They have used anisothermal and isothermal annealing
methods to do it.
The in situ experiments for this study were carried out in forming gas, and the annealing procedure consisted of two steps: (a) isothermal annealing
at 450[degrees]C and (b) ramped annealing from 450[degrees]C to 750[degrees]C at a rate of 40[degrees]C/min.
 (and for quenching followed by isothermal annealing
at 60[degrees]C Li et al.
Following long-term isothermal annealing
leads to achievement of equilibrium chemical compositions of the phases.
Clause 5 Regarding Pre-Machining Heat Treatment May Be Read As- Suitable Isothermal Annealing
Based On Composition And Dimensions Of Forging Block May Be Decided By Manufacturer So As To Relieve Residual Stress As A Pre Machining Treatment Of Forged Blanks.
In its production of cast components, AEP uses a significant amount of nitrogen for isothermal annealing
and ferritic nitrocarburizing.
For this research, the long-term isothermal annealing
at room temperature was used.
Among the topics there are the comparative Mossbauer analysis of the superfine structure of Hadfield steel under different kinds of severe deformation, the isochronal and isothermal annealing
of wrought aluminum alloy, the quantitative analysis of fiber fracture in powder injection molded metal composites, the characterization and properties of copper-silica sand nanoparticle composites, modeling three-dimensional moving heat sources in a semi-infinite medium and applications to submerged arc welding, and self-diffusion in nano zinc sulphide.
Recently investigated spheroidization processes can be divided into four groups: isothermal annealing
at a temperature slightly below [A.sub.1], thermal cycling near [A.sub.1], isothermal annealing
with the aid of prior cold work and finally, hot deformation before, during or after the transformation of austenite to pearlite (Kamyabi-Gol, 2010).
The condensates were investigated in the initial condition and after heat treatment, isothermal annealing
in vacuum at T = 650[degrees]C, for 2 h.
For example, the Universal Instruments Consortium observed that, upon isothermal annealing
at 150[degrees]C, some SnAgCu (SAC) solder joints showed increased void formation at the interface between the Cu-Sn intermetallic layer and the copper plating.
The part required subsequent isothermal annealing
and shot blasting.
