Abstract In the current work, magnesium (AZ91D) matrix composites reinforced with different weight fractions (5, 10, and 15%) of titanium diboride (TiB 2 ) 1.5 wt% carbon nanotubes (CNTs) are fabricated using stir casting. The improvements in mechanical, wear corrosion resistance properties evaluated as per ASTM guidelines. synergistic strengthening effect TiB CNT is also studied. It was discov...

Plates of 3–5 mm in thickness were extracted from an AZ91D ingot and then butt joints of the plates were produced using tungsten inert gas (TIG) welding method. The TIG arc was also used to deposit welding beads on some of the thin plates. No cracking was found in the butt joints. However, hot cracking was always observed to propagate from the heat affected zone (HAZ) under the welding bead int...

To refine the microstructure and improve mechanical properties of AZ91D alloy by expendable pattern shell casting (EPSC), vibration method was applied in solidification process alloy. The effects amplitude pouring temperature on magnesium were studied. results indicated that remarkably improved sizes, morphologies distributions primary α-Mg phase β-Mg17Al12 phase, densification tensile With an ...

In this research, the response of AZ91D granules during In-Situ melting as a novel technique for investment casting of magnesium alloy was investigated. In order to assess the melting behaviour, the granules were heated at 700 °C for 30 min under three different protective environments, including covering flux, argon atmosphere and their combination. Thermal analysis experiments were carried ou...

A systematic study was carried out to evaluate the correlation between high pressure die casting (HPDC) parameters and the mechanial properties of Magnesium alloys. The tested alloys included two conventional alloys: AZ91D and AM50A and a newly developed alloy, RI153M. The nature of the above correlations was semi-empiric, based on computer simulation of the die casting process using MAGMA® sim...

Recently magnesium alloys, owing to their low density and excellent specific strength have been attractive to designers as an advanced material for coping with energy conservation and environmental pollution regulations. Much of the recent developments of magnesium alloys and processes have been driven by the requirements of the aerospace industry, although some successful ones have found appli...
