The alteration in behavior of this function at intermediate load level, like in the case of low hardness steel sliding against high hardness steel, is observed. The analysis by scanning electronic microscope before and after this alteration showed a change of wear mechanism from plastic displacement to embrittlement.380-386porEmbrittlementHardnessLoads (forces)Plastic deformationScanning electron microscopySteelTemperingDual phase steelPlastic displacementWear of materialsInfluencia da Carga no Comportamento quanto ao Desgaste de um Aco ABNT-1020 Bifasico Revenido a 450°CInfluence of load on wear behavior of a dual-phase steel tempered at 450°CArtigoAcesso aberto2-s2.0-00295470862-s2.0-0029547086.pdf
