Microstructural Evolution during Sintering and Fracture Behavior of Iron-Copper-Carbon Compacts Made with Elemental Powders

What is it about?

Ferrous metal powders are often alloyed using elemental particulate additives. These additives alloy by diffusion during sintering and provide property benefits over what the base powder alone would have. Copper is an element used frequently to increase strength in iron-based alloy systems. The effects of alloying with copper and the property improvements are discussed, with the focus on the development of the microstructure and changes to the fracture surfaces produced from testing.
