BIFILMS AND HOT TEARING OF Al-Si ALLOYS
(Shape Cutlng: 6th lntenudlmud Symposiam, Springer Link, 2016-01-01)
Hot tearing is one of the most interesting defects that can be found during casting of aluminium alloys. The definition of this defects has some uncertainties such as “it does not always appear under apparently identical ...
STUDY GAS FLOW HEATING IN MICRO-NOZZLE THROUGH WALLS INSTEAD OF PREHEATING
Previously, Preheating has been established in micro-nozzles to increase the specific impulse of thrusters and increase thrust level. However, heating may cause higher viscous losses in micro-nozzles working at low Reynolds ...
Effect of Cooling Intensity and Position on Solidification in Semi-Continuous Casting of Copper
(Open Journal of Fluid Dynamics, 2016-09-13)
Cooling heat flux effect in both primary and secondary cooling zone has been studied in semi-continuous casting of copper billet. Sufficient cooling is essential to reduce casting defects and to get high productivity, ...
