Material transport mechanisms and activation energy in nanometric Fe powders based on sintering experiments Article uri icon

abstract

  • The linear shrinkage of nanometric iron powders consolidated at 1.5 GPa was studied using different atmospheres. The variations in shrinkage were analysed for the initial stage of sintering during isothermal experiments. From sintering data analysis, it was possible to calculate the activation energy of the responsible mass transport process in the initial stage. © 1995.
