This paper discusses how the accumulative alternating back extrusion (AABE) process was improved by the addition of water-quench and preheating steps to mitigate the of temperature-drop problem caused by long process flows and the problem of die gap feeding. The effect of the number of extrusion cycles on grain refinement was further investigated to elucidate and rationalize the preferred orientation in AABE. Compression experiments were carried out in tandem to explore the effect of AABE on the mechanical properties of the materials. After eight cycles of AABE, the average grain size reached 5.58 μm, and the fine-grain size reached
