Abstract:The effect of a pulsed magnetic field on the microstructure of a QAl9-4 aluminium bronze alloy was studied in this work. It was found that the dislocation density, grain boundary angle, and microhardness of the alloy significantly changed after the magnetic field treatment with a peak magnetic induction intensity of 3T, pulse duration of about 100 us, pulse interval of 10 s, and pulse time of 360. EBSD was used to test the KAM maps of the alloy microzone. It was found that the alloy’s dislocation density decre… Show more
“…Hu et al [ 24 ] contributed a paper entitled “Effect of Pulsed Magnetic Field on the Microstructure of QAl9-4 Aluminium Bronze and Its Mechanism”, in which it was found that the dislocation density, grain boundary angle, and microhardness of the alloy significantly decreased after the magnetic field treatment; this may have resulted from the transition to the electronic energy state at the site of dislocation pinning caused by the pulsed magnetic field, leading to free movement of the vacancy or impurity atoms.…”
