西工大《Mater Des》:TA15鈦合金熱加工過程的應變局部化
相關論文以題為“Microstructure dependent strain localization during primary hotworking of TA15 titanium alloy: Behavior and mechanism”發表在Materials and Design。 論文鏈接: https://doi.org/10.1016/j.matdes.2021.109589 本研究使用的材料為工業應用的TA15鈦合金,初始材料為熱鍛造合金,具有典型的等軸組織,β基體內約含有50%的初始等軸 α 相和20%的層狀α相。相變溫度約985℃。為了獲得層狀組織,進行1020℃×60min退火(爐冷),熱加工選擇帽形試樣熱壓縮(以10K/s的升溫速率加熱至1073K,均勻化3min,以0.1s-1的應變速率變形,水冷)。 研究表明,基體內部相的發展有三個關鍵階段:(1)各組成相之間被迫均勻變形階段,表現為α相和β相之間的應力梯度增加,伴隨著α片層內α位錯塞積加劇;(2)層間尺度上集中變形階段,其始于突然發生且高度局部化的相界面減弱而引起的應力梯度崩潰,然后在弱化點處產生干擾促使片層向更軟的方向旋轉;(3)在基體內明顯的定位階段,粗滑移帶的收斂和快速傳播。 圖1 變形前的微觀組織結構 圖2 變形后橫截面的微觀結構 圖3 橫截面上剪切帶內部顯微組織的TEM圖 由于應變分配的各向異性行為,揭示了應變局部化取決于層狀取向。對于其中可以充分激活應變分配的層狀取向,很難實現強制均勻變形的第一階段,從而阻礙了應變局部化。

北科大《MSEA》:3D打印納米增強高Nb-TiAl合金
該研究以題為“Electron beam melted TiC/high Nb–TiAl nanocomposite: Microstructure and mechanical property”發表在Materials Science and Engineering A。 論文鏈接: https://doi.org/10.1016/j.msea.2021.141059 本研究在EBM的預熱和熔化步驟中間增加了半熔化過程,極大程度抑制了“吹粉”現象,提高了制備工藝的穩定性。 得到的成形態樣品內部沒有未熔合和孔洞等缺陷,具有高的致密性。對EBM樣品頂層和心部顯微組織進行觀察后發現,在EBM制備過程中,納米TiC發生溶解,Ti2AlC相通過初始凝固過程中的完全包晶反應和后續熱循環過程中的析出作用形成,并以近球形和棒狀彌散分布在TiAl基體中。這些碳化物對TiAl基體的凝固和組織退化過程有明顯影響,促使TiAl基體由近片層組織向細化的雙態組織轉變。另外,在面能量密度恒定的條件下,采用低掃描速度和高線間距的樣品具有更高的相對密度、Al損和α2相體積分數以及更低的碳化物含量。
