Study of the Mechanical Properties by Using Thermo- Mechanical Processing of Alloy Steel


The purpose of this work is to study the effects of thermo mechanicaltreatments to improve mechanical properties of the alloy steel (DIN 42 Cr Mo4), suchas tensile strength, toughness, and hardness. All mechanical factors affected by themetallurgical changes in alloy like microstructure refinement and appearing newphases are thoroughly discussed.Heating was done in induction furnace at 1150oC and specimens were forgedin temperature of 1000oC but the forging process was done with different forgingloads (deformation percentage) with values of (800, 1000, 2500 and 4000 tons) with adeformation percentages of (26%, 31%, 45% and 61%) respectively.
