, the FZJ metallurgical and mechanical testing group, and the FZJ central chemical laboratories, and also others from the overall FZJ SOFC team including visiting scientists, all of whom contributed in some way or another. 

Chemical, physical, electrical, electrochemical, metallurgical, and mechanical factors often affect corrosion initiation and kinetics. 

Metallurgical and mechanical treatments often are interactive with regard to producing chemical-microstructural features in aluminum alloys, such as dislocations, precipitates, and the microstructural morphology (grain size and shape). For simplicity these two effects are discussed separately.

In order for EC to develop, a favourable combination of metallurgical, mechanical and environmental variables must exist. Often, in a given situation, it is difficult to alter the metallurgical and mechanical variables contributing to EC. Hence, it may be more convenient to modify the environment and thereby reduce the likelihood of EC occurring. 

In Norway, a series of ex post-accident cost studies have been performed within the chemical, metallurgical and mechanical industries (Sklet and Mostue, 1993). When the market-pricing model was applied, average costs to the company of accidents were about 1000 euro. They were lowest in the chemical industry (800 euro) and highest in the metallurgic industry (1100 euro). Costs increased with the severity of the accident. Costs to the company for permanent disabilities and fatalities varied between 1500 and 10000 euro. Uninsured salary to the injured worker accounted for between 74 per cent and 90 per cent of the total costs for the temporary disabilities. In-plant accident costs were significantly less than 1 per cent of the salary costs. 

Physical properties usually refer to the inherent characteristics of a material. They are independent of the chemical, metallurgical, and mechanical processes, such as the density, melting temperature, heat transfer coefficient, specific heat, and electrical conductivity. These properties are usually... 

Most engineering alloys contain multiple constituent elements to achieve the desired metallurgical and mechanical properties. Superalloys Rene N6 and CSMX-IOM are composed of as many as twelve or thirteen microalloying elements to enhance their properties at elevated temperatures (Durand-Charre, 1997). These alloying elements are added for specific purposes and...
