At a high velocity favoring thin melt- pools and a high laser power promoting elongated melt- pools, the MP become unstable, mainly due to the forma- tion of a vapor recoil pressure

& The slug temperature should be optimised in order to: allow the increase of the material desagglomeration and thus decreases the thixoforging load avoid the collapse of the slug

This study aims to improve the knowledge on the composition of the water and ethanol extractive contents of wood, knot and bark fractions from walnut branches, harvested in agroforestry

Discussion 199 Chemical characterizations of a GO electrical steel after oxidizing and nitriding show that the kinetics 200 of nitrogen adsorption and diffusion highly depends on

The dependency of the deposition probability and the dimensionless surface coverage Γ/ΓRSA on the frequency of the pitches λ, the Péclet number Pe and the favorable area fraction θ, as

Conclusions The deposition of a 50% WC–Co–Cr/50% Colmonoy 88 coating onto a SAE 4340 steel substrate by thermal spraying gives rise to a deposit with a heterogeneous microstructure and

In the case of an impact on an incompressible liquid, the peak pressure is proportional toρ V0 c2, withVcthe expansion velocity of the surface contact, see Cointe and Armand, 1987;Zhao
