K. Nowacki, Silesian University of Technology, Department of Metallurgy, Katowice, Poland One of significant factors affecting properties of steel is uniform distribution of non-metallic inclusions and alloy elements across the steel product cross-section. Acoustic treatment may be the final technological stage enabling the quality of steel to be influenced. Further research to be undertaken in...

M. Mihaliková, M. Német, Faculty of Metallurgy, Technical University of Košice, Slovakia The present paper deals with measurements of the increments of strain and hardness HV10 on automotive steel sheets. The car body manufacture trends are focused, in particular, on high energy absorption capability. In the manufacture of a car body, there are requirements for high plasticity and homogeneity o...

Inspired by a problem in steel metallurgy, we prove the existence, regularity, uniqueness, and continuous data dependence of solutions to a coupled parabolic system in a smooth bounded 3D domain, with nonlinear and nonhomogeneous boundary conditions. The nonlinear coupling takes place in the diffusion coefficient. The proofs are based on anisotropic estimates in tangential and normal directions...

C. Roman, “Stefan cel Mare” University, Faculty of Economics, Suceava, Romania. Iron and steel industry is an important sector of the real Romanian economy, knowing the fact that, generally, the metallurgy is a very important indicator of internal consumption. The most important companies in this sector are part of international groups (Arcelor Mittal, Mechel, TMK and Tenaris), which ensure an ...

Great efforts have been recently made in the world of metallurgy in order to reduce raw material consumption and particularly energy consumption. Although most metallurgical products are produced by the proved procedures of plastic forming, some changes appear owing to the following requirements: – improvement of product quality, – reduction of production costs, – increase of productivity as we...
