The tensile yield strength of quenched and tempered low-carbon (< 0.10%) lath martensite with 5% nickel is analysed with respect to grain size and substructural parameters and at the same time effects from an addition of 0.3% molybdenum are investigated. Microstructures are studied in detail by ...

second phase particles, are selected as representative materials, respectively. The special effort aims to build a quantitative relation between yield strength and grain structure with a bimodal size distribution, which provides valuable insights to design and produce high-strength bimodal-grained Mg ...
The reason for the increase of the microstresses is the differences in the yield strength and strain hardening of the respective phases. Cyclic loading affects both macroscopic [10] and microscopic [6], [11] residual stresses. It is well known that the presence of residual stresses may ...
With a material having a high crack growth resistance, and provided yield is contained, the ja:math and ja:math resistance behaviours are essentially the same, for both bend and tensile loading. However, when the deformation is extensive, there can be a significant difference between the ja:...
and immediate failure after ultimate strength. It is challenging to correlate F–D curves and T–S relations directly as the measurements of F–D curves (macroscale) and T–S relations (microscale) are at different length scales29and there is a curve to curve relation between them. However, ...
Connections between crack initiation, growth, arrest, and overload fracture are established via these failure diagrams. Application of these diagrams for engineering components in service is outlined for diagnostic and prognostic purposes. Keywords: Griffith’s analysis; Kitagawa-Takahashi diagram; ...

With this work we have obtained models that relate the load on the yield strength, tensile strength, yield strength and maximum tensile with the corrosion degree on steel bars B500SD attacked by chlorides.E. MorenoA.CoboM. F. Canovas
