Friction stir processing (FSP) of cast and mill annealed Ti-6Al-4V was studied to determine whether this thermomechanical processing technique is feasible for local microstructural modification to improve fatigue properties for aerospace engine appli

Friction stir processing (FSP) is a novel metal-working technique that provides microstructural modification and control in the near-surface layer of metal components. FSP of cast Al and Mg alloys resulted in the break-up of coarse dendrites and seco

Type 316 (UNS S31600) stainless steel (SS) is a candidate alloy for containment of high-level nuclear waste in deep underground storage. The heat-affected zones (HAZs) of welded containers could become sensitized under the appropriate thermal conditi

Grain boundary (GB) solute segregation has long been associated with premature failure of engineering materials. Local changes in composition at the GBs can result in such phenomena as intergranular corrosion, temper embrittlement, intergranular frac

Multipass weld deposits produced with a Mn-modified Type 316L filler material exhibited fracture toughness nearly 100 MPa√m less than that of a conventional 316L filler material when tested at 4.2 K. Although fracture in both materials occurred by

This investigation was designed to study the effect of prior compressive deformation and temperature on the subsequent dynamic fracture toughness, K,Id, of fully pearlitic 1080 rail steel. Charpy instrumented impact tests on precracked specimens were
