INVESTIGASI PERBEDAAN SUHU TUANG TERHADAP SIFAT MEKANIK DENGAN PENGUKURAN KEKERASAN DAN IMPACT PADA PADUAN AL 2024
ABSTRACT: Aluminum alloys have
high strength to weight ratio, tough enough, resist to fatigue crack propagation,
easy to cast, corrosion resistant and recycle. High strength to weight ratio
means an efficient, strong and capable of long-lived, economical and
environmentally friendly. In the application as a frame structure, mechanical
properties are something that must be considered. Therefore, the researchers
tried to find the effect of pouring temperature differences in Aluminum 2024
through hardness test and impact test. For the investigation at three different
temperatures of 688 o C, 738 o C, 788 o C, the gravity casting method is used
to produce a plate-shaped object. The test results showed an increase in
hardness, with the highest value of 103.71 BHN at a temperature of 738 C and impact test results with the highest value of 4.9 Joule
at temperatures of 738°C.
