Determination of heat flux at a solid-solid intreface [PDF]
Archives of Metallurgy and Materials, 2019 Determining the boundary conditions of heat transfer in steel manufacturing is a very important issue. The heat transfer effect during contact of two solid bodies occurs in the continuous casting steel process. The temperature fields of solids taking part in heat transfer are described by the Fourier equation.

Archives of Metallurgy and Materials, 2022 Pipeline welding is an integral part of oil and gas exploration industries. Often the welded joint failures were due to lack of weld quality, improper heat treatment and even poor workmanship. Further, the use of new material in pipeline industry puts focus on a better understanding of qualifying requirements of welding for reducing the failures in ...

Archives of Metallurgy and Materials, 2021 This study investigated the effect of flux type and amounts on recovery behavior of aluminum alloy during the melting process of Al can scrap. The heat treatment was conducted to remove the coating layer on the surface of can scrap at 500°C for 30 min. The molten metal treatment of the scrap was performed at 750°C in a high-frequency induction furnace ...

Effect of powder shape on effective thermal conductivity of Cu–Ni porous coatings
Journal of Materials Research and Technology, 2018 Porous coat is a kind of increasing heat transfer coatings based on increasing surface area and bubble nucleation. Several properties of the porous coat, including effective thermal conductivity (ETC) and porosity are influential design factors in ...

A Simple Method to Calculate Time Delay Due to the Sun Gravitational Field [PDF]
Journal of Astrophysics & Aerospace Technology, 2018 The main problem is that using X-ray to determine the crystal lattices of different materials, and why they are such and not others is not yet known. For example, copper crystallizes in the FCC lattice, and iron in the bcc, which upon heating becomes fcc and this transition is used in the heat treatment of steels.

Metals, 2019 During the continuous casting (CC) of Ti-bearing steel, a steel lump can solidify in the mold (i.e., floater steel) more easily than in the Ti-free steels. This causes severe surface defects or even a breakout.
