摘要:

為了克服現(xiàn)有的高能束金屬快速成形與制造工藝的局限性，近年來人們發(fā)展了超聲波金屬疊層結構快速固結成形與制造的技術，該技術采用大功率超聲能量，以金屬箔材為原材料，利用金屬層間振動摩擦產(chǎn)生的熱量，促進層間金屬原子相互擴散和形成固態(tài)物理冶金結合的界面，且具有溫度低、變形小、速度快、綠色環(huán)保等優(yōu)點，適合于復雜疊層零部件成形、加工一體化智能制造，是一種新型的增材制造3D打印技術。簡要介紹了超聲波金屬疊層結構快速固結成形與制造這一先進增材制造技術的應用，主要綜述了現(xiàn)有的Al/Al、Cu/Cu、Ti/Al等同種和異種金屬疊層系統(tǒng)工藝參數(shù)優(yōu)化方面的研究成果，著重分析了超聲波固結成形金屬物理冶金的微觀機理和界面性能的表征技術。在此基礎上，針對目前超聲波金屬固結成形機理研究的現(xiàn)狀提出了有待深入研究的內容。

Abstract:

In order to overcome the limitations of the high energy beam rapid prototyping and manufacturing processes, high power ultrasonic consolidation and manufacturing technique was developed in recent years. Metal foils were bonded together using very high ultrasonic energy and metal atoms were heated up by very high frequency vibration diffused from one phase surface to another to form a metallurgical solid-state combination. Compared with other rapid prototyping techniques, high power ultrasonic consolidation and manufacturing technique owns many advantages, such as low temperature, less deformation, high consolidation speed,and environment friendly, which can be used for the intelligent manufacture of integrated consolidation and machining for complex laminated metal parts. As mentioned above, it is a novel additive manufacturing 3D printing technique. This paper briefly introduces the advanced Ultrasonic Additive Manufacturing (UAM) technique and mainly reviews the achievements of the optimal process parameters of similar and dissimilar metal laminate materials(Al/Al, Cu/Cu, Ti/Al, etc.), then focuses on analyzing the microscopic physical metallurgy mechanism of metal ultrasonic consolidation and characterization techniques of interfacial properties. Based on the current study status of ultrasonic consolidation mechanism, some research aspects needed to further investigate are also pointed out in this work.
