摘要:

鋯合金作為一種重要的戰(zhàn)略材料，被譽(yù)為“原子能時(shí)代的第一金屬”，由于其低中子吸收率、抗腐蝕、耐高溫等優(yōu)點(diǎn),被廣泛用作核反應(yīng)堆關(guān)鍵結(jié)構(gòu)材料。我國(guó)鋯合金基礎(chǔ)研究及工業(yè)化發(fā)展起步較晚，鋯合金種類較少，因此，鋯合金的研發(fā)受到了學(xué)術(shù)界及工業(yè)界的廣泛重視。回顧了核用鋯合金研發(fā)的歷史進(jìn)程、應(yīng)用現(xiàn)狀及未來(lái)發(fā)展趨勢(shì)，闡明了鋯合金基礎(chǔ)研究和開(kāi)發(fā)應(yīng)用的重要性，簡(jiǎn)要介紹了新興的高性能鋯合金，包括醫(yī)用鋯合金、耐腐蝕鋯合金、高強(qiáng)高韌鋯合金和鋯基非晶合金。隨著核反應(yīng)堆的升級(jí)換代和非核用應(yīng)用需求的多樣化，發(fā)展新型鋯合金、拓展鋯合金的應(yīng)用范圍，是鋯合金未來(lái)研發(fā)的著眼點(diǎn)。

Abstract:

Zirconium alloys, as an important strategic material, also widely known as “the first metal in the atomic-energy age”, are widely used in nuclear reactors as key structural components because of their small thermal neutron capture cross-section, excellent corrosion resistance and high-temperature mechanical properties. The fundamental research and industrialization of zirconium alloy in China is later than that of the developed countries. As a result, our zirconium industries have less variants of products, which attract broad attentions from the academic communities and industry sectors. In this review, we retrospect the development history, application status and future trends of nuclear-related zirconium alloys, and emphasize the importance of accelerating fundamental research and developing new zirconium alloys. The design and development of advanced high-performance zirconium alloys are also briefly introduced, including medical�瞮sed zirconium alloys, corrosion-resistant zirconium alloys, high strength-high toughness zirconium alloys and zirconium-based amorphous alloys. With the requirements of further upgrading of nuclear reactors and the diverse applications, the development of new zirconium alloys and the broadening of their applications are key points in future research & development of advanced zirconium alloys.
