High strength aluminum bronze bushing the pre-tension deformation research

Because of the new high-strength aluminum bronze sets have good mechanical properties, high tensile strength, and good plasticity, high temperature resistance and easy machining, in the aerospace field and civil engineering have been applied, the alloy is Casting and deformation of dual-use alloy, the application prospect is broader. How to improve the performance of the new high-strength aluminum bronze sets more effectively is a common concern, pre-tension deformation, the pre-deformation of the high-strength aluminum bronze sets of microstructure and mechanical properties of the impact, And to obtain the best pre-deformation process to improve the performance of copper sets.

After the solution treatment, the pre-deformation tensile test is carried out. After the aging, the strength of the aluminum bronze sleeve is increased, which is an effective means of strengthening, but the plasticity will decrease. 5% pre-deformation to promote the aluminum bronze sets in the matrix of more strengthening phase (θ '' and θ ', etc.) diffuse precipitation, evenly distributed, so that the strength increases, while the plastic to get the best fit. For the requirements of high strength, and no plastic requirements of the workpiece, can be pre-deformation of 9% to 10%, so that the strength of 480MPa or more. Therefore, the study shows that high-strength aluminum bronze sets in mechanical engineering and most of the other operations have good application performance, is a new type of development of a more powerful, more cost-effective products.
