Coherent Precipitation and Strengthening in Compositionally Complex Alloys: A Review [PDF]
Entropy, 2018 High-performance conventional engineering materials (including Al alloys, Mg alloys, Cu alloys, stainless steels, Ni superalloys, etc.) and newly-developed high entropy alloys are all compositionally-complex alloys (CCAs).

Nucleation pathway in coherent precipitation [PDF]
Philosophical Magazine, 2011 The non-classical nucleation pathway of coherent precipitates has been computed through the minimisation of the nucleation barrier in the composition (c) - size (R) space so that to predict the evolution of the nucleus composition. The generalized Gibbs model developed by Schmelzer et al.

Large-scale circulation shapes the spatial organization of anomalous precipitation over Northern Jiangsu [PDF]
iScienceSummary: Anomalous precipitation events often exhibit coherent spatial organization rather than isolated intensity extremes, reshaping regional flood risk in subtropical monsoon zones.

On the theory of strengthening by coherent ordered precipitates [PDF]
Philosophical Magazine Letters, 1990 Abstract This paper contrasts recent discussions of the theory of strengthening by coherent precipitates. The most important difference is in the assumed condition at maximum hardness. In one treatment, the maximum hardness is reached when dislocations first begin to loop precipitates, and is hence controlled by the largest particles in the precipitate

Effect of boron on aging strengthened phase and properties of Cu–Cr–Zr alloy
Journal of Materials Research and Technology, 2022 The effect of trace B on the properties and microstructure of Cu–Cr–Zr alloy was investigated in this work. Aging precipitation phases in Cu matrix were analyzed by transmission electron microscopy (TEM) and high-resolution transmission electron ...
