摘要:

金屬間化合物因其原子的長(zhǎng)程有序排列及原子間的強(qiáng)鍵合而具備介于金屬和陶瓷之間的獨(dú)特性質(zhì)，尤其是最近興起的化學(xué)復(fù)雜型金屬間化合物在結(jié)構(gòu)和功能特性方面取得了顯著突破，并獲得了廣泛的關(guān)注。得益于有序超點(diǎn)陣結(jié)構(gòu)與多種元素化學(xué)性質(zhì)的協(xié)同調(diào)節(jié)作用，這些化學(xué)復(fù)雜型金屬間化合物有望表現(xiàn)出超越傳統(tǒng)金屬間化合物的非凡性質(zhì)與性能。主要針對(duì)化學(xué)復(fù)雜型金屬間化合物的晶體結(jié)構(gòu)、材料設(shè)計(jì)、成形工藝和各方面性能進(jìn)行了總結(jié)，重點(diǎn)關(guān)注材料設(shè)計(jì)中涉及的元素占位偏好、亞點(diǎn)陣高熵效應(yīng)和晶界納米無(wú)序等問(wèn)題，并對(duì)當(dāng)前這一新型金屬間化合物材料的先進(jìn)制備工藝、結(jié)構(gòu)和功能性能的最新進(jìn)展進(jìn)行了概述。最后，對(duì)化學(xué)復(fù)雜型金屬間化合物的未來(lái)發(fā)展方向作出了展望。

Abstract:

Intermetallic compounds possess unique properties between metals and ceramics due to their long-range ordered arrangement of atoms and strong interatomic bonding, especially, the recently emerged chemically complex intermetallic compounds have made remarkable breakthroughs in structural and functional properties and gained wide attention. These chemically complex intermetallic compounds have great potential to exhibit extraordinary properties and performance beyond conventional intermetallic compounds due to the synergistic modulation of the ordered superlattice structure and the chemical properties of multiple elements. This paper summarizes the crystal structure, material design, manufacturing process, and various aspects of properties of chemically complex intermetallic compounds, focusing on the elemental occupancy preference, sublattice high entropy effect, and grain boundary nanoscale disordering involved in the material design, and gives an overview of the recent advances in the advanced manufacturing process,structural and functional properties of this new type of intermetallic compound materials. Finally, the future development of chemically complex intermetallic compounds is envisioned.
