SPP 1713: Strong Coupling of Thermo-Chemical and Thermo-Mechanical States in Applied Materials

许多应用材料，如金属和固态聚合物，由多个相组成。它们的性质主要取决于内部相结构，即，相的分数和局部分布、它们的组成和它们的分子构型。化学方面影响机械性能以及机械载荷耦合回化学。这种强烈的相互关系表示在材料的热力学泛函中，该热力学泛函一方面由热化学或热溶质部分组成，另一方面由依赖于温度的机械部分组成。化学和力学在应用材料中的相互作用是优先计划的中心目标。

Many applied materials like metals and solid-state polymers consist of multiple phases. Their properties depend crucially on the internal phase-structure, i.e., the fraction and local distribution of the phases, their composition and their molecular configuration. Chemical aspects influence the mechanical properties as well as mechanical load couples back to chemistry. This strong interrelation is expressed in the thermodynamic functional of the material, which is composed of a thermo-chemical or thermo-solutal part, on the one hand, and a temperature-dependent mechanical part, on the other hand. The mutual interaction between chemistry and mechanics in applied materials is the central goal of the Priority Programme.
