Title: Experimental Investigation and Numerical Simulation During Backward Extrusion of a Semi-Solid Al-Si Hypoeutectic Alloy

Abstract

This work has been performed along two main directions. First of all we present the experimental results and effects obtained by backward extrusion tests on semi-solid aluminum alloy at three different forming temperatures and different holding times in isothermal conditions. The semi-solid billets were fabricated by the re-melting heat treatment method. Semi-solid extrusion tests were carried out to investigate the load-displacement curves and the deformation behaviour at different temperatures. The load level clearly decreases with increasing temperature and increasing holding time. Numerical simulations of semi-solid extrusion has been made too, using Forge 2005,. Experimental and simulated results are compared and discussed.

  • The evolution of strontium (Sr) containing intermetallic phase in the eutectic reaction of Sr-modified Al-Si hypoeutectic alloy was studied with high energy synchrotron beam source for nano-diffraction experiments and x-ray fluorescence elemental mapping. Contrary to popular belief, Sr does not seem to interfere with the Twin Plane Re-entrant Edge (TPRE) growth mechanism of eutectic Si, but evolves as the Al{sub 2}Si{sub 2}Sr phase during the eutectic reaction at the boundary between the eutectic Si and Al grains.
  • Semi-solid state processing is considered as an attractive processing technique because of it offers several potential advantages such as energy saving for forming, reduction of microsegregation and porosity, especially for near net shape manufacturing of components. This technique is frequently applied to make sound casting products of hypoeutectic Al-Si alloys. On the other hand, hypereutectic Al-Si alloys have limited applications because of their inherent problems associated with poor machinability and mechanical properties, although the commercial potential for their outstanding resistance to wear and corrosion, higher hardness and low coefficient of thermal expansion is well recognized. To exploit the full potentialmore » of hypereutectic Al-Si alloys, semi-solid processing is utilized in an attempt to improve the mechanical properties through the spheroidization of primary Si crystals. The purpose of the present work is to provide the experimental evidence of the fragmentation of primary Si crystals in hypereutectic Al-15.5wt%Si alloy during semi-solid processing. Microstructural evolution during the isothermal shearing above the eutectic temperature of this alloy as a function of processing time is also reported.« less
  • There are few experimental and kinetic studies of equiaxed-dendrite nucleation and growth in the mushy zone during the solidification of liquid metal alloys. Existing studies have either tried to deduce the solidification kinetics and mechanism from the final as-cast structure or to simulate the development of the grain structure using transparent organic solutions. These methods have short-comings in that they cannot account for various phenomena such as dendrite fragmentation, coarsening or grain refining. Pedneau et al have recently developed a method for the in-situ and real-time investigation of equiaxed-grain growth in the mushy zone during solidification. The method is basedmore » on the Electrical Sensing Zone (ESZ) technique, and allows for the monitoring of the density and size distribution of equiaxed grains in aluminum alloys during solidification. In this paper, the application of the ESZ method to monitor equiaxed grains within the mushy range of Al-Si alloys is described. When the alloy is within the hypoeutectic region of the Al-Si binary system, the first equiaxed grains to form are primary {alpha}-Al which are more conductive than the melt in which they form. Hence G(k) is negative and negative pulses are obtained. When the alloy is within the hypereutectic range, the first phase to form is the primary silicon which is of much higher resistivity than the liquid aluminum. Then, G(k) equals one and positive pulses are obtained.« less
  • Shear deformation behavior in a wide temperature range of 683--893 K and at 2 {times} 10{sup {minus}3}{minus}3/s for a high strain rate superplastic Si{sub 3}N{sub 4p}/Al-Mg-Si composite is described. The dominant deformation mechanism was dislocation creep at 683--773 K, superplasticity containing no liquid phase at 813--823 K, superplasticity containing a liquid phase at 833--863 K and deformation related to the liquid flow at 873--893 K, respectively. In the superplasticity region, the shear strain to failure was significantly increased by the presence of a discontinuous liquid phase. At 873--893 K, high m of about 1 was attained. The deformation in thismore » temperature range is likely to be the lubricated flow in a semi-solid state containing a continuous liquid phase. However, ductility was low in this region. This is probably because of decohesion at boundaries with a thick liquid phase.« less
  • A reciprocating extrusion (RE) process has been developed for producing Al-12 wt pct Si bulk alloys with fine and uniform microstructures and superior properties. Two starting forms were used: disks produced by the hammer-and-anvil method and cast billets produced by casting. Variations of microstructure and mechanical properties with the number of extrusion passes are investigated for these two starting forms. The results show that the porosity along the interfaces between the rapidly solidified layers could be completely eliminated to give a sound matrix. The Si-phase particles in both cases could be refined and distributed uniformly. The strength and ductility ofmore » all specimens are also enhanced, until the microstructure reaches an optimum state, as the number of extrusion passes increases. The tensile properties of the rapidly solidified Al-Si alloys are found to be superior to those of ingot-processed alloys, due to the inherent finer particles produced by rapid solidification. The mechanism for the improvement of the microstructures and properties is also discussed.« less
