Abstract
This investigation is concerned with the influence of time, temperatur e and particle radius on the increase of interparticle contacts during vacuum sintering of loosely packed spherical powders of high-speed st eels obtained by atomization with nitrogen. Values of the sintering ac tivation energy are estimated and discussed. X-ray microprobe investig ations allowed one to compile and discuss data of the distribution of metallic and non-metallic components within the sintered samples.
