化学有序MAX相的研究进展
Research progress of chemically ordered MAX phases
摘要
Abstract
Layered transition metal carbide MAX phases combine the high electrical and thermal conductivity of metals with the high modulus,high-temperature mechanical properties,and oxidation resistance of ceramics,making them promising for applications such as high-temperature structural components and electronic devices.To overcome the performance limitations of conventional single-transition-metal MAX phases,chemically ordered MAX phases formed through alloying strategies have become a research focus.Based on the spatial site occupancy of transition metal atoms,chemically ordered MAX phases can be classified into two types:in-plane chemical ordering(i-MAX)and out-of-plane chemical ordering(o-MAX).This review summarizes the structural characteristics,formation principles,and the mechanisms by which these two types of chemically ordered MAX phases influence physical and mechanical properties.In i-MAX phases,the introduction of Group IIIB elements Sc,Y,lanthanide rare-earth atoms or Zr leads to ordered occupancy of M''atoms within the c-plane,resulting in degradation of crystallographic symmetry and the formation of various structures such as monoclinic or orthorhombic,accompanied by tunable magnetic ground states and significantly enhanced hardness.In o-MAX phases,different M''atoms stack alternately along the c-axis on specific atomic planes,and their formation is governed by the interplay of electronegativity,atomic radius,and carbide configuration,exhibiting excellent compressive strength and tunable anisotropic bonding characteristics.This review analyzes the mechanisms by which chemically ordered structures regulate the properties of MAX phases and discusses the existing challenges and future directions in this field,aiming to provide a reference for the design of high-performance MAX phases.关键词
