Bending Fatigue Strength

The effect of laser welding on prevention of the fracture of cracked shafts of a high carbon steel are presented. Static tensile strength and rotary bending fatigue strength were obtained using shaft specimens of AISI W1 which were welded by a CO2 laser around a precrack. Since the welded region became extremely hard and brittle, both the strengths of laser-welded specimens were lower than those of non-welded specimens. However, the strengths were increased higher than those of non-welded specimens after tempering the specimens. It was found that when tempered at 600°C after laser welding, the rotary bending fatigue strength of specimens with a crack smaller than 12 mm rose similar to that of the base metal, and when tempered at 700° C, the static tensile strength of specimens with a crack smaller than 12mm rose similar to that of the base metal. Therefore, it was shown that the laser welding is very effective to prevent fracture of high carbon steels.

Optimal Value

In this work the influence of value of single draft on mechanical-technological properties of high carbon steel wires was evaluated. For wires drawn with medium single draft (10.4 %, 15.5 % and 26.5 %) the investigation of mechanical-technological properties was performed thereby providing results on yield strength, tensile strength, elongation, contraction, number of twist and number of band. On the basis of numerical analysis of wire drawing process the influence of the value of single draft on inhomogeneity of strain was determined. It was established that in the range of medium single drafts 10-26 % used in drawing process of high carbon steel wires large single drafts cause the increase of their strength properties by deterioration of their plasticity properties. It was demonstrated that the increase of strength properties in wires drawn with larger single drafts is related to the occurrence of higher non-dilatational strain, which cause additional work hardening of material. The theoretical-experimental analysis of drawing of high carbon steel wires enabled evaluation of optimal value of single drafts by which it can be used relatively the most advantageous useful properties of wires. Obtained research results can be applied while designing the production process of high carbon steel wires.

Drawing Speed

Abstract In this work the influence of the drawing speed on lubrication conditions and mechanical properties of high carbon steel wires drawn in conventional and hydrodynamic dies has been assessed. The drawing process of ϕ5.5 mm wires to the final wire of ϕ1.7 mm was conducted in 12 passes, in industrial conditions, by means of a modern Koch multi-die drawing machine. The drawing speeds in the last passes were: 5, 10, 15, 20 and 25 m/s. For final wires ϕ1.7 mm the investigation of mechanical properties has been carried out, in which yield strength, tensile strength, uniform and total elongation and also number of twists were determined. It has been shown that the increase of drawing speed from 5 m/s up to 25 m/s caused the increase by 6% strength properties and decrease of plasticity properties by 10%. Higher values of tensile strength and yield strength of the wires drawn conventionally with high speeds are associated with worse conditions, while in case of wires drawn hydrodynamically the main factor which caused the increase of strength properties was high lubricant pressure in hydrodynamic die, which caused the increase of total draft.

Proof Strength

A high carbon steel joint, S70C (0.72wt%C) was successfully friction stir welded without any postheat treatments. There are two methods for obtaining proper joint properties. The first method is to decrease the peak temperature to below A1, and the other method to decrease the cooling rate to less than the lower critical cooling rate. As a result, the ultimate tensile strength of 1214 MPa, 0.2 % proof strength of 700 MPa and elongation of 40% were obtained for a joint.

Drawing Method

High carbon steel wires, due to their high mechanical strength and high fatigue characteristics, have been widely used in industrial products such as bridge cables and steel cords for tires. To produce wires that match the requirements for those purposes, wire drawing process is used. However, after the processing, tensile strength of the wires increases, but ductility decreases due to the shear deformation near the wire surface. In this study, we examined ductility improvement methods of high carbon steel wires and as a solution we suggest a method of processing called “alternate wire drawing”. The next step was to determine the usefulness of alternate wire drawing for increasing the ductility of the wires. Firstly we studied the total equivalent strain and the change of the shape of elements for each drawn wire by FEM analysis before testing. It was determined that in the case of alternate drawn wire the deformation of the elements was small also alternate wire drawing method is inhibiting the increase of total equivalent strain on wire surface. In case of tensile testing of drawn wire, we examined the mechanical properties of each wire drawing method and compared them. By doing this test we understood that in the case of alternate drawing there is a significant increase of breaking strain and drawing rate. We also have done torsion test to confirm the ductility of conventional wire drawing and alternate wire drawing. In case of conventional wire drawing method (Total reduction 91.7%) delamination appeared, however alternate wire drawing method (Total reduction 91.7%) there was no delamination. In addition, in case of total reduction of 97.2%, alternate drawn wire increases 20% more its torsion characteristics, than conventional drawn wire. And we also studied the changes of the crystal grain of drawn wire by EBSD (Electron Back Scatter Diffraction Patterns). We found out that grain size was shrunk by conventional drawn wire due to share deformation and for alternate drawn wire we confirmed that it was possible to inhibit the grain shrinking by 15% compared to the conventional drawing method. As a conclusion we found out that, by using alternate wire drawing method it is possible to improve the ductility of high carbon steel wires with the high tensile strength.

Strength And Ductility

The effect of areal reduction for one pass on mechanical properties of high carbon steel wire drawn using wet-type non-slip drawing machine was investigated. The wires of 0.443 mm in diameter with carbon 0.98% were drawn to 0.06 mm in diameter by reducing the sectional area of the wire by 14 % and 27 %. Tensile strength increased monotonically with increasing drawing strain and there were very few differences of tensile strength by pass schedule. Elongation had the minimum value at 2.5 of drawing strain and reduction of area also had the maximum value at 1.2 of drawing strain. Elongation and reduction of area were improved in the region of drawing strain more than about 3 by decreasing areal reduction for one pass. Therefore, the wire can be drawn with maintaining strength and ductility under small areal reduction for one pass at latter pass regardless of areal reduction at former passes.
