“…The reinforcement of materials into AZ31B was based on the weight percentage of Lead (Pb) and CNT materials. The CNT had an outer diameter of 10-30 nm, the density was 2.1 g/cm 3 and it contained more than 90% purity. The Lead powder added contained 99.9% purity with the density of 11.34 g/cm 3 .…”

“…AZ31B + 5% Pb gave the highest increase in terms of strain rate and energy absorption compared to AZ31B + 0.1% and CNT + 5% Pb. This happened because of the composition of CNT 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 reinforced which had not achieved an optimal level and this had led to a weak material structure to structural failure [3,14,19,20]. However, the reinforcement of materials into AZ31B gave positive effects of attenuating in high velocity impact.…”

“…Recent technology development in automotive field requires lightweight material which is high in strength. Exploration of new materials has a high impact in the study of change in strain, especially when subjected to high velocity impact [1][2][3]. Changing strain at high velocity impact affects the material's energy absorption and prevents the occurrence of fracture failure [4][5][6][7].…”

This paper presented the effect of strain rate changes due to Carbon Nanotube (CNT) and Lead addition in Magnesium Alloy, AZ31B on high velocity impact performance. This metal is normally used to fabricate armored vehicle panel. The changing strain will affect the strain rate and had been widely used in automotive applications to accommodate high velocity impact. High strain rate material was applied on the armored vehicle to withstand the impact of the projectile. AZ31B alloy was reinforced with CNT and Lead using Disintegrated Melt Deposition (DMD) method. AZ31B ingots were melted at a temperature of 660 ºC and produced the reinforcement of CNT and Lead during the melting process. Mixed materials were completely inserted into the mold for further process. Microstructure analysis was performed to observe the variance structure of samples. The high velocity impact experiment was performed using a Split Hopkinson Pressure Bar machine. The diameter of the sample was 18 mm with 12.5 mm thickness. The addition of materials such as CNT and Lead into AZ31B had increased the material strain rate. The effect of increasing the strain rate was in line with the increase of energy absorption. The result showed that the strain rate had increased about 30% from the original material, AZ31B and consequently also increased the energy absorption. Thus, the addition of CNT and Lead would increase the strain rate of the original material of magnesium alloy and hence increase the energy absorption capability during impact.

“…Magnesium alloys are attractive structural materials in the automobile industry because of their low density, high specific strength, good castability, and superior creep resistance [1,2]. However, their industrial use has been hampered by their poor high-temperature oxidation resistance [3,4].…”

Pure Mg, Mg-5wt%Ca, and Mg-5wt%Ca-1wt%Zn alloys were cast, and their high-temperature oxidation behavior was investigated to determine the roles of Ca and Zn in oxidation. Ca and Zn additions refined the microstructure by formation of Mg2Ca and Ca2Mg6Zn3, respectively, at grain boundaries. Ca increased the oxidation resistance by forming a thin, compact CaO scale on the surface. However, Zn decreased the oxidation resistance because of the formation of Ca2Mg6Zn3, which increased the MgO-forming tendency. † (
