On the Influence from Pressing Agent (PEG) on the Elastic and Plastic Mechanical Behavior of Hard Metal Powder Compacts
H Staf, M Björklund, D Fredriksson, PL Larsson - Crystals, 2023 - mdpi.com
During unloading, pressed hard metal powder compacts expand (spring back), leading to
unwarranted tensile stresses and, subsequently, crack initiation in the green body. Here, the …
