Description

The powder metallurgy (PM) industry is a high volume, low cost margin market. Therefore, it is essential that flaws are detected as early as possible in the manufacturing process. Previous NDE research has been directed towards finished products and has employed traditional methods such as ultrasound and eddy-current based testing techniques. However, the goal of this work is to develop a NDE method for green-state PM parts, the state prior to sintering. The material in these parts consist of large loosely packed grains of compressed powder, which are often ferrous, making most traditional methods unsatisfactory.
