摘要
为优化5083铝合金挤压型材的生产工艺,对拉伸变形及退火处理后的5083铝合金型材的力学性能及腐蚀性能进行了研究。结果表明,拉伸强化可以有效提升试样强度;完全退火降低了试样强度,提高了试样韧性;低温退火降低试样强度的同时还大幅降低了试样的抗腐蚀性能。考虑到成本因素优先考虑挤压+拉伸强化工艺流程,对于某些需要特定成型的船舶构件,也可考虑采用挤压+完全退火+拉伸强化的工艺流程。
In order to optimize the production process of 5083 aluminum alloy extruded profiles,this paper analysis the mechanical properties and corrosion properties of 5083 aluminum alloy profiles after tensile deformation and annealing treatment.The results show that the tensile strengthening can effectively improve the strength of the sample,complete annealing can reduce the strength of the samples and improves the toughness of the samples,low temperature annealing can reduce the strength of the samples,but also greatly reduce the corrosion resistance of the samples.Considering the cost factor,extrusion+stretch strengthening process should be given priority.For some ship components that need specific molding,extrusion+complete annealing+tensile strengthening processe may also be considered.
