Reference books

The collection of time-temperature transformation diagrams (TTT) and time-temperature austenitizing diagrams (TTA) from the years 1958-1974, presented with the Heat Treatment Atlas, is a tremendous practical aid in the design of heat treatments even decades after their appearance.

In the first and third volume metrological methods, materials science basics as well as a variety of continuous and isothermal TTT diagrams are compiled.

The aim of the 3rd and 4th volumes is to provide the heat treatment specialist with documents that enable him to estimate the results of time-temperature processes in the rapid heating of steel, for example inductive heat treatment, with sufficient accuracy. The collection was published by the Max Planck Institute for Iron Research (MPIE) in collaboration with the Technical University of Berlin and the Materials Committee of the Steel Institute VDEH.

Precipitation Atlas of Steels

The "Precipitation Atlas of Steels" was put together as a joint effort by the working group electron microscopy of the Materials Committee of the Steel Institute VDEh. In a representation (600 pages), kept as short as possible by the text and image, the reader finds everything essential about the precipitations and their influences and associated analysis methods (SEM, TEM, etc.) that occur in certain steels and steel groups.

Registration Stahl-Eisen-Liste (Register of European Steel) according EN 10027-2

Producer can register here new steels in the Stahl-Eisen-Liste.

For the allocation of material numbers, which are primarily characterized by their chemical composition,
please use Form 1.

For the allocation of material numbers, which are primarily characterized by their mechanical properties,
please use Form 2.

Sheet steel database

The reference with characteristic values ​​and raw data

In several joint projects of the steel and automotive industry "Development of material- and processing-compatible characteristic values ​​for thin sheet of normal and high-strength steels and stainless steels", design-relevant parameters were determined under the direction of the Steel Institute VDEh on relevant body steels.

Materials

The database contains the main sheet steel materials for vehicle construction, which are linked to the corresponding tests:

  • LC steels, IF steels
  • deep drawing steels
  • Bake-Hardening steels
  • Micro-alloyed steels
  • High strength steels
  • DP steels
  • TRIP steels
  • austenitic steels

The steels were investigated both in the initial state and in defined pre-deformation and heat-treatment conditions.

Tests

Contents are thousands of real traces and stress-strain diagrams:

  • Bulge exams
  • Dynamic tests
  • Elastic tests
  • Plastic test
  • Cyclic test
  • boundary shape change

Hardenability curves

The underlying models are valid for a limited range of chemical composition, which is displayed with. Within the validity periods, the user can generate as many hardenability curves as they like and export them from the system - the standard display corresponds to the mean value analysis The hardenability calculation is part of the StahlDat SX standard version.


Calculation of hardenability

Calculate forehead quenching hardness (Jominy test) from the chemical analysis

All Steel Iron Test Sheet 1664 models: 2013 The Steel Iron Test Sheet SEP1664-2013 provides regression models for the calculation of hardenability for the following material groups:

  • Cr-tempered steels
  • CrMo tempered steels
  • MnCr insert steels
  • MnCr hardened steels higher strength
  • MnCrB tempered steels
  • MnCrB insert steels
  • CrNi insert steels
  • CrNiMo Case Steels (2003)
  • MoCr Case Steels (2012)
  • CrV tempering steel
  • C-tempered steels
  • CrB tempered steels
  • AFP steels
  • chain steels

TTT database

Data and literature for the heat treatment of steels Unlike the previous Stahldat, the new Stahldat SX contains a continuously growing number of TTT and TTA diagrams.

With the StahlDat SX TTT database, finding suitable data is particularly easy:

  • Search for chart type and austenitizing conditions
  • Search for names and chemical composition
  • Similarity search with ranking
  • Tabular comparisons of different diagrams

Flow curves database

More than 500 models for cold and hot forming

The flow curves were kindly provided by the Institute for Metal Forming of the TU Bergakademie Freiberg. They are the result of decades of experience in this field and are also internationally regarded as a solid basis for the design of forming processes.

Flow curves

All flow curves are parametric models (Hensel-Spittel, IMF TU Freiberg) with the parameters temperature, degree of deformation and deformation rate. Within the scope of the validity of the models, any flow curves for steel can be generated and compared with each other. In addition, relationships with other steel data, e.g. chemical composition and thermophysical properties, with the extensive analytical capabilities of the StahlDat SX Professional. Flow curves characterize the forming behavior of steels. They serve as a basis for the calculation of forces and the workload during forming. For example, e.g. the result of a finite element simulation largely depends on the quality of the flow curves used. The flow curve is the representation of the yield stress as a function of the logarithmic main shape change at constant other parameters such as temperature and strain rate.

Flow curves are available for more than 150 steels for different microstructure states. The flow curve database is directly linked to the materials of the Register of European Steels.

Thermophysical data

based on the 100 steels program of Friedhelm Richter Investigated properties / measuring methods and measuring instruments

  • Density

The density was determined by weighing in air and under water using a thermostated semi-microbalance.

  • Thermal expansion

For measuring the thermal expansion, i. the average linear thermal expansion coefficient and the differential linear thermal expansion coefficient, a specially constructed Dilatometermessplatz was used with vertical sample positioning.

  • Young's modulus and transverse contraction number

The two elastic sizes, the modulus of elasticity and the transverse contraction number, were recorded by measuring the resonance frequencies of free-swinging rod-shaped samples. The "dynamic" quantities determined in this way can differ from the "static" sizes, in particular at higher temperatures, as determined in the tensile or bending test. For these investigations, the measuring arrangements with the designation "Elastomat" and "Tectanel" were available.

  • Specific heat capacity

An adiabatic calorimeter was used to determine the heat content and thus the true specific heat capacity and the average specific heat capacity. The recent studies used a dynamic power-difference calorimeter.

  • Specific electrical resistance

A specially constructed experimental setup allows the measurement of the specific electrical resistance. On rod-shaped samples, the specific electrical resistance in a thermostatted bath at 20 ° C can be determined. To determine the temperature dependence, thin sample plates are used, in which antiparallel Sägeschnitte be introduced to increase the electrical resistance.

  • Thermal conductivity

Based on the law of Wiedemann-Franz-Lorenz, the thermal conductivity can be calculated, especially if one has derived the coefficients in the relationship of heat conductance and resistance measurements on samples of the steel to be examined with the same or similar composition.

  • Thermal conductivity

From the determined values ​​of thermal conductivity, true specific heat capacity and density, the numerical values ​​for the thermal diffusivity result. For the direct measurement, the laser flash method was used for some steels.
