This sequence was once prepared to supply a discussion board for evaluate papers within the zone of corrosion. the purpose of those experiences is to deliver definite parts of corrosion technological know-how and know-how right into a sharp concentration. The volumes of this sequence are released nearly on a each year foundation and every includes 3 to 5 studies. The articles in every one quantity are chosen in this type of manner as to be of curiosity either to the corrosion scientists and the corrosion technologists. there's, in reality, a specific objective in juxtaposing those pursuits due to the significance of mutual interplay and interdisciplinarity so vital in corrosion reviews. it's was hoping that the corrosion scientists during this approach could remain abreast of the actions in corrosion expertise and vice versa. during this sequence the time period "corrosion" is utilized in its very broadest experience. It contains, as a result, not just the degradation of metals in aqueous en­ vironment but additionally what's in general known as "high-temperature oxidation. " extra, the plan is to be much more common than those themes; the sequence will comprise all solids and all environments. this day, engineering solids comprise not just metals yet glasses, ionic solids, polymeric solids, and composites of those. Environments of curiosity needs to be prolonged to liquid metals, a wide selection of gases, nonaqueous electrolytes, and different non­ aqueous liquids.

New Theories of Everything: The Quest For Ultimate Explanation

Can we ever find a unmarried clinical thought that tells us every thing that has occurred, and every thing that may ensue, on each point within the Universe? the search for the idea of every thing - a unmarried key that unlocks the entire secrets and techniques of the Universe - is not any longer a pipe-dream, however the concentration of a few of our most fun examine concerning the constitution of the cosmos.

Passions and Tempers: A History of the Humours

Physicians in old Greece believed 4 humours flowed in the human body—blood, phlegm, black bile, and choler—determining a person's overall healthiness, temper, and personality. now not until eventually the 17th century could a extra complicated view of the anatomy start to emerge. yet by means of then humoural conception had already turn into deeply ingrained in Western language and thought—and endures to this present day in wonderful methods.

Science Education for Diversity: Theory and Practice

Reflecting the very most modern concept on range matters in technology schooling, together with new dialogic ways, this quantity explores the topic from various views and attracts on reports from world wide. The paintings discusses primary subject matters akin to how we conceptualize variety in addition to studying the ways that heterogeneous cultural constructs effect the educating and studying of technology in a number of contexts.

An external tensile stress increased the initial parabolic oxidation rate but had no apparent effect on the subsequent linear rate. It is our opinion that this result may Surface Oxide Films at Elevated Temperatures 35 be expected since during linear oxidation the growth and oxygen solution stresses are likely to be high enough to cause continual oxide breakdown and hence no difference would be observed in the linear rate. However, during parabolic growth the internal stresses in the oxide may not be sufficient to cause breakdown, but the combination of internal and external stresses may cause failure of the oxide which will accelerate the oxidation process.

Anionic Oxidation on Convex Surfaces Compressive stresses are generated isothermally at the metal-oxide interface, which may result in decohesion for thin oxides. For thicker oxides the outer oxide will be in tension and failure may be by tensile cracking. The superimposition of a cooling cycle will enhance decohesion, particularly if the specimen radius is small, but will slightly reduce the possibility of oxide tensile failure, by inducing an increased compressive stress in the oxide. Cationic Oxidation on Concave Surfaces Isothermally, the inner oxide will be in compression and the compressive stress will reduce across the thickness of the oxide and may go into tension at the metal-oxide interface.

Similar oxidation of strips of Ta and Nb at 800°C 98 resulted in flexure behavior which could again be related to the predicted change in oxygen concentration gradients. The bending method (Fig. 25) was used by Roy and Burgess 99 to determine the stresses present in zirconium and Zircaloy-2 resulting from oxidation at 500°C. The oxidation kinetics of the two materials are different. 38 P. Hancock and R. C. ( reservoir Fig. 25. Schematic diagram of apparatus used in the bending method (after Roy and Burgess 99 ).
