Table 1 Comparison of Characteristics of a variety of titanium alloys

Types of alloys	Rel/MPa	Rm/MPa	A/%	Features
Alpha Alloys	200~500	250-550	15~25	99% pure titanium, performance changes along with oxygen content
Near-alpha Alloys	850~1000	950~1100	12~15	Have certain creep resistance, a small amount of β (stabilization of iron impurities) can be refined grains; welding performance is good, can be forged.
Alpha and beta Alloys	900~1200	1000~1300	10~15	Low temperature in the range of 400 ℃ all have good performance; It is easy to change the grain structure through the thermo-mechanical treatment.
Beta Alloys	1100~1300	1250~1400	6~10	Can be aging heat treatment; Forming properties before aging is excellent.

◆ The “A” in the table represents Plasticity.
The “Rel/Rm” in the table represents Yield ratio.

* Yield ratio is low, it indicates that the plasticity of material is preferably; Yield ratio is high, it indicates that the deformation resistance of materials is strong, and is not easy to occur plastic deformation.
