Tensile and Fatigue behavior of shallow cryogenically treated En19 alloy steel 2019-28-0100

Wear, tensile and axial fatigue tests were conducted on shallow cryogenically treated En19 medium carbon alloy steel to investigate its mechanical behavior. The test samples are conventionally heat treated then oil quenched at 34 ˚C. Followed by the samples were kept under shallow cryogenic treatment to -80˚C for 12 hours using liquid nitrogen. Then the samples were tempered in a muffle furnace to relieve the induced residual stresses. Wear, Tensile and axial fatigue test was carried out on both treated and non-treated samples to measure its wear resistance, tensile strength and fatigue behavior respectively. Microscopic examination also done using scanning electron microscope to compare the effect of shallow cryogenic treatment on its microstructure. The results exposed that there is a reduction in the tensile strength and fatigue life of shallow cryogenically treated samples over base metal and improved wear resistance.
