Web1 Jan 2024 · The findings indicate that the modified alloy had adequate thixoformability in that it had a larger working temperature window, lower temperature sensitivity to liquid fraction content, and wider solidification range than those of the commercial A319 alloy. Both alloys work in semisolid state. Aluminum thixoforming occurs between 500 degrees C and 650 degrees C, while steel thixoforming requires a temperature of about 1,400 degrees C. Thethixoform window is much narrower for steel—it's only about 30 degrees C, compared to the 150-degrees-C window in aluminum thixoforming.

"Web31 Dec 2009 · A range of steels is normally industrially available. The question here is to identify those which are most suitable for thixoforming and to adapt the composition to maximise the chances of success. In this chapter, the influence of alloying elements on the solidus and liquidus temperatures and on the thixoforming window is identified. " - Thixoforming window

WebThe heat treatment by thixoforming increases the hardness of the Al-Si alloys from 61 HV to 99.85 Hv. The shear force breaks the dendrite arms of the primary α-Al phase and refines the grains. The Al-Si alloys show a smaller and denser microstructure after the cooling slope condition, having a higher microhardness than the as-cast Al-Si alloy sample [ 41 ].
