AbhstractMechanical properties, microstructure and fracture pattern of bainite nodular cast-iron after austempering are studied in the range of temperatures 260-420 °C. Nonharmonic character of function of mechanical properties change in various temperature intervals of isothermal soaking is determined. Dependence of nonharmonic behavior of function of mechanical properties on structural condition is shown. Interrelation between fracture pattern of bainite nodular cast-iron and its metallic matrix type is illustrated fractographically. © Metallurgical and Mining Industry, 2010. Source

The article analyzes the spheres of 3D printing and 3D scanning modern technologies application, defines the perspectives of 3D technologies development, and proves the expediency of these technologies application in educational activities of a modern institution of higher education. The authors developed the training course curriculum that allows the students not only to acquire the knowledge and practical skills in the field of 3D printing (scanning), but also to get acquainted with the basics of entrepreneurship and principles of 3D technologies transfer. The article gives the matrix that describes in detail the competences, acquired by the students after getting acquainted with the course materials, developed by the authors. © 2016 by the paper authors.
