MAX phases: Bridging the gap between metals and ceramics
American Ceramic Society bulletin, v 92(3), pp 20-27

Abstract
An overview is given of the properties and current understanding of the MAX phases. Some of their potential applications are highlighted. The term "MAX phases" was coined in the late 1990s and applies to a family of 60+ ternary carbides and nitrides with a layered structure. Their chemical formula is Mn+1AXn, where n = 1, 2 or 3, M is an early transition metal, A is an A-group element (the subset of elements 13-16) and X is carbon and/or nitrogen. Research into these phases has rapidly increased since 1996, with around 1200 papers published on one MAX phase alone, Ti3SiC2. They have unusual, often unique, properties; like binary carbides and nitrides, they are elastically stiff, are good thermal and electrical conductors, resistant to chemical attack and have relatively low CTEs. However, they are relatively soft and most are readily machinable, thermal shock resistant and damage tolerant; some are also fatigue, creep and oxidation resistant. They have good load recovery at RT, and undergo a brittle-to-plastic transition at higher temperatures. [Cover story]
