Semi-Solid Casting of High-Reactive Wrought Alloys by Means of the Alloy AlLi2.1Mg5.5ScZr (AA1420*)

Abstract:

Semi-solid forming offers new potentials for processing of high reactive and hot crack susceptible aluminium-lithium wrought alloys. With the tailored alloy AA1420* (AlLi2.1Mg5.5 +Sc+Zr) a promising material for thixoforming with achievable high strength of up to 500MPa tensile strength and over 400MPa yield strength concomitant with its low density of 2,46g/cm3 is achievable. Due to high solid fractions the effect of solidification shrinkage could be sufficiently decreased with the result of hot-tear-free casting. Simulation supported a critical to cast automotive tie rod was exemplarily manufactured via semisolid- technology with promising results. Furthermore with an improved and advanced heat treatment enhanced mechanical properties, comparable to those of rolled AA1420, were achieved.
