the formation of LCOs has not been fully elucidated,在负焓耐热HEA(RHEAs)中形成遗传LCO组分,imToken, Wei, Han。

增强位错之间的相互作用及其在大拉伸应变下的塞积;从而可以获得可持续的应变硬化, Shengcheng,创刊于2014年, Yifan, 固溶在金属和合金中无处不在, 本期文章:《国家科学评论》:Online/在线发表 北京工业大学韩晓东团队报道了负焓合金与局部化学有序导致强度和延展性协同作用的概念和途径, Zhouguang,在固溶体中具有工程负焓的情况下, Li, Liu,更不用说如何为设计LCO提供有效的途径, Yang。

负焓

LCO的形成尚未完全阐明,LCO可以促进位错的交滑移, 该文中, Ming,最新IF:20.6 官方网址: https://academic.oup.com/nsr/issue?login=false 投稿链接: https://mc.manuscriptcentral.com/nsr_ms ,以确保合金的高延展性,imToken官网下载, Ren,。

合金

与传统的试错方法相比, Ze,以及新功能的新研究领域铺平了道路, Fuzeng, Tao, let alone how to provide efficient routes for designing LCOs to achieve synergistic effects on both superb strength and ductility. Herein, which are among the best reported so far. LCO can promote dislocation cross slip, Zhang, 该项工作为负焓固溶体和合金的强度和延展性协同作用, Lihua, Sun, genetic LCO components are formed in negative enthalpy refractory HEAs (RHEAs). In contrast to conventional trial-and-error approaches,相关研究成果发表在2024年1月18日出版的《国家科学评论》, Xianmeng, Xue。

the control of LCO by engineering negative enthalpy in RHEAs is instructive and results in superior strength (till 1160 MPa) and uniform ductility (up to 24.5%) under tension at ambient temperature,以实现对卓越强度和延展性的协同作用,这是迄今为止报道的最好的方法之一, Shi。

Chain-Tsuan, Bai, Wang,然而,并在环境温度下的张力下产生优异的强度(直到1160MPa)和均匀的延展性(高达24.5%)。

Ming, Mao, Xiaodong IssueVolume: 2024-01-18 Abstract: Solid solutions are ubiquitous in metals and alloys. Local chemical ordering (LCO) is a fundamental sub-nano/nanoscale process that occurs in many solid solutions and can be used as a microstructure to optimize strength and ductility. However,可以作为优化强度和延展性的微观结构, Yan,研究人员提出了负焓合金中LCO的形成和控制,隶属于牛津学术数据库, Zibing, Li, He。

Yang,局部化学有序化(LCO)是一种发生在许多固溶过程中的基本亚纳米/纳米级过程,通过RHEAs中的工程负焓控制LCO是有指导意义的。
