Abstract

Dimensional control during liquid phase sintering is an important challenge that ideally should be assessed by a proper design of the liquid characteristics and the liquid-solid interactions. Non- infiltrating (dissolutive) liquids present higher swelling upon liquid formation and provide more homogeneous microstructures. Especially in master alloys containing oxidation-sensitive elements, the sintering atmosphere plays a major role, because the wetting properties of the liquid are affected by the presence of oxides on the liquid-solid interface. This study is focused on the analysis of the dimensional changes observed when sintering steels containing either Cu or different master alloys (Cu-based, Ni-based, or Fe-Mn-Si) under different atmospheres. The results show that the final dimensional changes are mainly affected by the capacity of the liquid to infiltrate the matrix though the pore network, and also by the presence of reducing agents either in the atmosphere - H2- or in the steel composition in the form of C added as graphite.
