spinodal

Examples

• All

• Remember, and this is a spinodal curve, this is the unstable and this is the metastable region.

• From the expansion, Korteweg derived the form of the connodal and spinodal at the critical point and found that, in first approximation, they were parabolas in xy coordinates.

• A fold is as well characterized by its spinodal as it is by its connodal.

• The spinodal is the easier of the two to calculate because it follows from a local condition on the surface: a change of the sign of the curvature.

  Academic text (2002)

• Between the spinodal points, the compressibility is negative, which thermodynamics forbids.

  Academic text (2002)

• Choosing an alloy composition that can undergo a phase change or a spinodal decomposition at elevated temperatures is necessary to induce compositional segregation.

  Academic text (1996)

• (a) Diederik Korteweg's lithograph shows the spinodal (dashed curve), which bounds a saddle-shaped region.

  Academic text (2002)

• The accessory folds on the longitudinal fold originated from a tricritical point; those on the transverse folds originated from double critical points on their spinodal.

  Academic text (2002)

• After the Al reaches 1.0, the dendrites transform to two phases (ordered B2 and disordered A2 without clear phase boundaries), resulting from spinodal decomposition (Fig. 6).

• In a phase diagram, the spinodal defines the boundary where a homogeneous phase becomes unstable.
