What is beta phase material?
What is beta phase material?
The alpha and beta phases are phases that represent a solid solution of elements A and B. The alpha phase will have a crystal structure like pure A and will contain some B substituting in the crystal lattice. Likewise, beta phase will have an element B crystal structure with A substituting for some B atoms.
What is beta phase in metallurgy?
The beta phase can be introduced to TiAl alloys by the addition of β stabilizing elements such as Cr, Nb, W, and Mo. The β phase has BCC lattice structure and is softer than α2 and γ phases in TiAl alloys at elevated temperatures and hence is thought to have a detrimental effect on creep strength [93].
What is beta phase in titanium?
Properties. Generally, beta-phase titanium is the more ductile phase and alpha-phase is stronger yet less ductile, due to the larger number of slip planes in the bcc structure of the beta-phase in comparison to the hcp alpha-phase. Alpha-beta-phase titanium has a mechanical property which is in between both.
What are two alpha phase stabilizing elements for titanium?
2.2 General Classification
| Type/Material Property | α and near α | Near β and β |
|---|---|---|
| α stabilizing elements | Al, Sn, Ga, Zr, C, O, N | |
| β stabilizing elements | V, Mo, Nb, Ta, Cr | |
| Typical materials | Commercially pure Ti | Ti––3Al––8V–6Cr–4Mo–4Zr |
| Ti–5Al–2.5Sn | Ti–4.5Al–3V–2Mo–2Fe |
What are the Alpha and beta phases of titanium?
In titanium processing: Alpha and beta phases The atoms of pure titanium align in the solid state in either a hexagonal close-packed crystalline structure, called the alpha (α) phase, or a body-centred cubic structure, called the beta (β) phase. uranium crystals.
What does beta phase mean in software development?
Beta phase may refer to: 1 the second phase in a software release life cycle: see Software release life cycle 2 Beta 3 the second phase of pharmacokinetics: see Pharmacokinetics 4 Stages of Pharmacokinetic Processes More
What’s the difference between alpha and beta phases?
A is the silver-rich phase called alpha, B is the copper-rich phase called beta, and both are FCC with different crystal sizes and chemical makeups. The area marked C is where the solid exists as both phases, containing both alpha and beta grains.
When does the Alpha and beta phases occur in uranium?
…known as the alpha (α), beta (β), and gamma (γ) phases. Transformation from the alpha to the beta phase occurs at 668° C (1,234° F) and from the beta to the gamma phase at 775° C (1,427° F). Gamma uranium has a body-centred cubic (bcc) crystal structure, while beta uranium…
