ABSTRACT: Material Genome Engineering (MGE), which changes the traditional sequential iteration method to parallel processing, is a novel technique of materials research. High-throughput preparation technology, an important part of MGE, can realize the preparation and screening of a large number of samples in a short time. This study is based on the theories of powder metallurgy and thermal diffusion to manufacture the third generation of honeycomb-array sleeve. The relationship of content, microstructures and properties was studied by the high-throughput Hot Isostatic Pressing (HIP) micro-synthesis of bulk combinatorial materials.

This paper focused on the problems found in the research of the second generation of honeycomb-array sleeve, such as irregular shapes of honeycomb-array sleeve after HIP, outward diffusion of Ti in honeycomb-array sleeve after HIP and Non-integral honeycomb-array sleeve. Then the third generation of honeycomb-array sleeve was developed. We will introduce the preparation of the third and the alloys which is Ni base superalloys with multi-components. It showed that the third, which had been calculated by finite element simulation, had effectively improved the irregular shape of honeycomb-array sleeve caused by HIP. And because of 3D printing, the third is a whole. What’s more, the thermal barrier coating applied in the honeycomb prevents the diffusion of the covering material into the mixed powder in the honeycomb holes, so that ensured the purity of mixed powder materials. At the same time, the third can prepare maximum 106 different alloys once time, while the second can prepare 85 different alloys.

The results showed the high-throughput HIP micro-synthesis of bulk combinatorial materials was optimized, while providing basis for High-throughput characterization.
