<p>The influence of ambient temperature regulation coupled with traveling magnetic field (TMF) casting on regulating the solidification process, refining the microstructure, and alleviating the shrinkage defects of Al-7 wt.% Si alloy ingot was explored. The TMF generator and a homemade temperature-controlled mold were employed to prepare the ingots. The thermal curves were monitored using a K-type thermocouple to characterize the phase transition process. The results revealed that the local solidification time and undercooling point of the non-equilibrium solidification process increased as the ambient temperature was elevated. The duration of the forced convection within the melt was found to be 235.1&#xa0;s. Compared with those under No TMF, the average dendrite arm spacing (DAS) decreased from 106.47 to 84.63 μm while the central undercooling point increased from 4.4 to 9.4 °C under the ambient temperature of 200 °C and TMF of 100 A 8 Hz. The sample exhibited a rise in tensile strength (from 100.8 to 122.5&#xa0;MPa), elongation at break (from 6.9% to 10.4%), and microhardness (from 50.5 to 68.4 kgf/mm²). Subsequently, the width reduction in the gap observed on the fractured surface from 103.4 μm to zero corresponded to a 21.5% increase in tensile strength (from 100.8 to 122.5 MPa). This confirmed that eliminating shrinkage defects was the primary mechanism for enhanced mechanical performance. The increase in mechanical properties was attributed to the improvement in feeding capacity of Al-Si alloy melt under the coupling of ambient temperature regulation and TMF. These findings offer an innovative approach to enhancing the mechanical characteristics and solidification structure of ingots through electromagnetic casting in metallurgy.</p>
