Beta21S Alloy

Alloy name: Beta21S
Diagram No.: 710
Type of diagram: TTT
Chemical composition in weight %: 15Mo2.7Nb3Al0.2Si
Alloy group: Titanium-based alloys
Note: TTT diagram for Beta21S. Adapted from [6][49]. Air cooling and the subsequent rate of heating provided insufficient time for omega formation. This resulted in heterogeneous nucleation and growth of alpha at grain boundaries. However, furnace cooling from 400 C was slow enough to allow homogenous nucleation of isothermal omega, followed by heterogenous nucleation of alpha on these omega particles, yielding a much finer, more uniform distribution of alpha precipitates [6][49].
