Abstract EN
AISI 4140 alloy steel is widely applied in the manufacture of various parts such as gears, rams, and spindles due to its good performance of strength, toughness, and wear resistance.
The former researches most focused on its deformation and recrystallization behaviors under high temperature.
However, the evolution laws of austenite grain growth were rarely studied.
This behavior also plays an important role in the mechanical properties of parts made of this steel.
In this study, samples are heated to a certain temperature of 1073 K, 1173 K, 1273 K, and 1373 K at a heating rate of 5 K per second and hold for different times of 0 s, 120 s, 240 s, 360 s, and 480 s before being quenched with water.
The experimental results suggest that the austenite grains enlarge with increasing temperature and holding time.
A mathematical model and an application developed in Matlab environment are established on the basis of previous works and experimental results to predict austenite grains size in hot deformation processes.
The predicted results are in good agreement with experimental results which indicates that the model and the application are reliable.
