中文摘要:
      采用径向锻复合单向压缩变形式再结晶熔融(RFCUC-RAP)法和径向锻复合多向压缩变形式再结晶熔融(RFCMC-RAP)法对铝合金6063挤压棒料进行处理。对比分析了合金在直接半固态等温处理(SSIT)法、RFCUC-RAP法及RFCMC-RAP法三种工艺下微观组织的演化过程。结果表明:相比于直接SSIT法,采用RFCUC-RAP法和RFCMC-RAP法制备出的铝合金6063半固态坯料的晶粒尺寸明显减小,晶粒形状也有所改善。同时,由于变形过程相对简单,RFCUC-RAP法比RFCMC-RAP法更有优势,是一种有效的制备高质量半固态坯料的方法。
Semi-solid Billet Prepared by Radial Forging Combined with Unidirectional Compression Recrystallization and Partial Melting

英文摘要:
      The Radial Forging Combined with Unidirectional Compression Recrystallization and Partial Melt (RFCUC-RAP) and Radial Forging Combined with Multi-axial Compression Recrystallization and Partial Melt (RFCMC-RAP) were proposed to prepared semi-solid billet. The microstructural evolutions of semi-solid 6063 Al alloy prepared by direct semi-solid isothermal treatment (SSIT), RFCUC-RAP and RFCMC-RAP were investigated. Results show that, the solid grains of semi-solid billet prepared by direct SSIT are large. However, solid grains of semi-solid billet prepared by RFCUC-RAP and RFCMC-RAP are fine and spherical. Additionally, the RFCUC-RAP is superior to the RFCMC-RAP owing to the relatively simple deformation process, which is an effective method to prepare high-quality semi-solid billet.
