Northwestern University awarded with first prize by using Thermo-Calc
The ASM Materials Education Foundation introduced the Undergraduate Design Competition 2007 as a part of the growing importance of materials design.
First prize was awarded to Northwestern University, Evanston, Ill., for “Stentalloy 2000: High-Performance Superelastic Alloy for Medical Applications.”
Highlights: Motivated by performance requirements of future medical stent applications, collaboration of a Materials Design class project team with Senior Project experimental research addressed design of novel TiNi-based superelastic shape memory alloys employing nanoscale precipitation strengthening to minimize irreversible accommodation slip for cyclic stability and to increase output stress capability for smaller devices.
A thermodynamic database and special software (Thermo-Calc Software Inc., McMurray, Pa.) were used to model the evolution of phase composition in the Al-Ni-Ti-Zr system, including coherent phase precipitation from a supersaturated TiNi-based matrix in a 50Ni-38Ti-4Al-8Zr (at.%) alloy. Based on measured evolution of the alloy hardness (under conditions stable against martensitic transformation) a model for the combined effects of solid solution strengthening and precipitation strengthening was calibrated, and the optimum particle size for efficient strengthening was identified. This model and others were combined to allow Thermo-Calc-based design of optimized alloys with low-misfit coherent precipitation strengthening, desired transformation temperatures, and enhanced radiopacity absorption. Extension of alloy designs to incorporate platinum for reduced nickel content and enhanced radiopacity also were considered. A proposed 49Ni-33.4Ti-11.6Zr-5Al-1Pt alloy with 1000°C solution treatment and 600°C aging is predicted to provide strength greater than 2000 MPa with low misfit, a transformation Af temperature of 15°C for desired superelastic behavior at body temperature, and a radiopacity absorption 43% greater than that of current TiNi alloys.
