两种细化剂复合应用对A356铝合金组织和性能的影响
Effect of the Composite Application of Two Refining Agents on the Microstructure and Properties of A356 Aluminium Alloy
摘要
Abstract
A new type of active Ti refining agent and Al-5Ti-B refining agent composite treatment of A356 aluminium alloy melt were used to study the two refining agent composite application of A356 aluminium alloy microstructure and properties of the impact.The results showed that adding active Ti refining agent on the basis of adding Al-5Ti-B refining agent could obviously improve the nucleation rate,refine α-Al grains and change the eutectic Si morphology.When adding 1％ Al-5Ti-B and 0.04％ active Ti refining agent,the α-Al phase was transformed from coarse dendritic to rosaceous and near-spherical,and eutectic Si morphology was changed from long-needle and plate sheet to sphere and short rod.The mechanical properties of A3 5 6 aluminium alloy were enhanced.The tensile strength,yield strength and elongation of A356 aluminium alloy with 1％ Al-5Ti-B and 0.04％ active Ti refiner were increased to 313 MPa,263 MPa and 12％,respectively.关键词
