Abstract: The development of thermal stresses in ingots during the vacuum arc remelting (VAR) as well as specialized permanent mold casting (PMC) process was modeled via numerical solution of the ...

Abstract: The design of cans to produce uniform, defect-free gamma titanium aluminide alloy pancakes via conventional, nonisothermal forging, was established using finite element modeling (FEM) and laboratory ...

Abstract: The development of temperature gradients and thermal stresses during the heating of large ingots has been investigated with special reference to the selection of heating schedules for brittle ...

Abstract: An investigation of heat transfer and friction during hot forging has been performed using experimental and analytical techniques. The interface heat transfer coefficient was measured in experiments ...

Abstract: 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 ...

Abstract: The application of the ring test to assess die-workpiece interface friction during forging of powder metallurgical materials has been investigated. As for fully dense materials, the change in ...

Abstract: Experimental and analytical techniques have been developed for the determination of the interface heat transfer coefficient for nonisothermal bulk-forming processes. A fixture consisting of two ...
