Experimental and Finite Element Investigation of Annealing on the Torsional Aspects of Carbon Steel St35

Th is investigation explain the effects of annealing on the torsion aspects of carbon steel St.35. ANSYS12 software was used in investigation. Test specimens were prepared according to ASTM and heated with different temperature namely 850, 650, 450 and 150 ° C for one hour and followed by cooling process via furnace. M icrostructure and torsion test after heating were examined. It was found that increasing annealing temperature, the hardness decreased and torsion properties and consequently increasing the plastic depth and the optimu m heat treatment conditions is annealing at 450° C which produce angle twist 680 deg co mpared with metal as received.
