TLDR
In this paper, an aluminum alloy automobile wheel hub composite reinforcement technology is presented, where trace elements are added on the basis of original alloy components to carry out a reasonable component optimization, and effective purification, crystal grain refinement, deterioration treatment and finished product heat treatment are carried out in the melting process to simultaneously guarantee the good casting performance and the better mechanical performances of the alloy.Abstract:
The invention discloses an aluminum alloy automobile wheel hub composite reinforcement technology. Trace elements (comprising Mg, Ti, B, RE and the like) are added on the basis of original alloy components to carry out a reasonable component optimization, and effective purification, crystal grain refinement, deterioration treatment and finished product heat treatment are carried out in the melting process to simultaneously guarantee the good casting performance and the better mechanical performances of the alloy. The tensile strength, the yield strength and the elongation rate of aluminum alloy wheel hub products produced through utilizing the technology reach 262MPa, 179MPa and 9% respectively, and exceed strength performance standards in the Chinese wheel hub industry, so the technology has the advantages of certain practical production meaning, heat treatment period shortening, and substantial saving of the production cost.read more
