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

这一优先方案的目标是从根本上了解非均质成核的基本机制以及随后核发展成特定的非均质微结构的过程。特别是，一种跨越系统和方法的科学方法旨在促进对这些机制的详细、多尺度的理解，其目的是在不同类型的材料系统上连续和独立地应用。最初，这是为纯金属、二元金属合金和胶体的非均质结晶有序的最简单类型的模型系统而计划的。它们的液态是结晶成核的基础，应通过检查其物理性质和有序性来确定。更具体地说，拟在优先方案的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:
