Fractures of Structural Steels (Part 2)

Fractures of group II (according to the classification given in Part 1) are described in detail. The deviations of the structure of a fracture from the groups of fiber and crystalline fractures are explained by the chemical micro- and macroinhomogeneity of the metal. The characteristics of fractures, the causes of their formation, the methods for fighting and eliminating them, and the interrelation with the mechanical properties of the steel are described. Every kind of fracture is illustrated.

Fracture Surfaces of Structural Steels

The kinds of fracture of standard process samples and impact specimens obtained due to single static or impact bending are classified in accordance with the conditions and causes of their formation. Group I of fractures in this classification is considered, namely, fiber and crystalline fractures of structural steels, their characteristics, conditions and causes of formation, and interrelation with mechanical properties. Every kind of fracture is illustrated.

Fractures of Structural Steels (Part 4)

Group II of fractures (in accordance with the earlier suggested classification [1]) is considered. This group is represented by fractures caused by discontinuities existing in the metal. The fractures are described and causes of their formation determined. Methods for prevention and elimination of fractures of this kind and their relationship with the mechanical properties of the steel are presented. Every kind of fracture is illustrated. __________ Translated from Metallovedenie i Termicheskaya Obrabotka Metallov, No. 6, pp. 34 – 39, June, 2005.
