For the specimens prepared with the same roll pattern, an increase in reduction ratio can bring an increment in illuminance uniformity and hardness of rolled samples. Index Terms— GO 3% Si-Fe, internal stress, mechanical Barkhausen effect. That causes higher thermal conductivity along the rolling direction and consequently higher amount of heat removal rate along the rolling direction than the transverse direction. Cogent Engineering: Vol. The experiments identified the behavior of the mechanical properties, microstructures and micro-hardness of the AISI4140 material at two forming speeds (rpm) and three passes in the thread rolling process. The results of this study indicate that the nanocrystalline grains grow up after rolling to a thickness reduction of 30%, 50%, and 70% at 700°C, the submicron crystalline grains were broken down and dispersed better in the matrix of the steel, rolled steel greatly increased its mechanical properties, as the deformation increased from 30% to 50%, the tensile strength increased from 650 to 1110 MPa, the … It was found that the equiaxed grains are severely elongated along the rolling direction with increased rolling reduction. This asymmetry means that residual stress of tensile type acts in rolling direction. (2018). Topic et al. The effect occurs even at such low temperature as 25°C, and is most in- tense in the temperature range 50-75°C, and then it gradually decreases as the temperature rises. Keywords: AA 5052; cold rolling; annealing; microstructure; … Introduction The. The impacts of rolling temperature on phase transformations and mechanical properties were investigated for AISI 316LN austenitic stainless steel subjected to rolling at cryogenic and room temperatures. 4%. Sheets of 2195 aluminum-lithium alloy were solution-treated at 507 °C for 30 min. The results showed that ultimate strength increased as sample thickness decr … with respect to the rolling direction were weaker because the density of the T 1 precipitates was lower and were insufficient to influence the deformation behavior. The effect of rolling direction on the weld structure and mechanical properties of DP 1000 steel. A literature review was performed to assess the effects of inclusions in carbon and alloy steels on their mechanical properties. Thus, significantly sensible outcomes as a function of processing parameters were obtained considering the thread strength viewpoints. The orientation of the sheet in relation to the rolling direction can be important in the bending operation. Abstract The microstructures and mechanical properties of homogenized-rolled AA5052 aluminum alloys with different rolling reductions and following annealing treatments were investigated by optical microscope, scanning electron microscope, X-ray diffractometer, micro-hardness and tensile tests. Free Online Library: Effect of Reduction in Thickness and Rolling Conditions on Mechanical Properties and Microstructure of Rolled Mg-8Al-1Zn-1Ca Alloy. Among the methods of reducing the anisotropy of tensile properties was stretching or cold rolling in different directions, (Ref 17). 1, 1491019. A cast Mg-8Al-1Zn-1Ca magnesium alloy was multipass hot rolled at different sample and roll temperatures. the effect of hot-working conditions on the mechani-cal properties of cold-rolled and annealed steel sheets were investigated. 5, No. One set was stretched to 3-5% in the 0°, 45°, and 90° angle with respect to the original rolling direction. I. Abstract Since gas metal arc welding (GMAW) is a common procedure to join different sheets in the industry, the welding direction dependence on the rolling direction was investigated for a welded DP1000, a cold-rolled dual phase steel. Mechanical properties, microstructure and texture evolution of these specimens were investigated after rolling. The effect of cold rolling, performed after friction stir welding (FSW), on the mechanical properties and formability of joints in AA5754-H114 aluminium alloy was investigated. Effects of cold rolling (CR) and annealing time on microstructure and mechanical properties of AA 5052 aluminum alloy. The effect of the rolling conditions and reduction in thickness on the microstructure and mechanical properties was investigated. hardness and tensile tests. Many attempts to minimize the mechanical anisotropy Ha and Park [9] studied the effect of the rolling direction on the development of the microstructure, texture, and mechanical properties of AZ31B alloys. mechanical properties of high toughness of titanium alloy under the effect of rolling process. Deformed grains have lower density of grain boundaries in the rolling direction than in the transverse direction. The effect of rolling direction on the weld structure and mechanical properties of DP 1000 steel. Tensile testing was used to determine the mechanical properties and anisotropic behavior of each condition. Rolling 6% reduction in thickness in the 45A degrees orientation yielded anisotropy of 7.6% in the yield strength. The results show that with increasing rolling reduction, the equiaxed grains are elongated along the rolling … Controlling Mechanism of Ferrite Grain Size Generated through Large Strain Deformation of 0.15C Steel p.687. Additionally, it is common to see mechanical property listed by the directional grain structure of the material. The effects of final rolling temperature on the microstructures, texture and mechanical properties of AZ31 Mg alloy sheets prepared by equal channel angular rolling and continuous bending (ECAR-CB) were investigated. The major findings are summarized as follows: (1) The microstructure of rolled sheets consists of fibrous structure with elongated grains, and shear bands along the rolling direction after warm rolled. The effects of hot rolling on the microstructure and mechanical properties of as‐cast Al‐15Mg 2 Si, Al‐20Mg 2 Si, and modified Al‐15Mg 2 Si in situ composites are studied. Mechanical properties are generally specific to product form such as sheet, plate, extrusion, casting, forging, and etc. If, for example, aluminium bends the wrong way in relation to the rolling direction, there is a risk of breakage on the metal. Related content Through-process modelling of texture and anisotropy in AA5182 When subjected to a bending test, these elongated defects lower the resistance to fracture. 1.

I. Schindler, M. Mistecky, M. Ruzicka, L. Cizek, [8] interested with the Effect of cold rolling and annealing on mechanical properties (tension, hardness and micro structure) of HSLA Steel alloy. Also, the change of rolling direction affected both the yield strength and the Young’s modulus. A pronounced size effect was observed at a thickness of 76 μm. Kusmono; Department of Mechanical and Industrial Engineering, Faculty of Engineering, Universitas Gadjah Mada, Jl. When the tension direction is parallel to the rolling direction, the maximum yield strength was obtained. To study the size effect on the properties of copper, tensile tests were performed with pure copper foil (thickness range from 25 μm to 300 μm) by cold rolling. Knowledge of rolling direction does not have solely aesthetic benefits.
