Abstract :
Austempering is the process of isothermal transformation of steel at temperatures between the pearlite phase and the martensite phase. The austempering time must ensure that the formation of bainite ferrite is sufficient for the remaining austenite with carbon which allows most of it to be maintained to room temperature. Austempering is intended to form strong and resilient material. To determine the effect of temperature variations on the austempering process, the tests conducted are tensile testing, fatigue testing and microstructure observation. Tensile test values after undergoing austempering at temperatures of 320 ° C, 350 ° C and 380 ° C are 119.47, 127.86 and 134.34. While the strain value is 1.39, 1.74, 2.43. The cycle produced by fatigue testing in the process at temperatures of 320 ° C, 350 ° C and 380 ° C, namely 130600 cycles, 166200 cycles, 185700 cycles.
