Monitoring molten pool temperature, grain size and molten pool plasma with integrated area of the spectrum during laser additive manufacturing

Journal of Manufacturing Processes, 2021
Abstract A new approach is presented in this paper to link the integrated area of the spectral curve with the molten pool temperature, the grain size and molten pool plasma during laser additive manufacturing. A fiber laser was used to deposit the CoCrMo powder on the Q235 steel substrate.

The role of discharge plasma on molten pool dynamics in EDM

Journal of Materials Processing Technology, 2021
Abstract Each discharge in electrical discharge machining (EDM) generates a plasma with a temperature of several thousands of degrees, which not only evaporates and melts the electrode material, but also applies forces on the molten pool. To determine the role of the discharge plasma on the molten pool dynamics, this study used high-speed photography

Modelling the formation and oxidation of molten pools

Annals of Nuclear Energy, 2013
Abstract One of the main findings of the Phebus FP bundle melt down tests is that in the bundle, at the end of the test, just below the lower spacer grid a pool of molten materials forms and the rod-like geometry is completely lost. The computer simulations carried out by the mechanistic, single-rod SVECHA/QUENCH (S/Q) code revealed the formation ...
