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 Ledeburitic Cold-Work Tool Steels

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 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.

Constellium’s Muscle Shoals facility receives Department of Defense grant to increase casting capacity

Constellium, Muscle Shoals, AL, announces that its facility has been selected by the U.S. Department of Defense (DoD) for a $23 million investment under Title III of the Defense Production Act to rebuild its Direct Chill aluminum casting center.

The funding was awarded via the Defense Production Act Investments (DPAI) Program, overseen by the Manufacturing Capability Expansion and Investment Program (MCEIP) in the Office of the Assistant Secretary of Defense for Industrial Base Policy. Constellium will use the funds to install state-of-the-art casting equipment on the site of a dismantled casting center, adding up to 300 million pounds of annual casting capacity. With this added capacity, the plant expects to increase its recycled input, reduce its use of primary metal, and provide the U.S. industrial base with an additional, self-reliant domestic source of supply for aluminum rolling ingot.

“This investment under the Defense Production Act will enable our industry to meet the rapidly increasing demand for the aluminum products needed not only for our national security but also necessary for the overall U.S. manufacturing sector and a healthy economy,” commented Buddy Stemple, President of Constellium Muscle Shoals. “We are very excited to have this opportunity to partner with the DoD to help strengthen our industrial base.”

Constellium Muscle Shoals is a major aluminum sheet supplier for the packaging and automotive markets. The plant has the capacity to produce over 1 billion pounds per year of finished aluminum coils. Muscle Shoals also operates a world-class recycling center able to recycle the equivalent of 20 billion aluminum cans per year.
