Metallic Glass Inserts for Structural Interrelation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge lies in structurally interrelating components using inserts fabricated from metallic glass-based materials, as conventional methods often rely on heritage engineering materials like steel, aluminum, or titanium, which can be limited by galvanic corrosion concerns and lack the advantageous properties of metallic glass-based materials, such as higher elastic strain limits and corrosion resistance.
Innovation Solution
The use of metallic glass-based materials for inserts, which can be fabricated through thermoplastic forming or casting techniques, providing unique properties like high hardness and corrosion resistance, and can be designed with textured surfaces or extensions to enhance bonding, allowing for efficient structural interrelation of components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If heritage engineering materials (steel, aluminum, titanium) are used for inserts, then ease of manufacture and adjoinability are improved, but galvanic corrosion resistance and elastic strain limits deteriorate
Solution Approach 1:
The patent changes the material parameters by using metallic glass-based materials with specific compositions (e.g., Zr-Cu-Ni-Al, Ti-Zr-Cu-Be) that possess superior corrosion resistance and elastic strain limits compared to conventional materials, while maintaining manufacturability through casting and thermoplastic forming processes
Solution Approach 2:
The patent employs composite material strategies by creating inserts from metallic glass-based materials that combine multiple elements (e.g., Zr, Cu, Ni, Al, Ti, Be) to achieve a synergistic effect that provides both high corrosion resistance and high elastic strain limits, overcoming the limitations of single-element heritage materials
2Reliability
If metallic glass-based materials are used for inserts, then corrosion resistance and elastic strain limits are improved, but manufacturing complexity increases
Solution Approach 1:
The patent extracts the essential functional requirements (corrosion resistance and elastic strain limits) from the complex metallic glass material system and implements them through simplified manufacturing processes such as direct casting and thermoplastic forming, eliminating the need for complex multi-step manufacturing sequences
Solution Approach 2:
The metallic glass-based materials exhibit self-service characteristics through their inherent high corrosion resistance and elastic strain limits that are intrinsic to the material structure, eliminating the need for additional protective coatings or complex manufacturing interventions to achieve the desired performance
3Reliability
If metallic glass-based materials are used for inserts, then wear resistance and environmental resilience are improved, but ease of adjoinability deteriorates
Solution Approach 1:
The patent applies local quality by providing the metallic glass-based inserts with a textured outer surface that creates localized areas enhanced for bonding, while the bulk material maintains its superior wear resistance and elastic strain limits, thus achieving both adjoinability and durability
