RELEASING THE WELDED PARTS THROUGH THERMAL TREATMENTS [PDF]

open access: yesFiabilitate şi Durabilitate, 2023
Heat treatments before welding are applied to steels in order to bring them to the state in which they can best support the welding operation (normalization, stress relief or recrystallization).

Thermal Analysis of Si/GaAs Bonding Wafers and Mitigation Strategies of the Bonding Stresses

open access: yesAdvances in Materials Science and Engineering, 2017
In order to effectively reduce the thermal stresses of Si/GaAs bonding wafers during their annealing process, first of all, based on E. Suhir’s bimaterial thermal stress theory, the thermal stresses in the wafer bonding interfaces are analyzed and the ...

Quenching induced residue stress in M50 steel ring: a FEM simulation

open access: yesJournal of Materials Research and Technology, 2023
A finite element method (FEM) combined with subroutines was established and used for tracing the evolution of stresses in M50 steel in quenching. The constitutive relation and thermal physical properties of M50 steel were tested and integrated into the ...

The problem of creating an automated system to control growth of single crystal sapphires from melt as a problem of control and monitoring of a complex nonlinear and dynamic system [PDF]

open access: yesE3S Web of Conferences, 2019
The paper mentions some problems of automated control system development for growth of large (150 kg and above) single crystal sapphires. We obtain an analytical equation for the temperature distribution and thermal stresses along the crystal axis during
