A bimodal structured commercial pure (CP) titanium consisted of coarse grained α Ti plates with an average thickness of 1.60μm and ultrafine structured β transformed domains was fabricated by high energy mechanical milling of a TiH 2 powder, in-situ dehydrogenation of TiH 2 and powder ...
The tensile strengths of the duplex microstructural BT25Y titanium alloys with different contents of Al, W, and Mo have been measured at room and high temperatures. According to Kolachev' formula, the equivalent formulae of yield strength and ultimate tensile strength were derived with the ...
Ultra-fine grained titanium alloys (grain size 0.3–0.5 μm) are obtained through a process in which 0.5 mass% of protium is absorbed and the protium desorption temperature is lowered from 973 to 873 K. The β-phase percentage in the α-phase matrix tends to increase as a result of this...
Strength and Toughness of a Metastable Beta-Titanium Alloy as Influenced by Strain Rate Variations It is shown that as the strain rate increases the yield strength, ultimate tensile strength, and ductility also increase. As a result of the decrease ... Chait,YR Fiorini,RT Horstman,... - 《...
In this technical paper, the microstructure, hardness, tensile deformation and final fracture behaviour of an emerging titanium alloy for performance-critical applications are presented and discussed. Both longitudinal and transverse test specimens were prepared from the as-provided s...
If the material is unloaded at this point, the stress-strain curve will be parallel to that portion of the curve between the origin and the yield point. If it is re-loaded it will follow the unloading curve up again to the ultimate strength, which has become the new yield strength. ...

The tensile strength, yield strength and work-hardening rate reach a minimum value at the thickness of 30 µm because the main deformation microstructures including dislocations, twins and deformation induced face-centered cubic titanium (fcc-Ti) are different in different foils. The density of ...
In this paper, the acoustic impedance property has been employed to predict the ultimate tensile strength (UTS) and yield strength (YS) of pure metals and alloys. Novel algorithms were developed, depending on three experimentally measured parameters, and
