Nondestructive evaluation is used widely in many engineering and industrial areas to detect defects or flaws such as cracks inside parts or structures during manufacturing or for products that need to be inspected while in service. The commonly-used standard statistical model for such data is a simple empirical linear regression between the (possibly transformed) signal response variables and t...

C250 steel, renowned for its remarkable strength and toughness, is extensively utilized in the aerospace industry manufacturing critical components. This research investigates microstructure properties of forgings produced through different heat treatment temperatures, aging durations, thermal cycling intervals. The results demonstrate that samples were compressed at 1050 °C followed by air-coo...
