In this paper, we propose a novel region-based fractal grain-oriented YSZ micrograin, which was designed with the double primary grain-orientation of the grain-oriented YSZ MGs of GBs < 90 and < 120 degrees. Radiation damage tests of these YSZ MGs prove that both of them present excellent radiation resistance of being used in nuclear power area.
This paper studies fractional calculus (FC) atomization models (ACM) with a target of producing growth of the dendrite-tree morphology. The relationship between the FC models and ACM is also discussed. Laboratory experiments are performed to evaluate the validity of fractal theory and the results demonstrate the feasibility of fractal morphology. This model can be used to improve the mechanical properties of dendrite grain-oriented structure by modulating grain-oriented microstructure of dendrite grain-oriented structure. It is also a new class of ACM that can be used to build the dendrite-tree of metal materials.
In the latter part of this paper, we propose a new class of ACM with a target of producing a new class of particle growth of the morphology. It is also proven that the FC model can be used to improve the mechanical properties of metal materials. According to the influence of critical edge length on the morphology of particle growth, we can generate a variety of particle morphologies, that is, the morphology of the proposed ACM is stable and the morphology of the particle is controllable, which has not been reported in previous literatures previously. Experimentally, the morphologies of two kinds of particles are reproduced to prove that the model is feasible.
The proposed model has been adopted to produce the primary and secondary-phase distribution, which enables the primary and secondary phases to form the desired nanoscale distribution of the alloy component. d2c66b5586
