Conclusions
-
1.
The total deformation of a sample under the influence of thermal cycling and uniaxial stress characterizes the resistance to thermal fatigue of die-casting molds.
-
2.
Experimental determination of the deformation makes it possible to calculate the number of cycles to failure of die-casting molds due to thermal fatigue.
-
3.
Calculating the thermal fatigue by the method proposed makes it possible to compare different steels. It is recommended that these calculations be made in selecting materials for die-casting molds.
-
4.
Maraging steel N21M2T2B is a promising material for die-casting molds used for aluminum alloys.
