A main challenge in open conduit volcanoes is to detect and interpret the ultra-small strain (<10 –6 ) associated with minor but critical eruptions such as lava fountains. Two years after flank eruption of December 2018, Etna generated a violent spectacular eruptive sequence There were 23 episodes from 13, 2020 March 31, 2021, 17 which brief period 16 February 31 an intensified occurrenc...

In this study, an Co/Fe coated porcelain using a cobalt and ferrous sulfate was sintered at 1,250 °C. The specimens were investigated by HR-XRD, FE-SEM (EDS), Dilatometer, UV-vis spectrophotometer. surface of the uniformly fused with pigment, white ware celadon body densely to certain thickness from surface. Other new compounds produced chemical reaction cobalt/ferrous during sintering process....

The spring steel for automotive stabilizer bars has a great responsibility in that its quality directly affects the stability, safety, and comfort of vehicle operation. isothermal thermal compression behavior novel lean Si was used to manufacture an anti-roll bar investigated with DIL805A/D quenching dilatometer this research. A hyperbolic sine type constitutive model established, hot processin...

Abstract Short-term heat treatments of steels are used for tools and cutlery but also the surface treatment a variety other workpieces. If corrosion resistance is required, martensitic stainless like AISI 420L or 420MoV typically used. The influence short-term on different metastable states steel was examined reported in this article. Starting from defined microstructural state, investigated ex...

High‐energy synchrotron X‐ray small‐angle scattering (SAXS) is used to study the precipitate development during hot rolling and cooling of a commercial Ti–Nb micro‐alloyed, high‐strength, low‐alloy (HSLA) steel. To precipitation conditions, Gleeble dilatometer trials are made. Samples then studied at room temperature using SAXS in conjunction with transmission electron microscopy (TEM). TEM det...

rndetermination of rock mass deformation modulus is very important in different projects, especially in civil and mining engineering works. in-situ measurements such as dilatometer, plate load and flat jack methods may be applied to determine the deformation modulus. however, these methods are very expensive and time- consuming. analytical methods are very useful approaches which can also be us...

Abstract The role of titanium and vanadium carbonitrides (Ti,V)(C,N) the MX series on austenite-to-ferrite transformation in microalloyed steels their potential acting as pre-nuclei for intragranular ferrite nucleation is examined experimentally by computational simulation. Thermal treatments single-hit compression tests are performed a dilatometer Gleeble® 3800 thermomechanical simulator to in...
