...J. C. Gelin; Th. Barriere; J. Song The paper is concerned with occurrence of processing defects and resulting mechanical properties associated with material processing by metal injection molding (MIM). MIM process is a multistep one that consists first in the injection of metallic powders mixed...

...J. O. Obielodan; G. D. Janaki Ram; B. E. Stucker; D. G. Taggart Two types of defects normally occur in ultrasonically consolidated parts: (i) Defects that occur between mating foils in successive layers (“type 1” defects) and (ii) defects that occur within a layer between two foils laid side...

...S. L. Semiatin; P. D. Nicolaou; J. P. Thomas; T. J. Turner Mechanism-based models for the evolution of defects during the thermomechanical processing of aerospace titanium- and nickel-based alloys are reviewed. These defects include those comprising microstructural/metal-flow irregularities...
