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.

Twinning and Sequential Kinking in Lamellar Ti-6Al-4V Alloy

SSRN Electronic Journal, 2019
Abstract Fully lamellar Ti-6Al-4V alloys comprise body-centered cubic (BCC) β lamellae in large-sized, hexagonal close-packed (HCP) α colonies and exhibit outstanding toughness. Although α/β interfaces are considered to play a key role in plastic deformation connected to the toughness, the interface effects have not been revealed so far. In this work,

On the young's moduli of Ti6Al4V alloys

Scripta Metallurgica et Materialia, 1993
In this paper, the authors will present an iterative approach to Young's modulus of multi-phase composites developed by Fan et al. The iterative approach will then be applied to Ti-6Al-4V alloys to predict their effective Young's moduli. It is hoped that the theoretical predictions will offer a quantitative explanation to the peculiar shape of the E ...

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 ...

Deformation of Ti-6Al-4V Alloy with Carbon

Solid State Phenomena, 2011
This paper presents the results from investigations on the effect of temperature and strain rate on the shape of the stress-strain curves, the peak flow stress and microstructure of Ti-6Al-4V alloy with carbon (0.7–0.8 wt%) that were axisymmetrically compressed on a thermo-mechanical simulator Gleeble 3800.

Corrosion behavior of cast Ti‐6Al‐4V alloyed with Cu

Journal of Biomedical Materials Research Part B: Applied Biomaterials, 2005
AbstractIt has recently been found that alloying with copper improved the inherently poor grindability and wear resistance of titanium. This study characterized the corrosion behavior of cast Ti‐6Al‐4V alloyed with copper. Alloys (0.9 or 3.5 mass % Cu) were cast with the use of a magnesia‐based investment in a centrifugal casting machine.

Fretting Fatigue of Ti-6Al-4V Alloy

1982
A study of the fretting fatigue process in sheet specimens of Ti-6Al-4V alloy has been carried out. In the fretting experiments two fretting pads, also of Ti-6Al-4V, were clamped to the fatigue specimen by a calibrated proving ring. In the experiments the fretting pressure and the fatigue stress amplitude were varied.

Thermo Physical Property Measurement of Ti-6Al-4V Alloy and Ti-6Al-4V/Nano SiCp Composites

International Review of Mechanical Engineering (IREME), 2014
The intention of a thermal-control structure is to sustain all of a spacecraft's components within the permissible temperature limits for all working modes of the vehicle in all of the thermal environments it may be exposed. Metal-matrix composites can endure the tremendous conditions often stumble upon in space environment. The metal-matrix composites

High-temperature mechanical behavior of Ti-6Al-4V alloy and TiC p /Ti-6Al-4V composite

Metallurgical and Materials Transactions A, 1999
Mechanical behaviors at 538 °C, including tensile and creep properties, were investigated for both the Ti-6Al-4V alloy and the Ti-6Al-4V composite reinforced with 10 wt pct TiC particulates fabricated by cold and hot isostatic pressing (CHIP). It was shown that the yield strength (YS) and ultimate tensile strength (UTS) of the composite were greater ...

Diffusion bonding of SiC/Ti–6Al–4V composite to Ti–6Al–4V alloy and fracture behaviour of joint

Materials Science and Technology, 1993
AbstractContinuous SiC fibre reinforced Ti–6Al–4V composites were diffusion bonded to Ti–6Al–4V alloy. Bondability and the fracture mechanism of the joint were investigated. The joint strength increased with bonding time, and was a maximum at 850 MN m−2 for Vf=30% composite and 650 MN m−2 for Vf=45% composite. The bonding was completed sooner for Vf=30%
