In metallurgy, "as-cast" refers to the condition or state of a metal or alloy immediately after it has been solidified and cooled to room temperature without undergoing any subsequent processing or heat treatment. It describes the material's properties, structure, and characteristics as they exist in their initial, unaltered form after casting. The as-cast state can vary depending on factors such as casting method, cooling rate, and composition, and it often requires further processing or treatment to achieve desired mechanical, physical, or microstructural properties.
