Strengthening Mechanisms in Fatigue

1970
The present state of knowledge of the role of metallurgical structure in the achievement of high fatigue resistance is critically examined and the application of such knowledge is discussed. At the present time resistance to fatigue is best characterized in terms of phenomenological parameters such as the cyclic strain hardening exponent. The effect of

Strength and Strengthening Mechanisms

1984
The strength of a material depends on various intrinsic and extrinsic factors. Although the most important is the chemical composition, the properties can be manipulated by altering the structure. Various mechanical, thermal, and surface treatments are used to create the desired balance of strength, hardness, and ductility.

Strengthening mechanisms in nanostructured aluminum

Materials Science and Engineering: A, 2008
Structural parameters that characterize deformation produced nanostructures are the structural morphology, boundary spacing, boundary misorientation and interior dislocation density. These parameters have been determined and related to the yield stress of nanostructured Al produced by accumulative roll bonding (ARB) based on mechanisms such as ...

Creep Strengthening Mechanisms

1982
In the choise of the materials for the most crytical high temening mechanisms in superalloys. Solid solution-, particle-, and dislocation-strengthening are considered in dislocation creep. σ∘ concept is discussed and σ∘ data of superalloys reported. Diffusional creep and grain boundary sliding are also examined.

THE STRENGTHENING MECHANISM OF FERROUS MARTENSITE

1963
Abstract : A model is proposed to account for the observed strengthening behavior of ferrous martensites. The model is based upon the inheritance of carbon rich regions by the martensite which were present in the austenite prior to transformation. These carbon rich regions strengthen the martensite in a manner analogous to the strengthening effect due ...

Dynamic Recovery as a Strengthening Mechanism

Solid State Phenomena
Recovery usually softens strain hardened coarse grained metallic materials but it can increase the strength of ultrafine grained materials. The present work shows evidence that dynamic recovery can produce strain-hardening behavior in ultrafine grained aluminum processed by high pressure torsion.

Strengthening Mechanisms in Nanostructured Materials

2022
Understanding the behavior of materials with nanoscale features is important because of both the size of engineering devices and the internal microstructure of more bulk materials. Many electronic components have been miniaturized in recent years to attend the high demand of technology development. Similarly, new stronger bulk metallic materials use nm-

Strengthening mechanisms in aluminum alloys

2011
The substructure of pure aluminum and over-aged Al-4Cu has been varied by mechanical and thermal treatments. The nature of this substructure and its resistance to annealing has been studied, together with the effect of the substructure on tensile strength at ambient and elevated temperatures.
