Effect of Micrononuniform Heating of Powder in Field-Assisted Sintering on Shrinkage Kinetics

  • Published:
Powder Metallurgy and Metal Ceramics Aims and scope

The paper examines the micrononuniform distribution of temperature and its influence on the rheological behavior of a copper powder with oxidized spherical particles as an effective dispersion-porous medium through which an electric current is passed. The micrononuniform distribution of temperature needs to be considered to describe the temperature dependence of the rheological behavior of effective dispersion-porous medium during resistance heating.
