Significant variables, which determine ductility of steels, are to be found in the steel-making process, where the nature and distribution of inclusions is partly determined, and in subsequent solidification ...

There are several forms of embrittlement in steel like intergranular embrittlement, temper embrittlement, embrittlement caused by overheating and burning ...

Most groups of alloys can exhibit failure by cracking in circumstances where the apparent applied stress is well below that at which failure would normally be expected. Steels are no exception to this ...

Temper embrittlement is inherent in many steels and can be characterized by reduced impact toughness. The state of temper embrittlement has practically no effect on other mechanical properties ...

According to available information on the fracture toughness of high-strength alloys at low temperatures, the effect of low temperatures on toughness is generally dependent on the alloy base ...

In steels containing large-volume fractions of pearlite, deformation in the pearlite can initiate microcleavage crack formation at low temperatures and/or high strain rates. Since the fracture path is ...

There are thousands of steels available today, each one characterized by a particular trade name or alloy composition. Although a quantitative value of fracture toughness parameters (e.g., NDT ...

Fracture can be viewed on many levels, depending on the size of the fractured region that is of interest. At the macroscopic level fracture occurs over dimensions that are of the order of the size of ...

The fatigue properties of metals are quite structure-sensitive. However, at the present time there are only a limited number of ways in which the fatigue properties can be improved by metallurgical means ...

Materials develop plastic strains as the yield stress is exceeded in the region near the crack tip. The amount of plastic deformation is restricted by the surrounding material, which remains elastic. The size of this plastic zone ...
