  • The main objective of this book is to show, in a logical sequence, a set of papers presenting new ideas that have been the result of the great advance in the knowledge of steel within the last few decades. Amongst the fundamental topics dealt with is the relationship between steel's properties in terms of its structure and composition and how this is affected by its surrounding environment (i.e. stresses, temperature, strains, etc.).

  • This section presents and discusses the properties of structural steels that are of importance in design and construction. Designers should be familiar with these properties so that they can select the most economical combination of suitable steels for each application and use the materials efficiently and safely. In accordance with contemporary practice, the steels described in this section are given the names of the corresponding specifications of ASTM, 100 Barr Harbor Dr., West Conshohocken, PA, 19428.

  • Aluminum alloys also display high fatigue crack growth rate, as much as three times faster than in steel specimens when subjected to the same stress intensity (Czyryca et al 2006). Aluminum alloys are anodic to most other materials used in construction and therefore, susceptible to localized galvanic corrosion. They are also sensitive to stress corrosion cracking. Other concerns involve marine fouling since aluminum alloys cannot be coated with conventional Cu-based antifouling coatings. In summary, the U.S.

  • Michael Faraday?s early metallurgic researches, from 1818 to 1824, anticipated the developments which have led to widespread use today of alloy steels. Much effort has been expended to improve their performance for their service as cutting tools in machining. The aim has always been to yield higher rates of machining and to tackle recently developed harder materials on the principle that the tool material must be harder than the workpiece which is to be machined.

  • The chemical process industries (CPI), petroleum and allied industries apply physical as well as chemical methods to the conversion of raw feedstock materials into salable products. Because of the diversity of products, process conditions and requirements, equipment design is often unique, or case specific. The prime requirement of any piece of equipment is that it performs the function for which it was designed under the intended process operating conditions, and do so in a continuous and reliable manner.

  • Material Selection. The material systems currently in commercial use include ferrous alloys (low-alloy steel, stainless steels, soft magnetic alloys), nonferrous alloys (brass, bronze), tungsten carbide, pure nickel, electronic alloys (Invar, Kovar), and tungsten-copper composites. The physical and mechanical properties of several MIM engineering alloys (low-alloy steel and stainless steels) have been standardized by MPIF (Ref 10).
