Title: Development of the choice procedure for separation method of section iron using complex criteria of materials destruction
Authors: Karnaukh, S.G.
Abstract: Cluster analysis of materials destruction criteria was performed. Yield point is considered to be the most informative criterion among traditional ones. “Scale” is considered to be the most informative criterion among complex ones. Besides, complex criteria such as crack proliferation criterion and brittleness criterion are the basic informative indicators. When adding any other complex criterion (nucleation or “scale”) they form the most informative sets of minimal power, providing materials classification according to their separation sensitivity with a given reliability. Taking into account the data received, recommendations for choice of separation method of section iron were developed. Value of maximum rolling plasticity, which was defined using a special method, represents an indicator, suitable for ranging rolling material according to the separation capacity2017-01-01T00:00:00ZResearch of the influence of deformation speed on energy and power adjectives of the process of three-point cold bend breaking and on alignment integrity of raw parts

Title: Research of the influence of deformation speed on energy and power adjectives of the process of three-point cold bend breaking and on alignment integrity of raw parts
Authors: Karnaukh, S.G.; Karnaukh, D.S.
Abstract: Data on the amount of general energy of deformation and destruction, and also on its constituents, duration of different phases of destruction, speed of the main shock-induced cracking for materials with different mechanical properties in three-point cold bend breaking with the use of multichan-nel system of high-speed registration of loading is obtained. On the basis of the analysis of ex-perimental data conclusions are drawn about the influence of loading speed on energy and power adjectives of partitioning and about alignment integrity of raw parts of different steel grades.2011-01-01T00:00:00Z
