Improving Mechanical Properties of Mg-Al-RE Alloys with the Formed Dimples of AlMnRE Particles and Activated Pyramidal <> Slip with Mn Additions.

The effects of Mn addition on the room temperature tensile strength and deformation mechanisms of as-cast Mg-8Al-1Nd-1.5Gd-Mn alloys ( = 0, 0.3, 0.

Effect of TiB Nanoparticle Content on the Microstructure and Mechanical Properties of TiB/Mg-4Al-1.5Si Composites.

Coarse primary and eutectic MgSi phases were generally precipitated in Mg-Al-Si alloys during solidification at a low cooling rate, which tends to deteriorate the strength and ductility of magnesium alloys due to stress concentration. Different volume fractions of TiB nanoparticles (1%, 3%, and 5%) were added to an Mg-4Al-1.5Si alloy to refine the coarse MgSi phases based on a heterogeneous nucleation mechanism.

Microstructure, Interface and Strengthening Mechanism of Ni-CNTs/AZ91 Magnesium Matrix Composites.

Ni-CNTs/AZ91 magnesium matrix composites were fabricated by ultrasound treatment combined with a semi-solid stirred method for the first time. The agglomerated spherical Ni-CNTs transferred from spherical shape to clear tubular shape after pre-dispersion treatment. For the Ni-CNTs/AZ91 magnesium matrix composite prepared by semi-solid stirring followed by ultrasonic treatment, Ni-CNTs were evenly distributed in the magnesium matrix or wrapped on the β (MgAl) phase.
