摘要:

隨著微納米科學(xué)和微機(jī)電系統(tǒng)（Micro-Electro-Mechanical Systems, MEMS）技術(shù)的快速發(fā)展，對微型零件的需求日益增加。塑性微成形是一種采用塑性變形方法成形零件尺寸至少有兩個(gè)方向在亞毫米量級的微制造方法，具有加工效率高、工藝簡單以及成形零件性能優(yōu)異和精度高等特點(diǎn)，特別適合于微型零件的低成本批量制造。本文介紹了塑性微成形技術(shù)的研究背景、應(yīng)用領(lǐng)域及其優(yōu)點(diǎn)，綜述了微成形在尺度效應(yīng)、新設(shè)備以及工藝方法等方面的最新研究進(jìn)展，并論述了微成形技術(shù)在新材料(超細(xì)晶材料及非晶材料)方面的發(fā)展趨勢。

Abstract:

With the rapid development of micro/nano science and micro-electro-mechanical systems (MEMS) technology, the requirements for micro-parts are quietly increased. Micro-forming is a manufacturing method using plastic deformation for the production of parts having at least two dimensions in the sub-millimeter range. Micro-forming becomes an attractive option in the manufacturing of micro products with high efficiency, simple process, excellent properties and high accuracy because of its advantageous characteristics for mass production with low cost. The background, application and advantages of the micro-forming are presented. The state of the art in micro-forming is summarized from the viewpoint of size effect, novel micro-forming machine, forming processes and methods. Finally, the development trends of micro-forming technology with new materials, such as ultrafine-grained materials and bulk amorphous alloys, are discussed.
