E-Mail Chinese scientists have made direct observations in face-centered cubic VCoNi (medium)-entropy alloys (MEA) and for the first time proposed a convincing identification of subnanoscale chemical short-range order (CSRO). This achievement undisputedly resolves the pressing question of if, what and why CSRO exists, and how to explicitly identify CSRO. This work, published in Nature on April 29, was conducted by Prof. WU Xiaolei from the Institute of Mechanics of the Chinese Academy of Sciences (CAS) in collaboration with Prof. MA En's team from Xi'an Jiaotong University and Prof. ZHU Jing's team from Tsinghua University. Multi-principal element alloys--also known as high (medium)-entropy alloys (HEAs/MEAs)--are a hot and frontier topic in multidisciplinary fields. In these HEAs/MEAs, enthalpic interactions among constituent elements may induce various degrees of local chemical order (LCO), of which CSRO is arguably the most difficult to decipher.
