  1. Adaptive Thermal Analysis System A T A S Pearlite Thermal Analysis System for estimation of Pearlite, Brinell Hardness and Tensile ATAS is a registered trademark of NovaCast AB - Ronneby - Sweden

  2. The Eutectoid Reaction determines % Pearlite and BHN

  3. The eutectoid reaction occurs after 8 to 10 minutes. It is sensitive to several elements such as Si, Cr, Cu, Mn etc. The released latent heat allows an accurate prediction using the ATAS Pearlite system.

  4. ATAS Hardware • PC, min 1GHz, 256 MB RAM • A/D converter • UPS, back-up power source • Cup holder • Ventilated casing • Suitable for all ATAS products

  5. The ATAS Pearlite system is very easy to use - Just pour a sample - The rest is automatic!

  6. The sample is automatically evaluated and all data saved. The system is reset if the used test-cup is replaced.

  7. All results can be displayed in the SPC chart Note the time stamp for each sample.

  8. The general settings are made in this screen

  9. The channel specific parameters are set in this screen

  10. The Alloy database allows the foundry to enter their own alloys and calibrate each one for maximum accuracy.

  11. ATAS Pearlite uses the standard method, which is linear regression

  12. Prediction of % Pearlite with ATAS Pearlite Actual data from a US Ductile Iron Foundry

  13. Prediction of BHN with ATAS Pearlite Actual data from a US Ductile Iron Foundry

  14. Why ATAS Pearlite? • Automatic evaluation • Consistent results • Quality Assurance test • Eutectoid transformation sensible to changes of critical elements • Allows savings of Cu additions and manhours! ATAS Pearlite for efficient Metallurgical Process Control

  15. ATAS - Optional modules • ATAS Verifier - The main TA system • Pearlite, Hardness & Tensile Prediction • Nodularity & Nodule Count • Dynamic inoculation • NovaCast also offers consultancy! ATAS is a registered trademark by NovaCast AB - Ronneby - Sweden
