项目摘要
9707073 Voorhees Interfacial energy is the primary driving force for the precipitate coarsening processing metal alloys in the absence of elastic stresses. As a result, the average particle size increases monotonically with time, and large particles grow at the expense of small particles. In contrast, in the presence of elastic stress, particles can undergo inverse coarsening where small particles grow at the expense of large particles, and large-scale particle migration occurs in the solid. Complete stabilization of the two-phase mixture with respect to coarsening may be possible. In this research the coarsening process is examined in elastically stressed solids both experimentally and theoretically. The experimental effort focuses on two major unexplored aspects of the coarsening process in elastically-stressed solids: (1) the kinetics of the coarsening over a wide range of average particle sizes, from small average particle sizes, where the interfacial energy is the dominant energy in the system, to large particle sizes, where the elastic stress is the dominant energy in the system, and (2) the three-dimensional morphology and spatial arrangement of particles in the l ate stages of coarsening. The theoretical effort is directed toward predicting the evolution of a statistically large system of particles where the particle morphologies and locations evolve in a manner that is consistent with the elastic and diffusion fields in the system. This effort should allow the determination of statistically averaged quantities such as the exponents and amplitudes of the temporal power laws that describe the coarsening kinetics as well as the development of the microstructure during coarsening. %%% The theory will be used to predict the coarsening kinetics using parameters that will be measured in the experiments. The theory will be sufficiently realistic that the predictions can serve as a guide to the development of coarsening-resistant coherent alloys. * **
在没有弹性应力的情况下,Voorhees界面能是金属合金析出相粗化的主要驱动力。结果表明,平均粒径随时间单调增大,大颗粒的增大是以小颗粒的增大为代价的。相反,在弹性应力存在的情况下,颗粒会发生逆粗化,小颗粒以牺牲大颗粒为代价生长,并且在固体中发生大规模的颗粒迁移。就粗化而言,两相混合物的完全稳定是可能的。本研究从实验和理论两方面考察了弹性应力固体的粗化过程。实验工作集中在弹性应力固体中粗化过程的两个主要未探索的方面:(1)在较宽的平均粒径范围内的粗化动力学,从平均粒径较小(其中界面能是系统的主导能量)到大粒径(其中弹性应力是系统的主导能量);(2)粗化后期颗粒的三维形态和空间排列。理论上的努力是为了预测一个统计上大的粒子系统的演变,其中粒子的形态和位置以与系统中的弹性和扩散场一致的方式演变。这项工作应该允许确定统计平均量,如描述粗化动力学的时间幂律的指数和振幅,以及粗化过程中微观结构的发展。该理论将用于预测粗化动力学,使用将在实验中测量的参数。该理论将具有足够的现实性,其预测可作为抗粗化相干合金开发的指导。* * *
