tensile strength‚ Aluminium is easily to bend and Copper has the average all capable of these three. It has been shown that‚ Three materials before cold rolling exhibits excellent bend properties so that‚ it is capable of being bent cold around a pin under high angle without crack or fracture‚ due to ductile behavior. Also it can be seen that surface quality of starting materials is better than of cold rolled samples. To sum up‚ As Cold rolling is a metalworking process it increases the strength and

pressure: where σ is stress (in Newtons per square metre or‚ equivalently‚ Pascals). F is force (in Newtons‚ commonly abbreviated N)‚ and A is the cross sectional area of the sample. Tensile Strength; The (ultimate) tensile strength is the level of stress at which a material will fracture. Tensile strength is also known as fracture stress. If a material fractures by ’crack propagation’ (i.e.‚ it shatters)‚ the material is brittle. Yield Stress; On a stress strain graph

Introduction Tensile test is also known as tension test. It is material’s strength test where pulling force is applied from two ends. It is very important mechanical property evaluation test which provides fundamental properties like strength‚ stiffness‚ elastic limit‚ ultimate tensile strength etc. in this test‚ test object are standard size and shape but different material‚ then direct comparison of properties of those materials can be made. We had used standard “dumb-bell” shaped

The heating pressure of 30‚ 40‚ 50 MPa‚ heating time of 3‚ 4‚ 5 sec‚ upset pressure of 60‚ 70‚ 80 MPa‚ upset time of 2‚ 3‚ 4 sec were used to weld the joints. L9 orthogonal design concept was used. Results revealed that no intermetallic phases were formed. By increasing the heat input the tensile strength of the joint
