20.500.12556/RUL-128362 Process parameters optimization for maximizing tensile strength in friction stir-welded carbon steel Optimizacija parametrov procesa za povečanje natezne trdnosti ogljikovega jekla, torno varjenega z gnetenjem The present study focuses on improving the ultimate tensile strength of friction stir welded carbon steel (AISI 1018). The effect of the process parameters (welding speed, tool RPM, and shoulder diameter) on the response parameters (ultimate tensile strength, percentage elongation and percentage reduction in area) were studied. Response surface methodology was used to develop the mathematical model for response parameters, and the adequacy of the model was checked using analysis of variance (ANOVA). The welding speed and tool RPM were found to affect the ultimate tensile strength significantly. The percentage elongation was affected only by welding speed. The percentage reduction in the area was affected by welding speed and shoulder diameter. The microstructure and microhardness of the weld have been studied and reported in the study. friction stir welding steel ANOVA response surface methodology ultimate tensile strength microstructure microhardness torno varjenje z gnetenjem jeklo ANOVA metoda odzivnih površin porušitvena natezna trdnost morfologija loma mikrostruktura mikrotrdota true false true Angleški jezik Slovenski jezik Članek v reviji 2021-07-09 13:39:48 2021-07-09 13:39:52 2025-03-11 14:57:35 0000-00-00 00:00:00 2021 0 0 Str. 311-321 no. 6 Vol. 67 June 2021 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 621.791 0039-2480 10.5545/sv-jme.2021.7203 69842435 RAZ_Bhatia_Anmol_2021.pdf RAZ_Bhatia_Anmol_2021.pdf 1 C8C951332DC2F087093234F5C8960093 d83feecf20a496aef0f9add67d3dd67b26269d4dae22dee044c833120a11be90 a502d667-e0aa-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=145079 https://www.sv-jme.eu/sl/article/process-parameter-optimization-for-maximizing-tensile-strength-in-friction-stir-welded-carbon-steel/ 1 3ff125b7-e0aa-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=145078 Fakulteta za strojništvo Strojniški vestnik 0 0 0
