Tribochemically Driven Carbon Release Lubrication in Zr‐Incorporated (Ti,Nb) 2 AlC via Selective M─C Bond Cleavage

Cheng‐Feng Du, Shiyao Lei, Conghui Meng, Yifei Xiao et autres

ABSTRACT Benefiting from the heterodesmic bond character, MAX phase ceramics are promising candidates for integrating mechanical and self‐lubricating properties under harsh conditions. However, the robust M─C bonds cause hard metal carbide debris on worn surfaces, resulting in a persistently high coefficient of …

Intelligent Early Warning and Decision Support for Power Grids Based on the Hybrid Model of Isolation Forest and LightGBM

Churan Deng, Peng Pang, Hui Pan, Shuang Zhao et autres

The monitoring data of modern power grids are characterized by being multi-dimensional, massive, and requiring high timeliness. Early warning methods based on thresholds or simple statistical models struggle to handle faint, early-stage anomalies under complex operating conditions, often leading to delayed or …

Effect of Al segregation on dislocation transmutation across {101¯2} twin boundaries in Mg: An atomistic simulation study

Lang Liu, Xuan Luo, Konstantinos Papadikis, Yunchang Xin et autres

Atomistic simulations were adopted to study the solute segregation effect on dislocation transmutation across the {101¯2} twin boundaries in magnesium. For pure magnesium, the dislocation-twin reaction resulted in the formation of sessile dislocations accompanied by the fast migration of the twin boundary, …
