摘要:

規(guī)�；瘧�用促使金屬基復合材料研發(fā)向更高強度、良好塑韌性和工藝性邁進。圍繞該目標，近年來的研究重點主要以多尺度強化、納米碳材料增強以及非均質(zhì)構(gòu)型設計等為特點。本文介紹了相關(guān)的研究進展，指出超細晶、超細顆粒協(xié)同強化可以獲得高強度與良好塑韌性，進一步通過雙尺度增強相強化可以兼顧模量等綜合性能；納米碳材料綜合性能極高，對金屬的強化具有高效與多樣化特性；非均質(zhì)構(gòu)型在充分發(fā)揮納米碳和陶瓷相的增強作用、挖掘復合材料性能極限方面體現(xiàn)了極高的可行性。同時也指出這些研究面臨的挑戰(zhàn)，未來有必要開展構(gòu)型仿真、納米碳-金屬界面模擬研究以及發(fā)展必須的宏量制備技術(shù)。可以預見，金屬基復合材料的研發(fā)已經(jīng)進入新階段，并已成為高性能材料發(fā)展的一個重要方向。

Abstract:

Metal matrix composites are developed toward higher strength, good ductility or toughness and high performance in order to meet demand of a wide application. For this purpose, attempts have been focused on multi scale strengthening, nano carbon reinforcing and architecture design. A review on the present research indicates that the synergetic strengthening of ultrafine grains and reinforcing particles could provide high strength and good toughness. Based on that, addition of dual-scaled reinforcements is effective for improvement of comprehensive properties  such as the elastic modulus. The nano carbon reinforcements are highly effective and multiple for strengthening metals due to their ultrahigh mechanical and physical properties. As to the hierarchical architecture, it is highly feasible for effectively strengthening metals without sacrificing ductility and toughness. Challenges for these studies are addressed. In the future, modelling and simulation for architecture and interface between nano carbons and metals should be conducted. Furthermore, novel fabrication methods for mass production should be developed. Research of metal matrix composites has entered a new era, and it is one of important branches of novel materials.
