PENGARUH QUENCHING DAN MEDIA PENDINGIN TERHADAP SIFAT FISIS DAN MEKANIS BAJA PADUAN FE97,99MN1,60C0,41
ABSTRACT: The mechanical
properties of Fe97,91Mn1,60C0,41 steel
alloy have improved,
especially hardness after been
subjected to various
quenching media. Samples
were heated at austenite temperature 800oC and
2 hours holding time, then quenched in water, oil, and salt water. The
microstructures obtained were
used to explain
the results using
optical microscope. Crystal structure
and hardness were
studied using X-Ray
Diffractometer and Brinell Hardness
Test. The hardness
values of the
quenched samples were
375 HB in
salt water media, 257 HB in water
media, and 231 HB in oil media. Crystal transformation from FCC -austenit to BCT α-martensit were
observed in optical
microscope and 2 peak values of XRD test result.
