    Statistical aspects of fatigue data, the planning and evaluation of fatigue tests, and the characterization of fatigue mechanisms and crack growth are also covered. Practical applications and examples of fracture control in weldments, process piping, aircraft systems, and high-temperature crack growth and thermos-mechanical fatigue are also. These proceedings entitled, FATIGUE - ENVIRONMENT AND TEMPER\u00AD ATURE EFFECT, address the overview of temperature and environmental effects of fatigue, room temperature environmental effects, high temperature and environmental effect - mechanisms, high tempera\u00AD ture and environmental effect - mechanisms, materials and design-engineering.

    Contains more than fatigue curves for industrial ferrous and nonferrous alloys. Also includes a thorough explanation of fatigue testing and interpretation of test results. Each curve is presented independently and includes an explanation of its particular importance. The curves are titled by standard industrial designations (AISI, CDA, AA, etc.) of the metals, and a complete reference is 5/5(3). The effects of corrosive environments on the fatigue behavior of metals were studied as early as The phenomenon should not be confused with stress corrosion cracking, where corrosion (such as pitting) leads to the development of brittle cracks, growth and failure.

The Effect of Environment and Temperature on the Fatigue Behavior of Titanium Alloys J. Ruppen, C. Hoffmann, V. Radhakrishnan, A. McEvily Pages Environmental effects on fatigue behavior of metals book Since metal alloys are still today the most used materials in designing the majority of components and structures able to carry the highest service loads, the study of the different aspects of metals fatigue attracts permanent attention of scientists, engineers and designers.

Fatigue of Materials covers a broad spectrum of topics that represent the truly diverse nature of the subject that has grown to become a key area of scientific and applied research. Constituting an international forum for the materials industry, the book provides the perspectives of operators, engineers, and researchers regarding all aspects of current and emerging technologies for materials.

7 Environmental Effects on Fatigue Testing Fatigue behavior of most engineering materials is adversely affected in the presence of any corrosive environment, such as moist air or aqueous solutions, saline or gaseous environment under ambient and elevated temperature conditions.

The effects of grain size, spanning the nano- to the micro-crystalline regimes, on the fatigue behavior of metals were investigated. Grain refinement in the nc and ufc regimes has been shown to have a substantial effect on stress-controlled fatigue life, as well as the fatigue crack growth by: In addition to cyclic stress, it has been well documented that the mean stress plays an important role in the fatigue of metals.

In order to include the effects of both cyclic stress and mean stress, it is a common practice to combine these two types of stress into a single parameter of ‘effective fatigue stress’ to correlate with fatigue life.

ENVIRONMENTAL EFFECTS ON FATIGUE BEHAVIOR OF METALS INTRODUCTION The role of environment in fatigue behavior has received a great deal of attention in the past decade.

While it has been known for a great many years that the environment can significantly affect fatigue properties, only in recent years hasCited by: 1. Significant influences of environment on fatigue behavior of metals have been found in many metal/environment systems.

The fatigue crack growth rate can be higher in a corrosive environment than in an inert environment, such as vacuum, and it depends on the chemical and electrochemical variables in the by: The effects of microstructure and axial tension on the fatigue behavior of TC4 titanium alloy in high cycle (HCF) and very high cycle (VHCF) regimes are discussed in this paper.

Effect of Surface Integrity on Fatigue of Structural Alloys. The effects of environmental media on the corrosion fatigue fracture behavior of 25CrMo steel were investigated. The media include air, and wt % and wt % NaCl solutions.

Experimental results indicate that the media induces the initiation of corrosion fatigue cracks at multiple sites. Nanocrystalline metals have been shown to exhibit unique mechanical behavior, including break-down in Hall-Petch behavior, suppression of dislocation-mediated plasticity, induction of grain boundary sliding, and induction of mechanical grain coarsening.
