Heat Treatment

Whether microstructure, structural state, or mechanical behaviour – heat treatment is critical to understanding materials. With our expertise and modern equipment, we support you in the targeted adjustment, simulation, and analysis of heat treatment conditions. This creates a solid basis for meaningful materials investigations – reproducible, traceable, and tailored to your specific questions.

Our Services at a Glance

  • Vacuum and protective gas heat treatments – hardening, annealing, tempering, etc., on specimens, components, small series, and sample batches

  • Inductive heat treatment – development of induction heat treatment processes on bar material

  • TTT / CCT diagram generation (ZTU / ZTA) – customer-specific determination of transformation diagrams for steels

  • B-H curve measurement – frequency- and amplitude-dependent recording of material-specific B-H curves

Your Benefits

  • Fast and reliable heat treatment for specimens, individual parts, and sample batches – high flexibility for small series
  • Tailor-made processes for fast, local, and highly reproducible heating of bar material
  • Robust data on the transformation behaviour of your steels for safe and effective heat treatment
  • Precise, frequency-dependent measurement data to design efficient inductors and electric motors

Our Services in Detail

Vacuum and Protective Gas Heat Treatment

Vacuum and Protective Gas Heat Treatment

  • Custom, instrumented heat treatment processes under (convective) vacuum

  • Temperature-controlled heat treatment of specimens and components including controlled quenching (l_min = 0.2)

  • Tempering or annealing under (convective) vacuum, protective gas (Ar, N₂), or atmospheric conditions

Inductive Heat Treatment

Inductive Heat Treatment

  • Instrumented induction heat treatment with water or gas quenching for process development

  • Simulation of temperature, microstructure, and residual stress distributions and their evolution during induction heat treatment

TTT / CCT Diagrams (ZTU / ZTA)

TTT / CCT Diagrams (ZTU / ZTA)

  • Investigation of steels, in particular highly alloyed, multiphase stainless steels

  • Physical simulation of heat treatment processes using a quenching dilatometer

  • Determination of time–temperature–transformation (TTT) diagrams and time–temperature–austenitising (TTA) diagrams

B-H Curve Measurement

B-H Curve Measurement

  • Robust material selection: precise, material-specific data on magnetic permeability and magnetisation losses (core losses)

  • Optimisation of electromagnetic components: enables accurate simulation and design of inductors, transformers, and electric motors to maximise efficiency and performance

  • Loss minimisation: knowledge of frequency- and amplitude-dependent losses (B-H curves) supports the selection of optimal materials for energy-efficient applications
