ANALISIS UJI KETAHANAN LELAH BAJA KARBON SEDANG AISI 1045 DENGAN HEAT TREATMENT (QUENCHING) DENGAN MENGGUNAKAN ALAT ROTARY BENDING
Abstract: Fatigue is the one
of the main cause from of the material failure. The main of cause failure 90 %
caused fatigue. Fatigue is material
sructure process changes that is caused by repeatly load (stress or shear) in a
long period of time so it occured crack or break. The reason of this research
is to analyze of the fatigue strength medium carbon steel type AISI 1045 with
variaton of shaft rotation on rotary bending machine. Fatigue test applied on
medium carbon steel type AISI 1045
without heat treatment. This research was conducted with variation of shaft
rotation 2880 rpm and continued with load variation 20%, 30%, 40%, 50% and 60 %
from material UTS. Specimen that used according ASTM E466 spesimen made by
lathe machine. Fatigue test is using by rotary bending machine type fatigue
test machine.
