Problems solved by technology

[0004] Materials genome engineering mainly includes three parts: high-throughput material calculation, high-throughput material experiment and database. As a key technology in the high-throughput material experiment method, the diffusion multi-component has been widely used in the high-throughput analysis of alloy components and tissue samples. Quantitative preparation, but this method is based on the solid / solid diffusion phase transition process, which cannot achieve high-throughput preparation of the composition and structure of the alloy liquid / solid phase transition process, and adopts a high-throughput preparation technology based on the liquid / solid phase transition process , can effectively enrich the high-throughput preparation technology, and further reduce the R&D cost and cycle

Abstract

The invention relates to the technical field of high-flux preparation in a material genome plan, in particular to a high-flux preparation method of a high-temperature alloy material. The method comprises the following steps: (1) injecting molten wax into a metal mold through a wax injection machine; (2) sticking an adhesive tape to a position surface where a metal block or an alloy block is placed; (3) sintering a combined wax mold into a corundum mold shell; (4) placing the metal block or alloy block into the corundum mold shell, and sealing the corundum mold shell with corundum powder; (5) placing the corundum mold shell into a directional solidification furnace for directional solidification. The method has the characteristics of being simple in preparation process, low in cost and thelike; the limitation that diffusion of multiple elements can only realize solid / solid phase-change high-flux preparation of a composition tissue sample is broken through, but cannot realize high-fluxpreparation of a composition tissue sample, particularly a eutectic reaction tissue, during solidification of an alloy turning from a liquid phase to a solid phase is broken through. The method can realize the high-flux preparation of a solid / liquid phase-change tissue sample, and is favorable for research and development of the high-temperature alloy material.

Description

Technical field: [0001] The invention relates to the technical field of high-throughput preparation in the material genome project, and specifically relates to a high-throughput preparation method for superalloy materials. Background technique: [0002] Superalloys are key materials for manufacturing hot-end components of aero-engines, and the performance of superalloys plays a key role in aero-engines. With the increase of engine air inlet temperature, higher requirements are placed on the performance of superalloy materials, so it is urgent to develop new superalloy materials with higher temperature bearing capacity. In the design process of superalloy composition, an important idea is to add a large amount of refractory metal elements such as Ta, Mo, W, Re and Ru to improve the temperature bearing capacity of the alloy. [0003] However, the increase of refractory elements will lead to the formation of a large number of harmful topologically closed packed phases (Topolog...
