AI Technical Summary
Existing aluminum-scandium alloys exhibit rapid degradation of mechanical properties at high temperatures and suffer from poor melt flowability, hot cracking during crystallization, and anisotropic deformation during processing, making it difficult to meet the requirements for high-temperature service and processing.
By employing specific chemical composition formulations and refining processes, including the addition of trace amounts of Co and B, and the use of a high-temperature resistant, superrheological, in-situ impurity trapping and heterogeneous core self-assembly active composite refining agent, combined with multi-directional angle-adjusting cross deformation and three-stage aging treatment, the high-temperature stability, salt spray corrosion resistance, and conductivity of aluminum-scandium alloys are improved.
It significantly improves the mechanical properties and hardness of aluminum-scandium alloys at high temperatures of 300℃-350℃, reduces melt viscosity, decreases hot cracking during crystallization and anisotropy during processing, and enhances electrical conductivity and salt spray corrosion resistance.
