Green compact density
Weband green strength enhancement allows the P/M part fabricator to design the compact properly and to reduce the likelihood of green cracks. [11,12] Typically, higher green densities lead to greater green expansion. For a complex-shaped part, there can be large density variations between different sections of the compact.
