Abstract:
The most decisive microstructural parameter of sintered steels is the porosity which determines all mechanical properties. The porosity can be nearly completely abolished
by hot-isostatic pressing or powder forging in order to improve the material behaviour. But such techniques are often not applied in practice because of economic reasons.
However, mechanical surface treatments give the chance to reduce the porosity at the surface significantly and increase the fatigue properties by densifying.
I
n this paper the influence of shot peening, as surface densifying treatment, on the fatigue behaviour of the alloys Fe-1.5% Cu and Fe-2% Cu-2.5% Ni, in the densities 7.1 and
7.4 g/cm(3), as sintered and carbonitrided, having broad application in automotive industry, is investigated under constant and variable amplitude loading. In particular
the role of Ni as alloying element is discussed.
