Abstract

The invention provides a method for improving the Fe content allowedness of a high-strong and high-toughness aluminum alloy for an automobile structural part. A cast aluminum alloy material which is easily recycled and has high-strength and high-toughness performance is obtained, by means of reasonable component design, by means of the method that adding of Ce+La mixed rare earth elements and adding of ultrasonic vibration are combined, a Fe-rich phase is refined, harm of the Fe phase to the mechanical performance is reduced, it is guaranteed that the aluminum alloy still has high strength andhigh toughness when the Fe content in the aluminum alloy is larger than 0.20% and smaller than or equal to 0.5%, the Fe content allowedness is improved, the high-strength and high-toughness cast aluminum alloy can meet the requirements of the large complex thin-wall structural part for the high-strength and high-toughness die-cast aluminum alloy material while keeping good die-cast formation performance, meanwhile, the aluminum alloy can be recycled, and the cost is reduced.

Description

technical field

[0001] The invention belongs to the technical field of aluminum alloys, and in particular relates to a method for increasing the Fe content tolerance of high-strength and tough aluminum alloys used in automobile structural parts. Background technique

[0002] Due to the need for lightweight automobiles and the development of new casting technologies, especially the vigorous development of electric vehicles in recent years, it has become an inevitable trend to replace some steel parts, aluminum forgings or multi-component combinations with cast aluminum alloy complex structural parts. Aluminum alloy structural parts are load-bearing parts, which put forward higher requirements for alloy materials. Unlike traditional die-casting alloys with low elongation, aluminum alloy materials for structural parts must have both high strength and high toughness, and take into account good formability. At present, aluminum alloy materials for structural parts are mostly de...
