在材料科學中,"precipitated phase"(析出相)是指從過飽和固溶體基體中分離出來的、具有不同化學成分和晶體結構的第二相粒子。這一過程是強化金屬合金(如鋁合金、鎳基高溫合金、鋼等)的關鍵機制之一,稱為析出強化或時效強化。

“Precipitated phase”是一個材料科學和化學領域的專業術語,其含義可從兩個單詞的分解及組合來理解:
Precipitated(沉澱的)
該詞源自動詞“precipitate”,主要含義包括:
Phase(相)
在科學語境中指物質的物理狀态或結構形态,如固相、液相、氣相。此外,也可表示材料中具有特定成分和性質的區域。
組合含義
“Precipitated phase”指在材料(如合金或複合材料)中,通過物理或化學過程(如冷卻、熱處理)從基體中析出的新相。這種相通常以微小顆粒形式存在,可增強材料性能(如強度、硬度)。
示例應用:
在鋁合金中,通過時效處理析出的“θ相”(Al₂Cu)即為典型的沉澱相,可顯著提升合金強度。
如需進一步了解具體材料中的沉澱相類型,可參考材料科學相關文獻或專業詞典(如海詞詞典)。
