Abstract
On the basis of experimental data for the sintering of nickel powder u nder a regime of alternate isothermal and non-isothermal periods, it i s shown that a mathematical model of pore volume decrease is capable o f describing the process over the temperature range 550-900 degrees C. It appears that in all cases both the time and temperature dependence of pore volume shrinkage are determined by parameter-constants which depend on the method of production of the initial powder.
