Fundamentals of Creep in Metals and Alloys* Numerous line drawings with consistent format and units allow easy comparison of the behavior of a very wide range of materials * Transmission electron micrographs provide a direct insight in the basic microstructure of metals deforming at high temperatures * Extensive literature review of over 1000 references provide an excellent reference document, and a very balanced discussion Understanding the strength of materials at a range of temperatures is critically important to a huge number of researchers and practitioners from a wide range of fields and industry sectors including metallurgists, industrial designers, aerospace R&D personnel, and structural engineers. The most up-to date and comprehensive book in the field, Fundamentals of Creep in Metals and Alloys discusses the fundamentals of time-dependent plasticity or creep plasticity in metals, alloys and metallic compounds. This is the first book of its kind that provides broad coverage of a range of materials not just a sub-group such as metallic compounds, superalloys or crystals. As such it presents the most balanced view of creep for all materials scientists. The theory of all of these phenomena are extensively reviewed and analysed in view of an extensive bibliography that includes the most recent publications in the field. All sections of the book have undergone extensive peer review and therefore the reader can be sure they have access to the most up-to-date research, fully interrogated, from the world’s leading investigators. |

... regime is termed Stage III, or tertiary creep, and leads to fracture. Sometimes, Stage I leads directly to Stage III and an ''inflection'' is observed. Thus, care must sometimes be exercised in concluding a mechanical steady-state (ss) ...
... regimes are illustrated as a function of temperature and grain size. Five-Power-Law Creep is indicated by the ''dislocation creep'' regime bounded by diffusional creep (Coble and Nabarro-Herring) and ''dislocation glide'' at low ...
... regime. The importance of steady-state is evidenced by the empirical Monkman–Grant relationship [35]: _em00ss tf 1⁄4 kMG ð4Þ where tf is the time to rupture and kMG is a constant. A hyperbolic sine (sinh) function is often used to ...
... regimes. These plots confirm a range of steady-state stress exponent values in a variety of metals from 4 to 7 with 5 being a typical value [49]. Normalization of the stress by the shear modulus G (rather than E) and the inclusion of ...
... regime, a constant sss/E (or sss/G) will imply, at least approximately, a fixed structure. Figure 12 [6] illustrates some of the Figure 7 data, as well as additional (PLB) data on a strain-rate versus modulus-compensated stress plot ...
