Abstract

In this research we studied the effect of thermal cycles of quenching and
tempering on the adhesive wear resistance of austenitic manganese steel
(9.4Mn1C1.9Cr1Si). The material was characterized chemically and me- tallographically. Subsequently the material was tested by cross cylinder
ASTM G-83 with the aim of determining the adhesive wear behavior. The
results indicate that the specimen tempered at 200 ° C has a longer period
of strain hardening than the ones tempered at 400 and 800 º C, making it
more resistant to wear, thus improving the characteristics of the sample
in a state of supply.
