Abstract

H13 steel suffered periodic heating and cooling when used as die casting mold materials, and this will leading to emerge thermal fatigue easily. To solve this problem, this paper studied the thermal fatigue process of die casting mold steel by comparing the results of thermal fatigue test and ANSYS simulation method, and try to predict the initiation and propagation of thermal fatigue cracks. In this paper, HMTH1 thermal fatigue testing machine was employed to heat and cool the specimen in periodicity, and recorded the cycle times and crack lengths when thermal fatigue cracks were observed. The ANSYS software was used to complete finite element simulation of the experiment and obtain the result of temperature fields, heating stress fields and cycle crack paths of different thermal fatigue cycles. The result indicated that as the thermal fatigue cycles up to 500 and 1000, the main crack propagated 567.29μm and 225.29μm, and compared the simulation result under the same conditions to solve the problem of initiation and propagation of thermal fatigue cracks better.
