Thermal shock testing of ceramics with pulsed laser irradiation

Thermal Diffusivity of Ceramics During Neutron Irradiation

Analyzing Thermal and Mechanical Effects of Pulsed Laser Irradiation on Tissues

Thermal Relaxation Times in Biological Tissues Subjected to Pulsed Laser Irradiation

There are several expressions for calculating thermal relaxation time in tissues subjected to laser irradiation. Physically this time constant represents the time required for the temperature rise in a heated region of tissue to drop to a factor of e. In this study, we conduct combined radiation and heat conduction simulations to obtain this time constant for several different tissues, and comp...

Fracture toughness and thermal shock of tool and turbine ceramics

The behaviour of some commercial tool carbides and turbine ceramics has been investigated in regard to resistance to crack initiation, crack propagation and retained strength after thermal shock. New data are provided, particularly measurements of the fracture toughness of these materials at actual operating temperatures (up to 1200 ~ C). Many of the materials did not follow the generally accep...

Microstructural and Wear Behavior Characterization of Porous Layers Produced by Pulsed Laser Irradiation in Glass-Ceramics Substrates

In this work, wear behavior and microstructural characterization of porous layers produced in glass-ceramic substrates by pulsed laser irradiation in the nanosecond range are studied under unidirectional sliding conditions against AISI316 and corundum counterbodies. Depending on the optical configuration of the laser beam and on the working parameters, the local temperature and pressure applied...
