Effect of N2 on microstructure and mechanical properties of additive manufactured titanium matrix composites

More Information
  • 摘要: 鈦合金廣泛應用于航空航天、生物醫學等領域。但由于其力學性能不理想(如硬度低、耐磨性差)和加工性差,限制了其應用范圍。為了直接近凈成形出結構復雜且性能提升的鈦合金零部件。本文在選區激光熔化(SLM)Ti6Al4V鈦合金過程中通入氮氣(N2),通過Ti-N反應制備鈦基復合材料(TMCs)。該創新方法的成形原理為:激光誘導Ti6Al4V高溫熔池附近的N2分解生成N原子或者離子,并與熔融狀態的鈦原位反應生成TiN增強相,通過層層疊加,成形TiN增強鈦基復合材料。本文采用3種不同體積分數(3%、10%和30%)的N2氣氛SLM成形了鈦基復合材料,并對比了純氬氣(Ar)氣氛中SLM成形的Ti6Al4V鈦合金。采用掃描電子顯微鏡(SEM)觀察了材料的微觀組織。X射線衍射(XRD)圖譜表明部分N固溶進入Ti晶格中。能譜(EDS)證實了TiN的生成。高分辨透射電鏡(HR-TEM)圖進一步確認了基體相和第二相分別為Ti和TiN。這種原位合成的氮化物增強相分散均勻,尤其是在低體積分數N2氣氛(3%和10%)下制備的復合材料中均勻分布著大量納米級增強相。此外,在低體積分數N2氣氛(10%)下制備的復合材料強度和塑性同時提高。本文研究了不同N2濃度對鈦基復合材料微觀組織和力學性能的影響規律,并闡明了復合材料的強韌化機理。
