Erik Carton

Apart from the formability and freedom in alloying the use of metal powder has a lot of disadvantanges:

The need to sinter (high temperature, high energy process in a controlled atmosphere) increases the costs, while the starting material is already quite expensive (atomization process). Shrinkage during sintering results in dimensional differences (shape and inaccuracy) and potentially to internal stress in the product. The shaping process (green manufacturing) requires quite expensive molds that are only economical for very large production numbers.

Thank you Erik Carton for the feedback. However, is it by using the modelling material model to predict its mechanical properties will need to overcome the large errors occur in the comparison with the experimental data?
