Titanium alloys are widely used in additive manufacturing, but their complex microstructures and related micromechanical properties have not been fully explored. Here, we employ high-speed nanoindentation mapping, electron probe microanalysis, and electron backscatter diffraction to characterize as-deposited an...
There have been contradictory reports about the existence of an alpha/beta interface phase in titanium alloys over the last two decades. Recently some publications tend to Favour the notion that the interface phase is an artifact formed in the preparation of the thin foil by electropolishing. ...
Mechanical Behavior of Titanium Alloys (The Influence of Alpha/Beta Interface Phase on Tensile Properties in Ti-6Al-4V). The effects of alpha/beta interface phase on room temperature tensile properties in Ti-6Al-4V having an equiaxed primary alpha microstructure have been stu... rhodes, c. g....
With the improvement of the requirements on aerospace lightweight structural materials between 600 °C and 800 °C, traditional near alpha titanium alloys, such as IMI834 (UK), Ti-1100 (USA), Ti-60 (China) and BT36 (Russia) alloys with the highest service temperature of 600 °C, always...
Mechanical properties of the near alpha titanium alloy Ti600 with composition 6Al, 2.8Sn, 4Zr, 0.5Mo, 0.4Si, 0.1Y, bal.Ti, in wt%,were studied in different heat treatment conditions. The microstructures of the alloy were studied by LM, TEM. The resulting microstructure consists of small re...
Titanium alloys Chemical partitioning Electron probe micro analysis (EPMA) Transmission electron microscopy (TEM) Atom probe tomography (APT) 1. Introduction In typical two-phase Ti-alloys, the α phase is strengthened by solution-strengthening and in some cases also precipitation strengthening. Solution...
Most aero-engine components and structures are subjected to life critical fatigue loads during service. Near-α titanium alloy IMI 834 is one candidate
Titanium alloys have specific mechanical and physico-chemical properties, e.g. specific high strength-to-weight ratio and excellent corrosion resistance. Therefore, they are widely used in aeronautics and aerospace applications. The main areas of these are the gas turbine engines [1]. TIMETAL 834,...
