Description

Technical Field

[0001] This utility model relates to the field of single crystal alloy processing technology, specifically to a specific crystal plane cutting fixture for single crystal high-temperature alloys. Background Technology

[0002] Nickel-based single-crystal superalloys possess excellent resistance to high-temperature creep and high-temperature mechanical properties, and are widely used in the manufacture of core hot-end components for advanced aero-engines and gas turbines. Due to their face-centered cubic (FCC) structure, the anisotropy of the FCC unit cell causes the alloy to exhibit anisotropic microstructure and mechanical properties under high-temperature stress. Therefore, the different deformation mechanisms caused by anisotropy have become a key research focus in this field. Currently, many researchers have conducted anisotropic studies by directly preparing single-crystal superalloy specimens with different crystal orientations. However, in practice, it is difficult to cut samples with specific crystal faces from single-crystal specimens that have been interrupted or fractured due to creep or fatigue.

[0003] The utility model with publication number CN218694673U discloses a rotating angled cutting bevel plate, which can perform sample rotation cutting, but cannot quantify the rotation angle.

[0004] The invention disclosed in publication number CN104846441B discloses a method for cutting and preparing nickel-based single crystal alloy seed crystals for casting. The method uses an X-ray stress measuring instrument to cut and mark the sample, but the steps are cumbersome, the orientation deviation of the sample is large, and the sample preparation cost is high.

[0005] Therefore, this invention proposes a specific crystal plane cutting fixture for single-crystal superalloys, which facilitates accelerated testing and promotes the study of anisotropy in single-crystal superalloys. Utility Model Content
