ABSTRACT
Powder metallurgy industry in Romania is steadily rising on production processes.
Producing parts with high mechanical properties and relatively low price led to the
analysis of the mechanical properties of common steel and powder metallurgy steels. In this current context, this paper was written.That is why attempts have been made on the behavior of the material at low temperatures of a classical powder metallurgy for the production of masă.Un conventional steel material containing a matrix metal of iron, (0,4 - 0.8)% C, 5 % Ni and Cu (1.5-3)% (whit diffusion alloyed powder plus carbon) shows a wide range of applications due to their static and dynamic mechanical properties and good behavior in sintering. There is generally a good behavior in the cryogenically treated materials to mechanical simple, especially traction. It can be said that there is a higher densification of these materials based on strengthening the bridges between particles.

Keywords: low temperatures, powder metallurgy, matrix metal iron, mechanical
properties.
