CHAPTER 4:IMPERFECTIONS IN SOLIDS Elastic behavior:This reversible behavior often shows a linear relation between stress and strain. To minimize deformation, select a material with a large elastic modulus (E or G). Plastic behavior:This permanent deformation behavior occurs when the tensile (or compressive) uniaxial stress reaches s y.
Chapter 6 - 3 Stress and Strain Stress:Pressure due to applied load. area force stress = = tension, compression, shear, torsion, and their combination. Strain:response of the material to stress (i.e. physical deformation such as elongation due to tension).
Corrosion Properties of 34CrMo4 Steel Modified by Shot A nanocrystalline layer was prepared on the surface of 34CrMo4 steel by time controlling shot peening (SP, i.e., 1, 5, 10, and 20 minutes). Field emission scanning electron microscopy (FESEM), X-ray diffraction (XRD) analysis, and transmission electron microscope (TEM) were applied to analyze the surface, cross-sections, and grain size of the specimens before and after SP.

Apr 01, 2010 · Conclusions The results of the fatigue investigations on quenched and tempered steel 42CrMoS4 with two different tensile strength (R m = 1100 MPa, 1350 MPa) and nodular cast iron EN-GJS-900-2 at R = -1 and R = 0 can be summarized as follows:Notched specimens (K t = 1.75) show a fatigue limit in the investigated lifetime region up to N = 2Ã
INVESTIGATION OF MICROSTRUCTURES AND 30 minutes-tempered samples. Figure 4 shows the tensile properties of as-quenched and 30 minutes-tempered sample of 440C martensitic stainless steel. It can be clearly seen that the UTS of the as-quenched sample was 517MPa and YS of 124Mpa. However, the UTS and YS of the as-tempered sample are 1044MPa and 368MPa, respectively.
Microstructure and Mechanical Properties of 34CrMo4 Steel From Figure 5, the 34CrMo4 base material exhibits good ductility compared with the test results of the product materials. Compared with the base material, the tensile properties of the CF and HD materials are obviously enhanced.
For comparison sake, it would be appropriate to mention here the properties of the quenched and tempered 34CrMo4 steel currently being used in industry. These are YS = 703 MPa, UTS = 814 MPa, hardness = 245 BHN and % elongation = 22 [ 13
