Non-metallic inclusions usually deteriorate mechanical properties and surface quality of steel products. Presence of non-metallic inclusions might have negative affected some of the mechanical properties of steels like ductility, toughness, anisotropy, and formability. Macroscopic method for assessing the content of non-metallic inclusions in forge...

In this paper, a pressure vessel test is described which is viewed as an axis-symmetric structure in order to perform an initial check of the adopted model defined by the plate-like finite elements. This approach gives the possibility of comparing the results obtained for the stress and deformation field with the patterns of classical elasticity th...

In conducted research was made a characterisation of microstructure and powder NiCrAlY, before and after applying on the base material. Coating was carried out by using HVOF Diamond Jet procedure, which uses the kinetic energy of the metal particles produced by on explosion of combustible gases. Characterisation was based on chemical analysis of me...

Carburizing is a very popular method of thermochemical treatment to increase the surface hardness of steel parts. It is achived by heating the steel at an austenite temperature in an environment of appropriate carbon source. Carbon sources provide the corresponding so-called a carbon potential (C potential). In the case of equilibrium state, the ca...

Basic raw materials for paper production are cellulose fibers and water. Water plays a major role in the process of cellulose and paper production and it is present in almost all phases of the cellulose fiber production process. Because of that the cellulose and paper industry is considered to be one of the largest consumers of natural resource pol...
