To further previous works on grain refinement in ferritic stainless steel (FSS) welds via elemental powder addition, microstructure evolution and mechanical properties in non-metallic carbide treated FSS weld is discussed. Silicon carbide (SiC) powder preplaced on medium chromium FSS bevelled joint was fusion melted using tungsten inert gas (TIG) torch at different combination of process parameters. The incorporation of the powder in the weld pool constricted the weld geometry in addition to grain modification from columnar to equiaxed grain structure. Whilst significant improvement was obtained in hardness characteristics in powder treated welds, those of ductility and tensile strength were marginal. The study also established that welds mechanical properties are controlled by a combination of phenomena such as phase fraction and grain morphology.

An experimental study of the microstructural and texture evolution attending recrystallization of Nb-Ti stabilized ferritic stainless steel is presented. Two specimens with different Nb-Ti compositions, TCS345 and B4003, have been selected for comparison. The result shows that, after annealing at 750 °C for 5min, the major orientation in the TCS345 specimen locates at {111}, microstructures presents an equiaxed grain morphology, whereas the texture in the B4003 is not typical recrystallization texture and remains weak, indicating recrystallization occur preferentially to the TCS345 sheet. And after continuous annealing at 850°C for 5 min, the texture in TCS345 remains stronger than in the B4003, indicating that the additional amount of Nb-Ti acts to significantly hinder the recrystallization process.
