One Minute Mentor : Phase Transformations in Numerical Simulation

Heat treatment of tool steels means several phase transformations. Every phase transformation must be described by start amount, end amount, and kinetics (change of phases depending on temperature and time). Start and end amount can be calculated with different thermodynamic software. For example, Thermocalc is well validated for tool steels. The most common method for determining the transformation kinetics of main phases (e.g. ferrite, austenite, martensite, bainite) is to use dilatometric investigations. TTT (time-temperature-transformation) diagrams obtained from dilatometer measurements can be easily implemented in HTS software. An example is shown in the figure.

One Minute Mentor: Distortion of Corrosion-Resistant Plastic Mold Steels

Corrosion-resistant plastic mold steels are usually tempered at lower tempering temperatures than hot-work, high-alloyed cold-work, or high-speed steels. A comparison of different types of corrosion-resistant plastic mold steels with the widely used cold-work tool steel D2 with the same dimensions as in the previous example for cold-work tool steels for such heat treatment conditions can be seen in the figure and shows that all steels show a similar low dimension change in width. Regarding the thickness of the plates there is a significantly higher increase for the ledeburitic cold-work tool steel. Vacuum heat treatment with high-pressure gas quenching leads to a similar amount of distortion as salt bath heat treatments but again shows significant scatter.

One Minute Mentor: Distortion of Ledeburitic Cold-Work Tool Steels

The different effects of steel composition on the dimensional change of plates made of ledeburitic cold-work tool steels and a working hardness of 61 HRC can be taken from the figure. Typical representatives of the new generation of improved toughness 8-9%Cr-steels show slightly higher growth in dimension than the classical 12%Cr-D2 steel. 

The growth in thickness (in the rolling direction) is always significantly higher than in width, confirming again the generally known behavior. Salt-bath heat treatment results in higher distortion than various vacuum heat treatments with high-pressure gas quenching, but the results indicate that there is also a significant scatter for gas quenching depending on the detailed quenching conditions.

One Minute Mentor: Distortion of High-Speed Steels

High-speed steels show a typical distortion behavior depending on the heat treatment parameters. The figure shows the change in length of cylindrical bars (diameter = 20 mm, or 0.8 in.) and length = 140 mm, or5.5 in.), with rolling direction longitudinal to the sample) for various heat treatment conditions with austenitizing, salt bath quenching, and double tempering.

Quenching and tempering up to 500 °C (930 °F) results only in very small changes in length (either growth or shrinking). Higher tempering temperatures lead to a transformation of the retained austenite into martensite and a corresponding growth in length. For typical tempering temperature of 560 °C (1040 °F) changes in length of about 0.2% take place. Additional alloying with Co (5%) leads to slightly higher changes in length. The effect of an additional third tempering shifts the curve slightly to the left, whereas oil quenching leads to a slight reduction of the change in length.

One Minute Mentor: Distortion in Tool Steels

Some of the main interactions  that occur during the heat treatment of steel alloys including temperature, microstructure, and stress/strain. Especially for tool steels these interactions are mainly influenced by the carbon content in the steel matrix, the types and relative amounts of the alloying elements, and the carbide formation/transformation/precipitation characteristics of the alloy system.

Heat treatment involves changes of temperature with time, which determine changes in microstructure. The rate of temperature change results in a change of microstructure which is described by phase transformation kinetics, as in e.g. TTT (time-temperature-transformation) diagrams; every phase transformation releases/absorbs latent heat, which influences the temperature field. An inhomogeneous temperature distribution, i.e. temperature gradients, within the tool during heat treatment can generate thermal stresses that lead to plastic deformation, if the yield strength of the material at that temperature is exceeded. Every mechanical deformation generates heat which, in turn, influences the temperature field. Furthermore, there is an interaction between the stress state and the microstructure. Phase transformations can result in micro-plastic deformation, which can be globally described using transformation plasticity models.
