Characterization of interface irradiation damage in Ti-clad V-4Cr-4Ti composite material

Environmental effects on irradiation creep behavior of highly purified V-4Cr-4Ti alloys (NIFS-Heats) irradiated by neutrons

Drilling Damage in Composite Material

The characteristics of carbon fibre reinforced laminates have widened their use from aerospace to domestic appliances, and new possibilities for their usage emerge almost daily. In many of the possible applications, the laminates need to be drilled for assembly purposes. It is known that a drilling process that reduces the drill thrust force can decrease the risk of delamination. In this work, ...

Effect of Chromium Content on Mechanical Properties of V-xCr-4Ti-0.15Y Alloys

A combined effect of purification and yttrium (Y) addition was investigated to improve impact properties of high-chromium V-xCr-4Ti alloys. Tensile tests and Charpy impact tests were carried out by using miniaturized specimens. V-10Cr-4Ti-0.15Y alloy had ultimate tensile stress (UTS) at 700 oC and yield stress (YS) approximately equal to and higher than those of V-4Cr-4Ti alloy, respectively. V...

Interface Characterization of Plasma Sprayed Hydroxyapatite Coat on Ti 6Al 4V

Hydroxyapatite (HA), a material proven to be biocompatible within the human body, has been produced to a high level of purity. This material has been applied as a coating on Ti-6Al-4V alloy by using the air plasma spraying technique. The coat was characterizted with SEM, XRD, FTIR and Raman spectroscopy methods to consist of a mixture of calcium phosphates including HA mainly and traces of tric...

Microstructural study of Ti/3YSZ interface in NI 105/Ni/Nb/Ti/3YSZ diffusion bonding

In this research, the diffusion bonding of the stabilized zirconia ceramic and Nimonic 105 superalloy using Ti/Nb/Ni multi-interlayer was carried out. Joint was performed using the plasma spark technique in a vacuum atmosphere and at different temperatures and times. The microstructure of the different joint zones was studied using optical and FESEM microscopes equipped with an EDS analyzer. Th...
