Abstract

Metal injection molding has been used to form laminated tungsten heavy alloys of different compositions (85W12Ni3Fe, 90W8Ni2Fe, 95W4Ni1Fe ). The alloy difference between the layers induces tensile and compressive stresses in the sintered condition. This paper demonstrates that multilayer heavy metal structures can be fabricated without defects. Two and three layer laminates were prepared and the stresses were predicted using laminate theory and compared to the x-ray diffraction stress measurement. Residual stress differentials of up to approximately 100 ksi have been measured. Laminate theory, using measured material properties, predicts these stress differentials to be approximately 150 ksi.
