Crack arrest in Q+T steels has been caused by large energy required for the fracturing of carbides. Since carbides have large Young鈥檚 modulus, the energy spent for their fracture is very large. This ...
The observation of second-phase particles such as strengthening precipitates and nonmetallic inclusions on the fracture surface of steel specimens clearly indicates their importance in the overall ...
This article describes how NDT, FTE, FTP are used in engineering design through the fracture analysis diagram (FAD) ...
Three basic factors contribute to a brittle-cleavage type of fracture. They are 1. a triaxial state of stress ...
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 ...
Fracture mechanics approaches require that an initial crack size be known or assumed. For components with imperfections or defects (such as welding porosities, inclusions and casting defects, etc.) an initial crack size ...
Most alloys contain second phases which lose cohesion with the matrix or fracture and the voids so formed grow as dislocations flow into them. Coalescence of the voids forms a continuous fracture surface followed ...
