MatILDa Material Database
The material data base for realistic material simulation
MatILDa® (Material Information Link and Database) is a material database containing experimental data that has been continuously developed by GMT mbH for over twenty years. The data are based on practical material investigations and are therefore highly accurate. The material database offers an extensive material archive with a wide range of visualization functionalities, for example flow curves and ZTU diagrams. This knowledge is also accessible to FEM simulation programs via special interfaces.

Precise mapping of processes made possible by realistic material data

The MatILDa® material database is used for simulating material behavior in forming processes and during heat treatment. The more accurate the data available in a material database, the higher the degree of consistency of the simulation results with reality. In this respect, the MatILDa® material database offers clear advantages over other databases, as it provides physical and mechanical properties for a wide range of materials and offers realistic calculation options for flow curves, grain sizes and transformation diagrams.
Why MatILDa® is so innovative
The software contains an extensive collection of material data, in particularly from a large number of experimental tests. Using data-based models such as neural networks, MatILDa® calculates properties of steels even with deviating chemical composition.

The open nature of the database is unique. Users are able to integrate, create and manage their own material data sets. If required, we are available to provide individual consultation. Efficient program libraries further allow the material data and models to be integrated into user-specific software. Thus, MatILDa® can be used as a stand-alone program or together with simulation systems.

What the MatILDa® material database is capable of
MatILDa® is an innovative material database containing an extensive collection of material data for the simulation of material behavior in forming processes and during heat treatment. This material data, the majority of which has been acquired experimentally, can be used in a wide range of simulation programs, FEM programs and individual process software, and enables the material behavior to be simulated accurately. MatILDa® thus enables a realistic representation of your process. Extensive information can be retrieved for a wide range of steels, non-ferrous metals and special materials:

✔ Flow Curve Database: Flow curves and material properties based on experimental data.
✔ Analytical models for the description of recrystallization behavior
✔ Phase transformation models using neural networks
✔ ZTU diagrams

MatILDa® is a material database with a high degree of flexibility in export
Data exchange is uncomplicated by using export files or by directly connecting to simulation software. Furthermore, MatILDa® can be used as a stand-alone program. In so doing, material data can be managed and supplemented on a company-specific basis.
Details on the functional scope of the MatILDa® material data base
MatILDa®'s main field of application is in the simulation of material behavior (material simulation). The database is a comprehensive and reliable basis for making cost-efficient and precise statements on material behavior and property formation, for example on:

• the influence of chemical analysis on the most important material properties,
• the material properties resulting from forming processes,
• the mechanical and physical properties as a function of temperature, and
• the microstructure (e.g. grain size) and the phase transformations (e.g. phase fractions of, for example, ferrite, pearlite or bainite) during forming and cooling.
The material database with interactive interface and numerous visualizations.
Using an interactive interface, the data can be visualized and the influences of individual settings of the respective model parameters can be simulated with practical controllers.
Process simulation with realistic material data for a wide range of applications
The MatILDa® material data base is used by a large number of our customers from various industries, whether to support offline or online process models or as a database for FEM simulation. The most common areas of application are:

✔ solid forming (hot rolling, cold rolling, production of long products, cross rolling, cross rolling)
✔ open die and closed die forging
✔ various heat treatment and hardening processes, including thermomechanical treatment
✔ cold forming

In principle, the material data can be used in all forming and heat treatment processes. Please do not hesitate to

Why a material database?
The advantages of a material database are obvious: Use experimental data from the MatILDa® material database for realistic simulation results! Keep material data of various alloys in a material database ready for your optimization projects and manage your own, company-specific material data in the material database.
Why real and exact material data of a material data base are so important.
Flow Curve Database
The MatILDa® software provides, of course, extensive flow curves in tabular and analytical form, as well as material properties based on experimental data.
ZTU Database
As a foundation for transformation modeling, experimentally recorded ZTU diagrams are available in the ZTU database of MatILDa® for a variety of steel grades in the form of continuous, isothermal, welding and cooling ZTU diagrams.
Phase transformation
In addition, it is possible to model the phase transformation on the basis of extensive ZTU data evaluation for arbitrary cooling sequences: neural networks allow the microstructure quantity fractions and hardness to be determined for a number of steel groups on the basis of the chemical analysis and the austenitizing temperature.
