I keep coming across this term. Is it just referring to the alloy after it has gone through the casting process?
Virtuous said:I am pretty sure its without heat treatment.
Astronuc said:In my experience, 'as-cast' refers to a cast product without further processing, i.e. no mechanical and/or heat treatment.
I've seen surface finish requirements on cast products where the surface is referring to 'as-cast', i.e., no machining, grinding, linishing, polishing, sanding... as brewnog mentioned.
'As-cast' refers to the state of a material or substance as it is directly produced and solidified from its molten form during the casting process. It is the initial form of the material before any further processing or manipulation.
The 'as-cast' state can significantly affect the properties of a material, as it is directly influenced by the cooling rate during the casting process. This can result in variations in the microstructure and mechanical properties of the material.
Yes, the 'as-cast' state can be modified or improved through various post-processing techniques such as heat treatment, mechanical working, and surface treatments. These processes can alter the microstructure and properties of the material to meet specific requirements.
The 'as-cast' state is commonly used in industries such as automotive, aerospace, and construction, where complex and large components are produced through casting processes. It is also used in the production of metal alloys, plastics, and ceramics.
The 'as-cast' state is evaluated through various techniques such as microstructural analysis, mechanical testing, and surface characterization. These methods help to assess the properties and performance of the material in its original state and compare it to the desired properties.
