Book Description
Fossil fuels will eventually be replaced by renewables. Currently, the most feasible and efficient way of utilising renewable energy is to convert it to electricity. In response to this change, fossil energy-based pyrometallurgical processes will inevitably shift to electricity driven processes. This chapter considers the feasibility of direct conversion of mineral to metal powder using a new electrochemical method, the FFC Cambridge process (Fray, Farthing and Chen). The discussion will be on the background of electrometallurgy and powder metallurgy, the principles of the new process and its application for metal powder production, and the direct route from oxide precursors to alloyed powders.

Book Description
This chapter introduces the novel method of mechanochemical synthesis as an effective method for synthesizing metal powders in the nanocrystalline state. After introducing the basic principles of the process, process parameters that affect the constitution and microstructure of the processed powders are discussed. The mechanisms of alloying and grain refinement are also described. Methods for achieving the smallest possible grain size are highlighted. Current problems associated with the consolidation of powders to bulk shape are described. The ubiquitous problem of powder contamination during milling and solutions to eliminate or minimize this are also emphasized.

Book Description
We have studied the shock wave consolidation of copper, 4330 steel and aluminum+6% silicon powders. We measured the Hugoniots of the unsintered powders using piezoresistive pressure sensors as well as impedance matching techniques and found that they can be well described by available models for pore collapse. An elementary model for the surface heating was developed based on the flux of energy at the interfaces between powder particles during compaction. This model was found to agree quantitatively with observations of localized microstructural modifications in recovered specimens. We found that most of the energy of the compaction shock is deposited at the particle interfaces and that powder particle morphology and specific surface area are important variables. Localized thermal modifications can be either solid state transformations or surface melting and rapid cooling can produce metastable structures. Knowledge of the shock history is essential to the interpretation and control of the consolidated microstructure. We have produced and tested consolidated aluminum+6% silicon that has tensile properties comparable to those of wrought material.
