Friction Pressure

In this study, Ti6Al4V rods were butt-welded by rotary friction welding. The experimental results show that the weld quality, in terms of the tensile strength and hardness, decreases radially. Therefore, the radius of the welded parts that are viable for rotating friction welding is limited because the areas located far from the centre of the axis have poor mechanical properties. The parameter that impacts the tensile strength and microhardness the most during rotary friction welding of Ti6Al4V is the axial pressure, which includes the friction pressure and forging pressure. A high forging pressure produces fine, equiaxed, and recrystallized grain structures in the welded joint, resulting in a high tensile strength and microhardness. In addition, an increased forging pressure can be used in rotary friction welding to reduce the radial differences in the mechanical properties of the welded joints.

EN24 steel is widely used in many engineering applications such as shaft, axle and fasteners due to high tensile strength and low cost. Friction welding is generally used to join the similar and dissimilar materials. The present work investigates on the mechanical properties of friction welded EN 24 steel joints. The effects of the four main parameters: friction duration, forging time, friction pressure and forging pressure on the mechanical properties of the weld such as hardness and axial shortening are studied experimentally and analyzed using ANOVA statistics.

Abstract Lucefin Group C30, C30E, and C30R are medium-carbon, non-alloy steels that are used in the normalized, cold worked, or quenched and tempered condition. C30E and C30R may also be flame or induction hardened. C30, C30E, and C30R are widely used for small, moderately stressed parts, where higher strength levels are needed than can be achieved in the lower carbon grades, and also where toughness is more important than high tensile strength. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on forming, heat treating, machining, and joining.
