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

open access: yesMetals, 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.

Determination of the transformation exponent s from experiments at constant heating rate

open access: yes, 1997
The transformation exponent s is a characteristic of the mechanism of a reaction and contains information on nucleation rate and type of growth; it corresponds to the Avrami parameter n in isothermal experiments.

Physically-Based Modeling and Characterization of Hot Flow Behavior in an Interphase-Precipitated Ti-Mo Microalloyed Steel

open access: yesMetals, 2018
In this contribution, a series of hot compression tests was conducted on a typical interphase-precipitated Ti-Mo steel at relatively higher strain rates of 0.1~10 s−1 and temperatures of 900~1150 °C using a Gleeble-2000 thermo-mechanical simulator.

Crystallization Behavior of a Ferri-Silicate α-Waste Glass

open access: yes, 1985
The crystallization behavior of a ferri-silicate α-waste glass was studied by means of several experimental techniques. The main crystal phase showed a plate-like morphology and was identified as a monoclinic pyroxene.
