Concerning Fracture and the role of microstructure book propagation the grain size is to be compared with the plastic zone size. When it is small, near Fracture and the role of microstructure book threshold, the grain size modifies the slip amplitude and it plays an important role on the threshold level.

In particular it determines the fracture surface roughness and this induces a smaller or larger crack by: 4. However, the role of microstructure should be accounted for. The dilemma caused by effects of the microstructure on both the resistance and the driving force for cleavage fracture is solved by seeking the factor combining both effects to strike a balance, such as the critical stress intensification factor Q c = σ f /σ.

Effects of the welding process variations on toughness are best understood by studying the weldment microstructure and the inclusion size distribution. We showed that the oscillatory pressure-driven densification played a significant role in the microstructure evolution of grains and the grain boundaries, and then enhanced the mechanical performances of by: 3.

The role of microstructure in affecting fracture toughness is examined by considering how microstructure affects the formation of a critical increment of crack extension leading to catastrophic fracture. It is proposed that this critical increment of crack extension occurs by void formation ahead of the main crack and growth back to it.

Factors affecting void nucleation and void growth are Cited by: Fatigue and Fracture ASM International Individual alloy classes are examined in detail to assess the understanding of relationships between microstructure and fatigue resistance.

Microstructure is the very small scale structure of a material, defined as the structure of a prepared surface of material as revealed by an optical microscope above 25× magnification.

The microstructure of a material can strongly influence physical properties such as strength, toughness, ductility, hardness, corrosion resistance, high/low temperature behaviour or wear resistance.
