Accurate measurement of hydrogen diffusivity is vital for understanding and mitigating hydrogen embrittlement in materials.

Thermal diffusivity data for garnet schist, leucogranite and welded rhyolitic ash-flow tuff were acquired at temperatures of up to 1,260 K using laser flash analysis, which isolates the phonon ...

In this article, we discuss the laser flash diffusivity method’s working principle, applications, its advantages over other methods, and finally its limitations and research directed towards ...
