| Abstract: | Surface hardening such as solid
carburizing is well known in the engineering field
and the basis of this action is to extend the life
span of machines and other metal structures in
order to cope with economic demand. The
objective of this research is to study the fracture
toughness in low carbon steel using two types of
specimen: compact tension and bend specimens,
with and without carburizing. For compact tension
specimen, three types of testing methods were
done: tensile test to get the maximum load, fatigue
pre-cracking test to prepare the specimens with
pre-crack within 2mm to 2.5mm, and fracture
toughness test to complete the finding. On the
other hand, there were also three types of testing
methods done for bend specimen: flexural test to
determine the maximum load, fatigue precracking
test to obtain the number of cycles
needed to create a pre-crack and three point
bending test to determine the fracture toughness.
INSTRON 8802 universal testing machine was
used to conduct all testing methods. Two different
formulas to gain the fracture toughness were
implemented for both types of specimens. The
formulas were referred from ASTM E399 Guide
Book for fracture toughness determination. |
