      abstract     = {This work investigates the effects of the sintering
                      conditions on the morphology and mechanical performance of
                      stainless steel (SS) hollow fibres. It was found that the
                      morphology of the green hollow fibre to a large extent
                      predetermines the final morphology of the sintered hollow
                      fibre. There is a set of conditions which produce hollow
                      fibres with high mechanical strength over 1000 MPa such as
                      using small SS particles (6 and 10 μm), PEI as the
                      polymeric binder and minimal amounts of the viscosity
                      modifier PVP (preferably close to 0 $wt\%),$ particle
                      loadings higher than 50 $wt\%,$ and sintering temperatures
                      between 1050 and 1100 °C. The ductility of the hollow
                      fibres was not greatly affected by these parameters as
                      flexural strain variations were very small, though sintering
                      in argon resulted in the formation of a few larger pores
                      which tended to propagate cracks, leading to lower flexural
                      strain. The sintering process in inert gases resulted in
                      mass transfer of residual carbon from the binder to the SS
                      particle, leading to regions of rich and lean chromium
                      carbides, though mechanical effects of these inclusions were
                      not significant. Finally, the morphology played a major role
                      as SS hollow fibres containing a higher volume of
                      sponge-like region were mechanically stronger than the
                      analogous fibres dominated by finger-like and macroporous
                      regions.},
