Change of mechanical properties in substrate during rewelding deposit

open access: yesResearch in Agricultural Engineering, 2011
A study was carried out to examine the influence of rewelding deposit of structural low carbon steel and also the changes which occur in heat-affected zone and subcritical zone during rewelding.

Numerical Verification of Tests on the Influence of the Imposed Thermal Cycles on the Structure and Properties of the S700MC Heat-Affected Zone

open access: yesMetals, 2020
The article presents the results of studies on the influence of simulated thermal cycles parameters on the structure and properties of the heat-affected zone (HAZ) of thermo-mechanically rolled S700MC steel.

Tidal Limits to Planetary Habitability [PDF]

open access: yesAstrophys.J.700:L30-L33,2009, 2009
The habitable zones of main sequence stars have traditionally been defined as the range of orbits that intercept the appropriate amount of stellar flux to permit surface water on a planet. Terrestrial exoplanets discovered to orbit M stars in these zones, which are close-in due to decreased stellar luminosity, may also undergo significant tidal heating.

Thermal impact of magmatism in subduction zones [PDF]

open access: yesEarth and Planetary Science Letters, Volume 481, 2018, Pages 73-79, 2017
Magmatism in subduction zones builds continental crust and causes most of Earth's subaerial volcanism. The production rate and composition of magmas are controlled by the thermal structure of subduction zones. A range of geochemical and heat flow evidence has recently converged to indicate that subduction zones are hotter at lithospheric depths beneath

SIMULATED HEAT AFFECTED ZONE IN WELDED STAINLESS STEEL 304L

open access: yesActa Metallurgica Slovaca, 2019
This work is a contribution study of the heat-affected zone in the real welded joint of stainless steel 304L. This zone was compared to the heat-affected zone obtained by using a thermal cycle simulation of welding.

The technology of thermal welding of the circulation piping of NPPS containing the influence of ultrasound

open access: yesNuclear Energy and Technology, 2017
The authors propose a thermal welding technology with ultrasound treatment for NPP circulation pipe-lines. This technology can significantly increase the strength of welded connections by reducing residual stresses, grain size and welded joint degassing.

Assessment of the Heat Input Effect on the Distribution of Temperature Cycles in the HAZ of S460MC Welds in MAG Welding

open access: yesMetals, 2021
Temperature cycles generated during welding have a significant effect on the changes in the HAZ of welds, regardless of whether these are changes in structure or mechanical properties; however, it is problematic to obtain temperature cycles with ...

Electron Heating in the Magnetorotational Instability: Implications for Turbulence Strength in Outer Regions of Protoplanetary Disks [PDF]

open access: yes, 2015
The magnetorotational instability (MRI) drives vigorous turbulence in a region of protoplanetary disks where the ionization fraction is sufficiently high. It has recently been shown that the electric field induced by the MRI can heat up electrons and thereby affect the ionization balance in the gas.

How does thermal pressurization of pore fluids affect 3D strike-slip earthquake dynamics and ground motions? [PDF]

open access: yesarXiv, 2022
Frictional heat during earthquake rupture raises the pressure of fault zone fluids and affects the rupture process and its seismic radiation. Here, we investigate the role of two key parameters governing thermal-pressurization of pore fluids -- hydraulic diffusivity and shear-zone half-width -- on earthquake rupture dynamics, kinematic source ...
