Atomic Force Microscopy: A powerful tool to study the radial gradients in mechanical properties of hard-drawn pearlitic steel wire

摘要

In this investigation. Atomic Force Microscopy has been applied to study the nano-scale lamellar microstructure of heavily deformed (ε =4) pearlitic steel wire used in automotive applications. In combination with high-resolution SEM and mechanical testing, the influence of the process parameters on radial gradients in the wire properties has been characterized.
