Abstract
ABSTRACT
In the article, the computer modelling of the energy states of the probe during
quenching process in the Isomax 166 oil is presented. The probe was cooled from the
initial temperature of 850 °C. The selected steady-state temperatures of the oil were
from 0 °C to 120 °C. The material of the probe was non-stabilized Cr-Ni austenitic
stainless steel 1Cr18Ni9. The simulation model involves nonlinear thermophysical and
thermomechanical material properties. Cooling curves were obtained using the
methodology of Wolfson test. Based on the numerical simulation of a cooling process
and experimental temperature measurement, the combined heat transfer coefficient
was calculated. To determine the combined heat transfer coefficient as a function of
probe surface temperature, the inverse-numerical-correlation method was applied. The
time histories of thermal elastic and plastic stress states, time dependences of residual
stresses and volume plastic work as a function of chosen temperature of quenching oil
were analysed using the finite element method and the engineering-scientific program
code ANSYS.
