20.500.12556/DKUM-87765 Experimental study of crack propagation through cladded 316L/S355 steel produced by the hot-roll bonding process A hot-rolled clad plate made of 316L stainless steel and S355 carbon steel was produced in a real industrial environment via GMAW welding, vacuuming, preheating to 1240 °C, and hot-roll bonding on four stand plate mills in nine passes with reduction rates between 20-6% per pass. The clad plates were solution annealed to achieve the usual delivery condition. Ultrasound testing showed a bonding rate of 100%. Metallographic examination revealed predominantly low concentrations of oxides at the interface. The tensile strength of the bond reached 155 MPa. The shear strength always satisfied the requirements of ASTM A264. It was observed that the concentration of oxide particles influenced the shear strength strongly. The lowest measured value was 172 MPa. Specimens notched in the base material and specimens notched in the clad layer were used in the Charpy impact test. In every case, only the notched layer broke, while the other layer was only bent. The absorbed energies were always higher than those of each material alone. Fracture mechanic tests gave similar results. The crack could not propagate from the notched layer into the other one, regardless of the material of the notched layer. Instead, delamination occurred. Due to delamination, K1c could not be determined, so KQ was given instead. clad plate hot-roll bonding shear strength tensile strength impact toughness crack propagation bimetalne plošče spajanje z vročim valjanjem strižna trdnost natezna trdnost udarna žilavost širjenje razpoke titan true false true MDPI Angleški jezik Slovenski jezik https://www.mdpi.com/journal/metals Članek v reviji 2024-03-28 11:37:49 2024-03-28 11:54:24 2024-04-05 13:40:12 0000-00-00 00:00:00 2023 0 0 Str. 1-18 Št. 7, št. članka 1273 Letn. 13 July 2023 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2023-06-09 2023-06-22 2023-07-15 621.833.1:539.4 161158403 10.3390/met13071273 2075-4701 Bjelajac-2023-Experimental_Study_of_Crack_Prop.pdf Bjelajac-2023-Experimental_Study_of_Crack_Prop.pdf 1 549AF25DA1903001294E55FF4BDB616D ef9a96a4fbed6e00696f38f97d8157ab33761a9c0acedb702c11e416cdb5ac82 63e7bbb4-ecf1-11ee-9311-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=177509 https://doi.org/10.3390/met13071273 0 71a29983-ecf1-11ee-9311-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=177510 Fakulteta za strojništvo 0 0 0
