The mechanism of tensile failure in a nickel-base casting alloy
A. J. Lewis
Standard tensile specimens were cast from a nickel-base partial denture
casting alloy and subsequently fractured in a tensile stress testing
machine. Fracture sites were subjected to scanning electron microscopy in
order to determine the exact mechanism by which failure had occurred. A
metallographic examination of prepared specimens was used to demonstrate
the distribution of phases within the alloy.
