Solid-state direct diffusion bonding of commercially pure Titanium (Cp-Ti) and precipitation hardening stainless steel (PHSS) has been carried out in the temperature range of 800°C to 1000°C with an interval of 50°C for 3.6 ks under 3.5 Mpa uniaxial load in (4 to 6)×10 Pa vacuum. The effects of temperatures have been investigated with reference to bond strength. The examination revealed that th...

The parenchymal lung diseases caused by metal inhalation include interstitial fibrosis, giant cell interstitial pneumonitis, chemical pneumonitis, and granulomatous disease, among others. We reported two cases of granulomatous lung disease with occupational exposure to metal dusts other than beryllium. They had worked in the battery manufacturing industry for 7 years and in an aluminum-processi...

OBJECTIVE To evaluate the remineralization of carious dentine following the restoration of an extensive lesion in a permanent molar with a high strength glass-ionomer cement (GIC). MATERIALS AND METHODS Thirteen first permanent molars, which were scheduled for extraction because of the presence of extensive caries lesions, were selected for this study. They were first restored, according to t...

Abstract Titanium alloys are widely used in the aerospace industry, yet oxygen ingress can severely degrade mechanical properties of titanium alloy components. Atom probe tomography (APT), electron microanalysis (EPMA) and nanoindentation were to characterise oxygen-rich layer on an in-service jet engine compressor disc, manufactured from TIMETAL 834. Oxygen was quantified related changes throu...

Introduction: The compositions, textures, and crystal structures of sulfides can be used to constrain oxygen fugacity, aqueous, thermal, and cooling history [e.g., 1–5]. The most abundant sulfides in extraterrestrial samples are the pyrrhotite group [(Fe,Ni,Co,Cr)1– xS], which can occur with pentlandite [(Fe,Ni,Co,Cr)9– xS8]. The pyrrhotite group sulfides are largely nonstoichiometric and have ...
