Effect of in situ TiC Particulate on the Microstructure of Spray Deposited Al-20Si-5Fe Alloy

State Key Laboratory for Advanced Metals Materials, UST Beijing, Beijing 100083, China

摘要: 利用熔鑄-原位反應噴射沉積成形技術制備了TiC顆粒增強A1-20Si-SFe復合材料.分析了內生TiC顆粒對噴射沉積Al-20Si-5Fe合金微觀組織的影響.結果表明:噴射沉積A1-20SI-5Fe合金微觀組織中常出現脆性、針狀的A1-SI-Fe三元金屬間化合物相.在A1-20Si-5Fe合金中內生一定量的TiC顆粒,有助于減小粗晶Si顆粒的尺寸、消除針狀的A1-Si——Fe三元金屬間化合物相.

Abstract: A TiC/A1-20Si-5Fe composite is fabricated by melt in situ reaction spray forming and effect of in situ TiC particulate on the microstructure of spray-deposited Al-20Si-5Fe alloy is studied. Both theoretical and experimental results have shown that some Al-Si-Fe intermetallic phases with needle-like structure exist in the spray-deposited Al-20Si-5Fe alloy, which is harmful to the tensile properties of the composites. The needlelike intermetallic phases can be entirely absent in the final product after 5%Tic (mass fraction) particulates are in situ formed in spray-deposited Al-20Si-5Fe alloy.
