Microindentation study of Ti–6Al–4V alloy

Materials & Design, 2011
Abstract In order to study the micromechanical behavior of Ti–6Al–4V alloy, microindentation experiments were performed with five different maximum loads of 100, 150, 200, 250 and 300 mN, and with three loading speeds of 6.4560, 7.7473 and 9.6841 mN/s respectively.

Superplastic deformation of Ti-6Al-4V alloy

Metallurgical Transactions A, 1977
The alloy Ti-6-Al-4V deforms superplastically in the temperature range 750 to 950° The most important factor which is responsible for superplastic behavior was found to be the very fine grain size. Strain rate has no direct effect on superplasticity, however when the strain rate is very low (approximately 2 × 10 s), prolonged exposure to high ...

Microstructural evolution and stress state related to mechanical properties of electron beam melted Ti-6Al-4V alloy modified by laser shock peening

, 2020
This work characterizes microstructural evolutions of electron beam melted (EBM) Ti-6Al-4V alloy modified via laser shock peening (LSP). The depth stress distribution and tensile properties of EBM Ti-6Al-4V alloy were measured before and after LSP.

Constitutive equation for superplastic Ti–6Al–4V alloy

Materials & Design, 2008
Abstract Superplasticity is the capability of some materials to exhibit large plastic deformations prior to failure. Structural superplasticity is observed in fine-grained alloys (the average grain size does not exceed 10 μm) under proper conditions of: • high temperature (greater than about one-half the absolute melting point); • a controlled

Mechanical properties of cast Ti‐6Al‐4V‐XCu alloys

Journal of Oral Rehabilitation, 2004
summary  The mechanical properties of Ti‐6Al‐4V‐XCu (1, 4 and 10 wt% Cu) alloys were examined. The castings for each alloy were made in a centrifugal titanium casting machine. Two shapes of specimens were used: a dumbbell (20 mm gauge length × 2·8 mm diameter) for mechanical property studies, and a flat slab (2 mm × 10 mm × 10 mm) for metallography ...

Grindability of Cast Ti‐6Al‐4V Alloyed with Copper

Journal of Prosthodontics, 2009
Abstract Purpose: This study investigated the grindability of cast Ti‐6Al‐4V alloyed with copper. Materials and Methods: The metals tested were commercially pure titanium (CP Ti), Ti‐6Al‐4V, experimental Ti‐6Al‐4V‐Cu (1, 4, and 10 wt% Cu), and Co‐Cr alloy. Each metal was cast into five blocks (3.0 × 8.0 × 30.0 mm3).

Laser glazing of Ti-6Al-4V alloy

ICALEO '89: Proceedings of the Materials Processing Conference, 1989
The present investigation is undertaken to assert the possibility of improving the surface properties of Ti-6Al-4V alloy through laser glazing, that is by generating a thin layer of refined microstructure on the surface. The studies have been carried out on a 5 KW CW CO2 laser and a 5 axis computer controlled work station.
