Mechanical properties of magnesium alloy (AZ31B) with ceramic nanoparticles reinforcement
The mechanical properties of AZ31B alloy and AZ31B matrix with ceramic (SiC) nanoparticles reinforcement with particle size of 60nm and volume fraction of 1% have been studied from low to high strain rates. The strain rates have been studied and tested are 0.001 /s, 700 ± 50 /s, 1400 ± 100 /s, 2350...

| Summary: | The mechanical properties of AZ31B alloy and AZ31B matrix with ceramic (SiC) nanoparticles reinforcement with particle size of 60nm and volume fraction of 1% have been studied from low to high strain rates. The strain rates have been studied and tested are 0.001 /s, 700 ± 50 /s, 1400 ± 100 /s, 2350 ± 200 /s and 2800 ± 200 /s. The quasi-static (low strain rate) and dynamic (high strain rate) compression testing were carried out by INSTRON machine and Split Hopkinson Pressure Bar (SHPB) respectively.
The vital mechanical properties in engineering applications such as compressive yield strength, compressive strength, ductility and toughness & energy absorption were examined and analysed for both of the materials. The results comparison between AZ31B alloy and AZ31B with SiC particles- reinforced nanocomposite for low and high strain rates testing shown that the AZ31B alloy as a matrix with addition of small fraction of SiC in nano-sized composite had significant increase in the mechanical properties stated above. Therefore, the enhancement in those mechanical properties of AZ31B with SiC-reinforced nanocomposite have proven that its potential to replace the existing metals and alloys for various automobile, aerospace and other engineering applications. |
