Superplastic forming is an effective way to manufacture complex-shaped parts of titanium-based alloys. This paper studies the influence initial microstructure and its strain-induced evolution on superplastic deformation behavior formability a alloy. Two types Ti–Al–V–Mo alloy samples having different fraction recrystallized grains before start were studied. The behavior, including strain harden...

Introduction: Apatite is one of the minerals that is rarely utilized in U-Pb geochronology, compared to some other U-rich accessory phases. Relatively low U concentration, commonly high proportion of common Pb and low closure temperature of U-Pb system of apatite inhibit its application as geochronological tool when other minerals such as zircon are widely available. However, zircon appear to b...

Mapping of the potential distribution using a scanning electron microscope (SEM) has been reported in recent years [1,2] for semiconductors such as Si, GaAs and InP. But, there are no such studies on GaN-based devices, to our knowledge. In this study, we observed two types of GaN-based devices by SEM to see if there is a condition that the contrast matches the potential distribution of the devi...

mA. The device was deposited onto a polished glass substrate and sandwiched with a second polished piece of glass for prot~ection. At the peak in wavelength response (2 mils), an rnls output of about 25 mV was achieved. The response vanished into widebmd tape noise for a wavelength below 50 pin. A maximum rms signal-to-rms tape noise of about 66 dB wa.s observed. An applied bias field of about ...

Doubly polished thin sections, originally prepared for fluid inclusion studies, present great advantages in the study of microfossils in volcanic rocks. Better visibility and light conditions, variation in thickness of the thin sections and the possibility to combine fluid inclusion studies with microfossil studies lead to a wide range of advantages over ordinary thin sections. This includes th...

CYTOP fiber, used mainly in strain detection and refractive index characterization of liquids, can be polished for the UV light radiation. The study investigates transmission spectra fiber exposed to different intensities light, demonstrating a linear relationship. A simplified system using single wavelength, 395 nm, shows real-time performance sensor range from 1 15 mW. results reveal potentia...
