Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge lies in efficiently recycling and reprocessing metal waste materials, particularly group four alloys and bulk metallic glasses, which are prone to contamination and composition deviations, leading to unsuitable feedstock for manufacturing due to their reactivity and sensitivity to impurities, resulting in significant losses and bottlenecks in supply chains.
Innovation Solution
A method involving the combination of a mongrel alloy, predominantly containing group four elements, with a correction alloy in optimized ratios to form a target alloy with desired properties, where the mongrel alloy exceeds or equals the mass of the correction alloy, and subsequent processing techniques such as melting and quenching to achieve a homogenous, amorphous structure with enhanced mechanical properties.

Engineering Contradiction Analysis
1Loss of substance
If metal waste materials are recycled and reprocessed, then sustainability and material utilization are improved, but contamination and composition deviations increase leading to unsuitable feedstock
Solution Approach 1:
A correction alloy is introduced as an intermediary substance to counteract the harmful effects of contaminants in recycled mongrel alloy. The correction alloy contains specific elements (Cu, Ni, Fe, Nb, Ta, V, Al, Be) that compensate for composition deviations and prevent formation of unwanted phases, thereby enabling the recycled material to meet manufacturing specifications without requiring complete reprocessing or virgin material substitution.
Solution Approach 2:
The invention modifies the chemical composition parameters of the recycled alloy by controlling the addition ratio of correction alloy (5-50 mass%). This parameter adjustment transforms the composition of contaminated mongrel alloy into a corrected alloy that achieves desired properties such as amorphous structure formation, improved glass-forming ability, and enhanced mechanical properties while maintaining sustainability benefits.
2Manufacturing precision
If strict material certifications and specifications are enforced, then product quality is improved, but manufacturing complexity and losses increase
Solution Approach 1:
The correction alloy serves as a mediating substance that simplifies the manufacturing process by automatically compensating for common contamination issues during the melting and mixing process. Instead of requiring complex purification steps, advanced spectroscopy for continuous monitoring, or multiple refining stages, the correction alloy chemically compensates for impurities, making specification compliance more achievable with simpler process control.
3Productivity
If large batches of metal alloys are produced, then productivity is improved, but contamination and manufacturing difficulties increase
Solution Approach 1:
The correction alloy acts as a consistency-maintaining intermediary that ensures uniform composition throughout large batches. By adding the correction alloy after melting the mongrel alloy, the process achieves homogeneous distribution of corrective elements throughout the bulk material, ensuring consistent properties across large production batches while maintaining the efficiency of batch processing.
4Manufacturing precision
If correction alloy is added to mongrel alloy, then composition accuracy and material properties are improved, but additional material and processing steps are required
Solution Approach 1:
The invention optimizes the correction alloy addition ratio within the range of 5-50 mass% of the mongrel alloy. This parameter optimization achieves the minimum effective correction level needed to compensate for contaminants and achieve desired material properties, thereby minimizing total material consumption while maintaining composition accuracy and avoiding unnecessary material waste.
