| Summary: | This paper focuses on improving energy absorption through a series of heat treatment and quenching in medium,
presence of nanoparticle. The characterisation of the experiment was to determine the suitable combination of
composition factors: temperature, soaking time, and the medium that consist of nanoparticle on magnesium alloy
surface structure to improve the energy absorption using quenching in nanofluids. The diameter and thickness of the
specimen are 6 mm and 10 mm, respectively. All specimens undergo heat treatment based on the temperature of the
furnace and the soaking time of the specimen in the furnace, which will be submerged into three medium distilled water,
and the addition of a 0.1% wt carbon-nanotube (CNT) and 0.1% wt nano-silica. The addition of CNT and nano-silica
shows an increment of 106.68%% and 59.30% for energy absorption, respectively, when compared to the controlled
sample. Later microscopy has performed on the specimen to correlate the addition of nanoparticles in the heat treatment
and improved energy absorption by EDS analysis on the material composition on the specimen’s surface. Therefore, this
paper reveals factors of heat treatment and the presence of CNT and Nano silica effects on enhancing magnesium alloy
energy absorption: UTS and yield strength using quenching method.
