Al 6063 is very famous for hot extrusion process in the manufacturing industry. I would like to study about the physical and microstructural changes happened in side during this process.
Please precise your question, because it has no sense in the manner you wrote it. You are asking if a manufacturing process is a type of failure. It's like askig if cooking is a type of fork. :)
Hot extrusion is not a type of creep failure, but it involves a process that shares some similarities with creep. Let me break it down for you:
Hot Extrusion Process:Hot extrusion is a manufacturing process where a material, often a metal or alloy like Al 6063, is forced through a die at an elevated temperature. The material is typically heated to a temperature above its recrystallization temperature but below its melting point. This allows for plastic deformation and shaping of the material.
Creep:Creep is a phenomenon associated with the slow, time-dependent deformation of materials under a constant load or stress at elevated temperatures. In creep, the material undergoes deformation over an extended period, and it is often observed in materials subjected to high temperatures and constant stress.
Relationship Between Hot Extrusion and Creep:While hot extrusion is not a type of creep failure, the process does involve plastic deformation of the material at elevated temperatures, and some aspects may resemble creep behavior. Here are a few points of comparison:
Differences:
In summary, while hot extrusion and creep both involve deformation at elevated temperatures, they serve different purposes and have distinct characteristics. Hot extrusion is a controlled manufacturing process, whereas creep is an undesired phenomenon that can lead to failure over time.
