Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aluminum alloy wires lack sufficient high-strength properties after solution treatment and aging treatment, necessitating the development of a composition and manufacturing method that enhances tensile strength, heat resistance, and corrosion resistance.
Innovation Solution
An aluminum alloy wire with a specific composition of silicon (0.6-1.5 mass%), magnesium (0.5-1.3 mass%), copper (0.1-1.2 mass%), and manganese (0.2-1.15 mass%), along with optional elements like iron, chromium, zinc, titanium, and zirconium, is manufactured through a process involving cold drawing and softening treatments to achieve a high degree of orientation of the 111 plane, resulting in improved tensile strength and resistance properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional aluminum alloy compositions are used, then manufacturing is easier, but tensile strength after solution treatment and aging treatment is insufficient
Solution Approach 1:
The patent applies parameter changes by precisely controlling the composition ranges of alloying elements (Si: 0.6-1.5%, Mg: 0.5-1.3%, Cu: 0.1-1.2%, Mn: 0.2-1.15%) to achieve optimal tensile strength after solution treatment and aging treatment while maintaining manufacturability
Solution Approach 2:
The patent uses composite materials by creating a multi-element aluminum alloy system combining Si, Mg, Cu, and Mn in specific proportions to achieve superior mechanical properties that cannot be obtained with conventional single-element or binary alloys
2Strength
If cold drawing is performed to increase degree of orientation, then tensile strength improves, but manufacturing complexity increases
Solution Approach 1:
The patent applies preliminary action by performing cold drawing before solution treatment and aging treatment to establish the desired degree of orientation of the 111 plane in advance, so that the microstructure is pre-positioned to achieve high tensile strength after subsequent heat treatments
Solution Approach 2:
The patent segments the manufacturing process into distinct stages: cold drawing to create orientation, followed by solution treatment and aging treatment to develop strength, allowing each process to be optimized independently while achieving cumulative benefits
