Influence of a strong static magnetic field on the discontinuous precipitation reaction in Mg–9Al–1Zn alloy

Effects of elemental additions (Si and Sb) on the ageing behavior of AZ91 magnesium alloy

“…Efforts have been made to improve the age hardening behavior of AZ91 through different routes such as alloying additions, applying magnetic field, external stress, etc. [12][13][14][15]. In many of these attempts suppression of DP reaction was achieved to a greater extend but in all the cases only marginal improvement in peak hardness was noticed.…”

Influence of Electrostatic Field on the Microstructure and Mechanical Properties of AZ91 Mg Alloy during Ageing Treatment

“…Recently, the external energy fields such as magnetostatic or electrostatic fields have been reported to show influences on the heat treatment behavior of Al or Mg alloys. [ 19–24 ] It should be first mentioned that no electric current is generated inside the treated samples by external fields. Li et al [ 19 ] showed that the nucleation rate and the mean growth rate of DP nodule in Mg–9Al–1Zn alloy (in wt%) was decreased by magnetostatic field (intensity 10 T), which was speculated to be due to influences on diffusion behavior.…”

[ 19 ] Hu et al [ 20 ] reported that the solution treatment process of Mg–16.7Gd–0.09Zr alloy was effectively accelerated by the intermediate‐frequency magnetic field (IFMF). The reason was deduced to be that, the alternating magnetic field always generated alternating electrostatic field according to Maxwell's equations, and this electrostatic field accelerated the mobility of electrons and then pulled the positive ions to achieve a new higher equilibrium diffusion rate.…”
