Upward and downward unsteady-state directional solidification of a hypoeutectic Al-3wt.%Mg alloy
Solidification thermal parameters, such as growth rate, cooling rate and dendrite arm spacing ( ), have been measured in a hypoeutectic Al-Mg alloy directionally solidified under upward and downward transient heat flow conditions. The experimental setup used in this work consists of a water-cooled mould with heat being extracted from the bottom or the top, promoting upward and downward directio...
متن کاملDENDRITE FRAGMENTATION IN THE SHEARED MELT BY FATIGUE EROSION MECHANISM OF SEMISOLID Al-Si ALLOY (A.356.0
Over the last few decades, there have been many mechanisms proposed to describe the formation of the non-dendritic microstructures during Semisolid Metal (SSM) processing; including dendrite fragmentation, spherical growth, cellular growth and recalescence. Dendrite fragmentation is the most popular mechanism of all these hypotheses. It is the purpose of the present article to examine the morph...
متن کاملSolidification Behavior of Al-Mg Aluminum Alloy Using Double-Sided Arc Welding Process
As popular aluminum alloys, the 5xxx Al-Mg series, such as 5050 and 5052, etc., are widely used in applications such as automobile, pressure vessels, armor plate, and components for marine and cryogenic service. In this, as in all non-heat-treatable aluminum alloys, the weld metal zone is considered to be the weakest part of the joint and is the location of failure when the joint is loaded in t...
متن کاملInfluence of Low-Frequency Vibration and Modification on Solidification and Mechanical Properties of Al-Si Casting Alloy
One of the major aims of the modern materials foundry industry is the achievement of advanced mechanical properties of metals, especially of light non-ferrous alloys such as aluminum. Usually an alloying process is applied to obtain the required properties of aluminum alloys. However, the presented work describes an alternative approach through the application of vibration treatment, modificati...
متن کاملStudy of Dynamic Solid-Liquid Interfacial Phenomena in Hypereutectic Al-Si Alloy Using in situ HRTEM
Solid-liquid interfaces are extensively encountered in materials processing and applications. The structure and properties of these interfaces affect solidification, wetting behavior, and crystalline growth mechanisms, including epitaxial growth. The exact structural and chemical nature of these interfaces has been historically difficult to study at high resolution due to the fact that one phas...
