Dynamic studies on the sintering of compacted metal powders using an environmental scanning electron microscope

Iyengar, Srinivasan N. LU (2009) 2009 International Conference on Powder Metallurgy and Particulate Materials, PowderMet 2009 p.1-10
Abstract

The sintering of pre-pressed powders of iron, copper and nickel has been studied in situ using an Environmental scanning electron microscope. The small samples were slowly heated to sintering temperatures in a reducing atmosphere. Continuous monitoring of the fracture surface of the sample revealed the initial formation of inter-particle bonds at relatively low temperatures for fine particles. The effect of particle size on sintering has been studied and the results indicate that finer particles (<10μm) could sinter at temperatures 100 to 200° lower than those for coarser particles (>50 to 100 μm). This type of information obtained in the laboratory could be useful in fine tuning process parameters for a given particle mix.
