WebThe tentative solvus curve in the Nb-rich region of the Al--Nb phase diagram was determined. Metallographic and x-ray studies of anamealed Al-Nb alloys containing 28.5 to 42.0 at.% Al indicate that the homogeneity range of the intermediate phase Nb/sub 2/Al is rather narrow, from 28.5 to 36 at.% Al. (D.L.C.) WebApr 5, 2024 · As the volume ratios of OA/OAm increase, different products such as CsBr, Cs 4 PbBr 6 (0D), white δ-CsPbBr 3 (1D), γ-CsPbBr 3 (3D) associated with PbBr 2 sheets, and γ-CsPbBr 3 are obtained in order. 1D δ-CsPbBr 3 can be transformed into 2D CsPb 2 Br 5 through CsBr stripping in water. The phase diagram established in this work is …
