304L stainless steel syntactic foam test specimens were produced by means of injection moulding of feedstock made from pre-alloyed 304L powder, binder and additions of S60HS micro hollow glass spheres and Fillite 106 cenospheres. After de-binding and sintering the foam pore structure and matrix micro-structure were analysed. Mechanical characterisation was done using tensile and compression tests. The results of the mechanical tests are discussed in terms of the observed foam and matrix microstructures.
