nitrogen and carbon compounds ε computer simulation of electron diffraction pattern analysis


Between the speed,[link widoczny dla zalogowanych], that O. 5 <R <0.76cm / h range, the resulting shape of the transition is a complex organization. In summary, through changes in growth rate can control the Bi / MnBi crystal morphology as well MnBi phase is ferromagnetic, in order to obtain strong anisotropy of the composite material, must make the rules MnBi bent along parallel and distributed axial , apparently. To obtain such an organization, that is, Bi / MnBi in-situ composites, in this experimental conditions, G a] 05K/cm, its growth rate should not be too low to greater than 0.76cm / h is appropriate. 3 Conclusions (1) Bi / MnBi eutectic MnBi phase in the leaf sheet is essentially a crystal, in the R ≤ 0.50era / h when you can get this organization} R ≥ 0.76cm / h time, MnBi phase into a polygonal cross-section of the prism-like crystals. (2) MnBi crystal phase transition from the leaf into the polygon prism sheet-like crystals with the solidification rate is a gradual process of change. (3) organizations to obtain regulatory La in Bi / MnBi eutectic composite solidification rate should not be too low, (4) in the unidirectional solidification of the initial dip area too, MnBi phase crystals grow into leaf sheet, and the length of the region and the size of the solidification rate, the smaller the solidification rate, the longer the region, does not appear until the prismatic crystals.
