I题目超声波对 A380 凝固行为的实验研究摘要传统导入方式的超声波处理虽然能够显著改善金属凝固组织和强化金属材料性能，但是由于存在诸多缺点，比如容易卷入夹杂物、对于高温合金的操作困难等，使得该技术在工业应用上有很大的难度。本文采用自主研发的“自吸式变幅杆”超声侧部导入技术，解决了超声波导入难题，并研究了该超声处理技术对铝基和铁基合金凝固特性、组织和性能的影响，探讨了其中的基础理论问题。为了探索超声波侧部导入处理工艺的可行性。本文通过实验分析超声波对 A380 凝固行为。关键词：超声波；A380；凝固IIABSTRACT Traditional ways of introducing ultrasonic treatment although can significantly improve the solidification structure of metals and metal materials to strengthen performance, but due to the existence of many shortcomings, such as easy to get caught up in inclusion, difficult operation to high-temperature alloy and so on, making the technique has great difficult in industrial applications. In this paper, the independent research and development of "self suction horn" ultrasonic side of import technology to solve the ultrasonic import problem, and to study the effect of the ultrasonic treatment technology of aluminum matrix and iron-based alloy solidification characteristics, microstructure and properties of, discusses the basic theoretical problems. In order to explore the feasibility of ultrasonic treatment technology. In this paper, the solidification behavior of A380 is analyzed by experiment.KEY WORDS: ultrasonic; A380; solidificationIII目录摘要......................................................IABSTRACT.................................................II引言......................................................11 相关概述................................................11.1 超声波处理技术..............................................................................................11.2 超声波中的金属熔体凝固..............................
