Surface microcracks of EAA
Problembeschreibung
Microcracks of 0.05-0.2mm appear on the surface of EAA products, affecting appearance and strength
Ursachenanalyse
The internal stress of EAA products is too large, exceeding the yield stress of the material; environmental stress cracking; stress concentration in product design
Lösung
1) Annealing treatment to release internal stress; 2) Design the product to avoid sharp corners and stress concentration; 3) Select high molecular weight EAA to improve crack resistance
Wichtigste Erkenntnis
Microcracks are caused by excessive internal stress; annealing and crack-resistant design are the key
