Heat Treatments

Founded in 1968, the Heat Treatment Lab of Centro Sviluppo Materiali S.p.A. may be considered as the starting point for all the developments carried out on alloys research for what regards chemical and physical metallurgy of materials and processes.


This capability is jointly delivered by the Rome Headquarter and Terni Branch Office.
The set of furnaces deployed in the laboratory placed in Rome allows the selection of the temperature-time cycles able to maximize the mechanical features of the material and give them the best microstructure so steering the process towards solutions guaranteeing the highest possible performance for the material.
The Lab is equipped with six muffle furnaces; two of them can reach the maximum temperature of 1300 °C allowed by two silicon carbide heating elements. The remaining four furnaces temperature may reach 1050°C. Their heating-up speed ranges in between 200¸300 °C/h, whereas the closed-furnace cooling-down velocity falls within 60 ¸ 80°C/h.
The Lab is equipped with facilities to carry out water, waterquench and oil quench treatments, followed by forced air cooling on small-sized samples if reuired.
The temperature evolution is collected by thermocouples. At the moment the temperature trends are recorded on paper sheets: future implementations of the acquisition system will allow the electronic treatment of the signals by means of a 4-channel data-logger.
The following devices are available in the lab of Rome:
  • an Infrared Rays heated furnace (Data-Trak) equipped with a quarz 50 mm chamber, allowing to set up a controlled atmosphere for small size samples;
  • an apparatus designed to simulate the welding cycles (SMITWELD) and the impact of the process on micostructures;
  • two dilatometers (THETA and ADAMEL) also permitting the determination of critical temperatures;
  • One Wolpert durometer.
The lab located in Terni is endowed with:
  • six heat furnaces with circular section cameras (85-100 mm diameter for five units, and 200 mm diameter for one unit). They can operate in controlled atmospheres (usually composed of N2, H2, He, Ar and NH3). Some of them can also control the humidity level and the ammonia atmosphere to simulate nitriding surface tratment processes. Three of them can be set at a maximum temperature value of 1200°C. The medium sample size is 80*300*2 mm (for flat samples) and the samples dimension can be changed in order to take into account the the camera stable thermal zone;
  • a pilot line for the continuous heat treatmets of 110÷120 mm large and 0.20÷0.50 mm thick flat sheets consisting of:

- one degreasing section;

- a high-powered induction heating station capable of an heating speed between 500 ÷ 1000°C/sa long furnace with a maximum temperature of 950°C which is composed of several thermically different and possibly managed simultaneously at different atmospheres (N2, H2, He, Ar and NH3) sections.

- one cooling section adopting liquid and gas jet coolers;

-one deposition section;

- one drying furnace.
