Investigation of the effects of intense pulsed particle beams on the durability of metal-to-plastic interfaces.

Description: We have investigated the potential for intense particle beam surface modification to improve the mechanical properties of materials commonly used in the human body for contact surfaces in, for example, hip and knee implants. The materials studied include Ultra-High Molecular Weight Polyethylene (UHMWPE), Ti-6Al-4Al (titanium alloy), and Co-Cr-Mo alloy. Samples in flat form were exposed to both ion and electron beams (UHMWPE), and to ion beam treatment (metals). Post-analysis indicated a degrada… more

Effects of heat treatment on the microstructure and mechanical properties of uranium-6 niobium alloy

Description: Aging studies on uranium-6 weight percent niobium alloy were performed at temperatures of 500 and 600/sup 0/C. Mechanical-property measurements and microstructural analyses were used to characterize the aging response of the alloy. An attractive combination of mechanical properties was produced by aging at 550 to 600/sup 0/C; namely, a 0.2% offset yield strength greater than 730 MPa with an elongation of 15 to 18%. Increasing the aging time at temperature minimized the variability in mechanical… more
