此篇研究以氣體霧化法製備成分均勻，並篩選出粒徑為 10-60 µm 的 AlCrFeNiSi 高熵合金粉末，並與光固化樹脂混合成 60 vol.% 可光固化之複合漿料，導入數位光處理 3D 列印技術製成 AlCrFeNiSi 高熵合金複合材料，並進一步探討此零件於後續不同熱處理條件中，界面元素擴散對其機械性質之影響。
　透過數位光處理列印成功製備 AlCrFeNiSi 高熵合金複合材料，在後續以不同溫度燒結後可以觀察到，大氣與真空環境脫脂樣品，隨溫度升高，粉末距離縮小，且分別於 1100°C 與 1050°C 時，側面層狀結構消失，堆疊變得緻密，真空環境脫脂樣品，碳促進元素間擴散行為，使得在 1100°C 燒結溫度中，小粉末熔融附著於大粉末表面形成條狀物。
　　在機械性質方面，隨著燒結溫度從 800°C 增加至 1100°C，真空環境脫脂樣品抗壓強度由 2.4 MPa 上升至 5 MPa，大氣環境脫脂樣品抗壓強度由 0.5 MPa 上升至 5.1 MPa，整體而言，真空環境脫脂樣品有著較大氣環境脫脂樣品更高的強度，在後續燒結處理過程中，碳作為有效的間隙合金元素之一，由於碳空位相互作用，加速元素的擴散躍遷，誘導 AlCrFeNiSi 高熵合金元素在較低溫燒結溫度便完成擴散，同時促使粉末間介面消失提高了鍵結力與結合度。

　　In this study, AlCrFeNiSi high-entropy alloy powder with a uniform particle size of 10-60 μm was prepared by gas atomization method, and mixed with photocurable resin to form a 60 vol.% photocurable composite slurry, which was introduced into digital light processing 3D The AlCrFeNiSi high-entropy alloy composite material was made by printing technology, and the effect of interfacial element diffusion on the mechanical properties of this part in different subsequent heat treatment conditions was further explored.
　　The AlCrFeNiSi high-entropy alloy composite material was successfully prepared by digital light processing and printing. After sintering at different temperatures, it can be observed that the debinding samples in the atmosphere and vacuum environment, as the temperature increases, the distance between the powders shrinks, and respectively at 1100 ° C and At 1050 °C, the side layer structure disappeared and the stacking became dense. The sample was debinded in a vacuum environment, and carbon promoted the diffusion behavior between elements, so that at the sintering temperature of 1100 °C, the small powder fused and attached to the surface of the large powder to form strips.
　　In terms of mechanical properties, as the sintering temperature increased from 800°C to 1100°C, the compressive strength of the debinded sample in a vacuum environment increased from 2.4 MPa to 5 MPa, and the compressive strength of the debinded sample in an atmospheric environment increased from 0.5 MPa to 5.1 MPa. , the debinding sample in a vacuum environment has higher strength than the debinding sample in the atmospheric environment. In the subsequent sintering process, carbon is one of the effective interstitial alloying elements. Due to the interaction of carbon vacancies, the diffusion transition of elements is accelerated, and the AlCrFeNiSi high-entropy alloy is induced elements diffuse at a lower sintering temperature, and at the same time promote the disappearance of the interface between powders and improve the bonding force and degree of bonding.
