Original scientific paper In this paper, influence of flame spraying and fusing on microstructure of substrates made from heat treated carbon steel C45, a heat treated low alloyed 42CrMo4 steel and stainless austenitic steel X6CrNiMo18-10-2, has been investigated. Flame spraying and fusing is a deposition technique commonly applied to nickel-base self-fluxing alloys (NiCrBSi alloys). Because of...

in this study, the changes in microstructure of hp-nb cast heat resistant steel after 8 years of service at high temperatures were investigated. study of microstructure using optical microscopy (om) and scanning electron microscopy (sem) equipped with an energy dispersive spectrometry (eds) showed that the microstructure of this steel in as-cast condition includes an austenitic matrix, and that...

For analysing dynamically loaded structures by means of the finite element method a dynamic constitutive material model is necessary to obtain reliable results. For this purpose dynamic tensile tests were performed with the fine grained steel 20MnMoNi 5 5 (A508 CI. 3) and the austenitic steel X6CrNi 18 11'at different velocities. Smooth round bar specimens of different geometries were used. Dis...

Electron BackScatter Diffraction (EBSD) in conjunction with Field-Emission Environmental Scanning Electron Microscopy (FEG-ESEM) has been used to evaluate the microstructural and local plastic strain evolution in different alloys (AISI 1005, AISI 304L and Duplex 2205) deformed by a single-stage cold and warm forging process. The present work is aimed to describe the different behavior of the au...

Simulation results from using the cellular automata as an example of defects on the surface of austenitic stainless steel 08Cr18Ni10Ti are presented in this paper. Practically confirmed the feasibility of the proposed method for simulation modeling of corrosive process of steel in neutral environments.

Deuterium thermal desorption spectra were investigated on the samples of austenitic stainless steel 18Cr10NiTi preimplanted at 100 K with deuterium ions in the dose range from 3 × 10(15) to 5 × 10(18) D/cm(2). The kinetics of structural transformation development in the implantation steel layer was traced from deuterium thermodesorption spectra as a function of implanted deuterium concentration...
