Adaptive Thermal Analysis System

A T A S Pearlite

Thermal Analysis System for estimation of

Pearlite, Brinell Hardness and Tensile

slide3

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.

slide4

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
slide6

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

slide7

All results can be displayed in the SPC chart

Note the time stamp for each sample.

slide10

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