Introduction: CrWMnsteelisanalloysteelcomposedofchromium(Cr), tungsten(W),andmanganese(Mn).Itiscommonlyusedin industriesduetoitsexcellentcorrosionresistance,high temperatureresistance,wearresistance,andhighstrength. However,thebrittlenessofCrWMnsteellimitsitsapplicationin criticalsituationswherehighstrengthandtoughnessareboth required.Therefore,extensiveresearchhasbeencarriedoutto enhancethestrengthandtoughnessofthissteel. 1.Alloying: Theadditionofalloyingelementsplaysacrucialrolein improvingthemechanicalpropertiesofCrWMnsteel.Various elementssuchasnickel(Ni),molybdenum(Mo),andvanadium(V) havebeenconsideredtoenhancestrengthandtoughness.Nickel improvesthetoughnessandductilityofthesteelbystabilizingthe microstructure.Molybdenumcontributestotheformationoffine carbides,whichincreasesthestrengthandhardness.Vanadium providesgrainrefinement,whichimprovesbothstrengthand toughness.Throughcarefulselectionandoptimizationofalloying elements,CrWMnsteelcanachieveabalancebetweenstrength andtoughness. 2.HeatTreatmentTechniques:
