Thermal strengthening of low‐expansion glasses and thin‐walled glass products by ultra‐fast heat extraction [PDF]
Journal of the American Ceramic Society, 2021 Abstract Thermal strengthening remains the primary method for enhancing the practical strength of commodity glass products, however, the process is limited in terms of applicable glass thickness and coefficient of thermal expansion.

Ultrafast Heating Heat Treatment Effect on the Microstructure and Properties of Steels
Metals, 2022 The adoption of the ultrafast heating (UFH) process has gained much attention in the last few years, as the green energy and minimization of CO2 emissions are the main aspects of contemporary metal science and thermal treatment. The effect of ultrafast heating (UFH) treatment on carbon steels, non-oriented grain (NGO) electrical steels, and ferriticor ...

Evidence for ultra-fast heating in intense-laser irradiated reduced-mass targets
Physics of Plasmas, 2012 We report on an experiment irradiating individual argon droplets of 20 μm diameter with laser pulses of several Joule energy at intensities of 1019 W/cm2. K-shell emission spectroscopy was employed to determine the hot electron energy fraction and the time-integrated charge-state distribution. Spectral fitting indicates that bulk temperatures up to 160

Identification of Thermophysical Parameters Using an Artificial Immune System
Computer Assisted Methods in Engineering and Science, 2023 In this paper, the identification of thermophysical parameters using the hyperbolic twotemperature model is made. We investigate the influence of ultra-fast laser pulses on the heating of a thin metal film using this model.
