The Alpha–Beta Phase Transformation interface is a specialized interface that is used to model phase transformations in α–β titanium alloys, such as Ti–6Al–4V. These alloys find uses in welding as well as additive manufacturing. In these applications, the material typically undergoes both heating and cooling, and depending on the rates at which this happens, different fractions of beta phase and alpha phases can form. The Alpha–Beta Phase Transformation interface automatically creates phase nodes and phase transformation nodes. In addition, transformation conditions are imposed the phase transformation nodes to, for example, restrict phase transformations to cooling or heating. The Alpha–Beta Phase Transformation interface lets you generate a compound material whose properties are phase-composition-dependent. This material can be used by other physics interfaces, such as Solid Mechanics and Heat Transfer in Solids.
