Deformed Al-Mn series alloy and preparing process thereof

Abstract

A deformable Al-Mn alloy contains Si (0-0.6%), Fe (0-0.7%), Cu (0-0.3%), Mn (0.3-1.6%), Mg (0-1.3%), Ti (0.005-0.15%), RE (0-0.4%), B (0-0.03%), impurities (0-0.7%) and Al (rest). Its preparing process includes such steps as smelting fine-crystal Al ingot, adding others, smelting Al-Mn alloy, and pressure machining.

AI Technical Summary

Benefits of technology

This patented new type metal material has several technical benefits: it can be produced at lower cost by making small pieces from finely grained raw materials like Al or Mg instead of expensive pure metals such as gold (Gold) powder). It also improves its quality through better control over crystal growth during casting processes compared with traditional methods that use purified molten salts for forming the desired microstructure.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving the quality and efficiency of making finer-grainy metallic products from aluminums such as silicon-, tantalum-, bismuth-, copper-bearthoxygen sulfur compounds. Current methods for crushing these powders result in impurities like iron particles, leading to decreased product yield due to contamination issues. To address this issue, new techniques have been developed involving melting and casting into thin sheets instead of forming them separately. However, there remains challenges related to achieving complete homogeneity within each sheet while maintaining sufficient particle size distribution throughout.
