Az31b Alloy

In the recent decades, magnesium matrix composites present a plenty of applications to automotive, marine and aerospace industries. In this work, AZ31B is selected as Mg matrix material and hard Tungsten carbide (WC) particles as reinforcement material. Mg/WC composites reinforced with different weight proportions (0, 5, 10 and 15 wt.%) were made through stir casting method. The worn surface of manufactured Mg/WC composites and base Mg material were examined by scanning electron microscope (SEM). The wear test results denoted that the AZ31B/15 wt% WC composites have excellent tribological behaviour when compared to the base magnesium matrix AZ31B alloy. The yield strength, flexural strength, tensile strength and micro-hardness of the manufactured composites are improved by increasing the WC content. SEM images reveal the homogeneous distribution of WC particles throughout the Mg matrix.

In this work, AZ31B is selected as Mg matrix material and hard Tungsten carbide (WC) particles as reinforcement material. Mg/WC composites are reinforced with different weight proportions (0, 5, 10 and 15% wt.) using stir casting method. The worn surface of manufactured Mg/WC composites and base Mg material were examined by scanning electron microscope (SEM). The wear test results denote that AZ31B/15% wt. WC composites have excellent tribological behaviour when compared to the base magnesium matrix AZ31B alloy. The yield tensile strength, flexural strength, ultimate tensile strength and micro-hardness of the manufactured composites are improved by increasing the WC content. Further, SEM analysis revealed the homogeneous distribution of WC particles throughout the Mg matrix.

Infiltration Method

Aluminum borate whisker (9( Al 2 O 3)·( B 2 O 3)) reinforced AS52(with and without strontium modification) metal matrix composites (MMC) were fabricated by the squeeze infiltration method. Creep rupture test was carried out at 150°C and 100 MPa condition. Results showed that Alborex reinforcement and modified polygonal shape Mg 2 Si phase contributed to the enhancement of mechanical properties and creep resistance. Creep rupture time was increased 11% and minimum creep rate was decreased 17% in the composite. At the Alborex/matrix interface, uniform thin layer of MgO was formed. The initiation of micro-voids at the reinforcement/matrix or Mg 2 Si /matrix interface was followed by their growth and coalescence to macro-cracks.
