摘要
运用双辊快速凝固方法将液态Ａｌ－１２．６％Ｓｉ合金直接制备成厚度为０．１～０．５ｍｍ的薄带。介绍了这一方法的基本原理、特点和试验设备设计中的关键问题。辊面可控线速度Ｖｒ为２～８．５ｍ／ｓ，薄带厚度正比于Ｖｒ－１／２。薄带组织为细小的初晶α－Ａｌ和极细小的（α－Ａｌ＋Ｓｉ）共晶体。
Al126%Si strips with 01 to 05mm thickness have been produced directly from the melt by doubleroller rapid solidification processThe mechanism and characteristics of this method and key points related to design of the experimental apparatus have been describedThe roll surface velocity V5BZ]r ranged from 2 to 85m/sIt was shown that the strips thickness was proportional to V r-1/2 and that the microstuctures of the strips were composed of fine primary Al phase and very fine eutectic grains of Al and SiTensile strength and plasticity of the strips were greatly improved
