SPP 1296: Heterogeneous Nucleation and Microstructure Formation: Steps towards a System- and Scale-bridging Understanding

该优先计划的目标是对异质成核的基本机制以及核随后发展为特定异质微观结构的基本机制有一个基本的了解。特别是，一个系统和方法的跨越科学方法的目的是有助于详细的，多尺度的了解这些机制，这是为了连续和系统独立地应用于不同种类的材料系统。最初，这是计划为最简单类型的模型系统的异质晶体订单，纯金属，二元金属合金和胶体。它们的液相是结晶成核的基础，应通过检查其物理性质和有序特性来规定。更具体地说，打算在优先方案范围内探讨以下问题：

The goal of this Priority Programme is to attain a fundamental understanding of the basic mechanisms underlying heterogeneous nucleation as well as the subsequent development of the nucleus into a specific heterogeneous microstructure. In particular, a system and method-spanning scientific approach is intended to contribute to a detailed, multiscale understanding of these mechanisms, which is intended to be applied successively and system-independently on different kinds of material systems. Initially, this is planned for the simplest types of model systems for heterogeneous crystalline orders, for pure metals, binary metal alloys and colloids. Their liquid phase, which is the basis for crystalline nucleation, shall be specified via examinations of its physical properties and ordering characteristics. More specifically, the following questions are intended to be explored within the context of the Priority Programme:
