Item Investigation of the Element Diffusion in Friction Welded X53CrMnNiN219 and X45CrSi93 SteelsUzkut, M; Ünlü, BS; Yavuz, M; Akdag, MIn this study, high alloyed steel bars with a diameter of 12.30 mm made up of 1.4871 (X53CrMnNiN219) and 1.4718 (X45CrSi93) steels were used as experimental material for friction welding. Metallographic and X-ray diffraction investigations as well as microprobe sampling were performed on the samples. Mechanical orientation of particles caused by plastic deformation and carbide scattering has been observed. The diffusion behaviour has been investigated for the elements Cr, Ni, Mn, and Si, respectively. The existence of (Cr,Fe)(7)C-3 carbides in the welding region was also observed.Item Determination of optimum welding parameters in connecting high alloyed X53CrMnNiN219 and X45CrSi93 steels by friction weldingUzkut, M; Ünlü, BS; Akdag, MIn this study, different welding parameters were applied to two different steels with high alloys and mechanical and metallographical investigations are performed. Thus, the optimum welding parameters were determined for these materials and working conditions. 12.30 diameter steel bars made up of 1.4871 (X53CrMnNiN219) and 1.4718 (X45CrSi93) steel were used as experimental material. The material loss increased with increase in friction and rotating pressure. No fracture at the welding region was observed and the highest fracture energy was identified in B5 group. Based on micro hardness investigation; the hardness profile reached its minimum value at the welding region.Item Processing of tincal and colemanite ores by decrepitation method and comparison with wet method in terms of production costAkdag, M; Batar, T; Ipekoglu, U; Polat, M
