Isothermal Performance of Heat Pipes: A Review

Energies, 2022
Heat pipes transfer heat via phase transformation of the working fluid, where the working fluid will keep the temperature constant and absorb or release a large amount of latent heat during phase transformation.

A rate-independent model for the isothermal quasi-static evolution of shape-memory materials [PDF]

, 2006
This note addresses a three-dimensional model for isothermal stress-induced transformation in shape-memory polycrystalline materials. We treat the problem within the framework of the energetic formulation of rate-independent processes and investigate ...

Study on Non-Isothermal Transformation of Ti-6Al-4V in Solution Heating Stage

Metals, 2019
In order to understand the non-isothermal transformation behavior of Ti-6Al-4V titanium alloy in the continuous heating stage of solution treatment, thermal dilatometry tests with heating rates of 0.1~0.8 °C/s were designed.

Kinetics of isothermal and non-isothermal precipitation in an Al-6at%Si alloy [PDF]

, 1998
A novel theory which describes the progress of a thermally activated reaction under isothermal and linear heating conditions is presented. It incorporates nucleation, growth and impingement and takes account of temperaturedependent solubility.
