【正文】 ing matrix. Fig. 2. TEM micrographs and corresponding diffraction patterns of the AA2324 alloy in the WQ270 condition: (a) bright field。 (b) [0 0 1]Al SAD pattern of the S phase precipitate in dark contrast in (a) with surrounding matrix (the streaks emanating from the brighter Al spots are an artefact due to camera saturation)。 (c) simulated SAD pattern corresponding to (OR1). The rectangle corresponds to the range of (b). 位錯運動的動態(tài)電子顯微鏡觀察 左：具有最大襯度的刃位錯像 g∥ b 右：位錯襯度趨于零 g⊥ b 多相合金的衍射和襯度效應(yīng) 第二相的衍射效應(yīng) （相界面） 共格 半共格 非共格 平行于電子束的片狀沉淀產(chǎn)生的倒易桿 在 s=0時可以看到條紋 s≠0時可以看到偽衛(wèi)星斑點 圖 Moir233。 條紋形成原理圖 (a)平行Moir233。 條紋 (b)旋轉(zhuǎn) Moir233。 條紋 (c)通常 Moir233。 條紋 謝謝觀看 /歡迎下載 BY FAITH I MEAN A VISION OF GOOD ONE CHERISHES AND THE ENTHUSIASM THAT PUSHES ONE TO SEEK ITS FULFILLMENT REGARDLESS OF OBSTACLES.
