The linear shrinkage of nanometric iron powders consolidated at 1.5 GP
a was studied using different atmospheres. The variations in shrinkage
were analysed for the initial stage of sintering during isothermal ex
periments. From sintering data analysis, it was possible to calculate
the activation energy of the responsible mass transport process in the
initial stage.
