Failure analysis and optimization of thermo-mechanical process parameters of titanium alloy (Ti–6Al–4V) fasteners for aerospace applications

Preparation of low cost TiZrAlFe alloy with ultra-high strength and favorable ductility

“…Titanium (Ti) and Ti alloys with numerous favorable properties such as low density, high specific strength, corrosion resistant, good mid-temperature properties, nonmagnetic, and so on, are important structural materials and have been widely used in national defense, aerospace, marine, motorsport et al fields [1]. Series high performance Ti alloys have been developed in recent decades such as ultra-high strength Ti alloys (the tensile strength over 1250 MPa) [2][3][4], high temperature Ti alloys [5,6] and burn-resistant Ti alloys [7,8].…”

A Method for Prediction of Ultrasonic Detectability of Interface Gap Defects on TC4 Diffusion-Bonded Joints

“…Due to the complexity of the diffusion bonding process, factors such as surface roughness of the workpiece material and contamination or improper selection of the diffusion joining process parameters will cause defects in the diffusion bonding interface. These defects, such as unbonded and interfacial microvoids, seriously reduce the mechanical properties of TC4 alloy diffusion bonding components [ 2 ], such as those of the hollow blades of aeroengines [ 3 , 4 , 5 ]. Considering the requirements for high reliability and safety in the aerospace field, reliable nondestructive testing for TC4 diffusion bonding joints is required.…”

Molecular dynamics simulations of TC4 titanium alloy with mechanical property calculations after various heat treatments

“…Due to high specific strength and excellent corrosion resistance, TC4 (Ti-6Al-4V) has found wide application in the fields of aeronautics and aerospace engineering. 1,2 Experimental studies have reported both mechanical properties and microstructure throughout its processing history. [3][4][5] Using a Gleeble thermal simulation testing machine, stress-strain curves can be measured from isothermal compression experiments.…”
