the effect of rolling direction to the tensile
Tensile tests are commonly used to provide information on the tensile properties of materials. However, limited tests have been done on the orientation angles of material for the same properties. Thus, the present paper discusses the effect of three
As the ratio of inside radius and the material thickness decreases, the tensile strain on the outer surface of the material increases. When the ratio . This is made worse when the bend line is parallel to the grain or rolling direction of the sheet metal.

Deformation anisotropy of samples from rolled sheet and extruded rod of AZ31 alloy was investigated in the present work. A strong basal plane texture is detected formed during rolling and extrusion, and both rolled and extruded samples exhibit similar mechanical behavior:tensile yield strength is the highest in the specimens parallel to the longitudinal direction, and decrease continuously as Effect of Specimen Geometry on Tensile Testing ResultsThe short answer is that it depends on the tensile property and the characteristics of the material being tested. For a given cross-sectional area and for any gauge length, different specimen geometries have no effect on the ultimate tensile strength and the yield strength of standard materials.

Tensile strength was obtained for the rolling direction when rolled at 110°C lower than at other rolling temperatures. It was likely that the molecular orientation was decreased by increasing the springback when rolled at high temperature.

When the tension direction is parallel to the rolling direction, the maximum yield. strength was obtained. The results can help predict the behavior of small-scale beryllium. copper products more accurately.
The direction of the strain band is ±45° and 90° to the tensile direction, and the distribution is symmetrical. On the contrary, no obvious interference effect was found on the side with impact holes, and the crack initiation was mainly due to the stress concentration around the holes. Mechanical Testing - Tensile Testing Part 2 - TWIA rolled steel plate will be found to have different properties in the longitudinal, transverse and through thickness directions. Material specifications such as BS EN 10028, Flat Products in Steel for Pressure Purposes, therefore, require the tensile test to be taken transverse to the rolling direction so that the steel is tested across the
A plates grains run parallel to the rolling direction. Keep in mind that the plates grain direction is a result of the mills rolling process, which stretches the metallurgical structure and inclusions of the material. And, as noted previously, the metals grains run parallel to the rolling direction. The Fabricator points out that, Metal Rolling - ManufacturingIn any particular metal rolling process, it is important to understand how these deflections will affect the rolls and hence the work being rolled. The rolls initially start out flat. During a basic flat rolling operation, it can be observed that the work material will exert greater force on the rolls towards the center of the material than at
Sometimes in metal rolling practice, tension, (force), is applied to a work piece as it is being rolled. This tension may be applied to the front, (front tension), the back, (back tension), or both sides. This technique will assist the forces necessary to form the work, and is usually used on hard to roll materials. Rolling direction of an aluminium plateKnowledge of rolling direction does not have solely aesthetic benefits. During the machining of rolled aluminium, it is important to take the rolling direction into account. If, for example, aluminium bends the wrong way in relation to the rolling direction, there is a risk of breakage on the metal.
The rolling direction is important for the aesthetic appearance As you can see in the following images, the rolling direction creates structural lines on the aluminium surface. In order to create a uniform look, it is therefore important, for example, to place rolled plates with the rolling direction Rolling of Metals:Process and Principles (With Diagram)In rolling, the metal is plastically deformed by passing it between rollers rotating in opposite direction. The main objective of rolling is to decrease the thickness of the metal. Ordinarily, there is negligible increase in width, so that the decrease in thickness results in an increase in length.
the rolling direction and the transverse direction specimens are created, and the compressive-tensile tests are conducted on three conditions of strain rate 7.0x10-3, 10 and 100/s. As a result, it is shown clearly in Dual Phase steels that the dependence of strain rate on the Bauschinger effect exists. In addition, with the THE EFFECTS OF TEMPERATURE ON THE STRENGTH The PLC effect occurring at the conditions of the performed tensile tests, depends on the temperature and the direction of sampling with respect to the plate rolling direction. 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.

Recent observations that rolling direction surface striations are generated by tensile elongation transverse to the rolling direction have cast doubt on the validity of the plastic buckling model for roping in ferritic stainless steels. Moreover, these observations are seemingly incompatible with the transverse cross section undulations which characterize the roping morphology. The effect of rolling direction on the weld structure and It was found that there is a higher degree of softening of the heat-affected zone in the sample welded parallel to the rolling direction. Although this softening did not significantly decrease the tensile strength or the hardness of this sample when compared to the one welded transverse to the rolling direction, the elongation was twice as high in the former sample.
