Parameter Optimization in High-Throughput Testing for Structural Materials

Abstract

High-throughput screenings are established evaluation methods in the development of functional materials and pharmaceutical active ingredients. The transfer of this approach to the development of structural materials requires extensive adaptations. In addition to the investigation of new test procedures for the determination of material properties and the treatment of metallic materials, the design of experiments is a research focus. Based on given descriptor target values, the statistical design of experiments determines investigations and treatments for the investigation of these materials. In this context, process parameters also have to be determined, as these have a major influence on the later material properties, especially during the treatment of samples. In this article, a method is presented which determines the process parameters iteratively. The validation of the calculated process parameters takes place based on differential scanning calorimetry used as the furnace for the heat treatment of small batches and particle-oriented peening as the characterization method.

Multiscale Material Characterization Based on Single Particle Impact Utilizing Particle-Oriented Peening and Single-Impact Peening

“…A newly established set-up was used for both the particle-oriented and the single-impact peening. It allows to process a large number of particles in a highly defined and reproducible way [19,20,23]. In both cases the particles are accelerated with compressed air (jet pressure p s = 4 bar) to impact on a contact plate which is located at a constant distance of a = 80 mm in front of the nozzle outlet.…”
