Patent ID: 8126657

Claim:
A method of predicting IT and FT values from measured ST and HT temperatures of a specimen by applying a multi-linear regression analysis to measured ST and HT temperatures utilizing a microprocessor, wherein IT and FT values from measured ST and HT temperatures of a specimen are computed by a computer programmed to apply the following formulae: For reducing atmospheres: IT=C 1 ×ST−C 2 ×HT+C 3 FT=C 4 ×HT−C 5 ×ST+C 6 For oxidizing atmospheres: IT=C 7 ×ST−C 8 ×HT+C 9 FT=C 10 ×HT−C 11 ×ST+C 12 Where: IT is the initial deformation temperature; ST is the softening temperature; HT is the hemispherical temperature; FT is the fluid temperature; and C 1 -C 12 are constants determined by multi-linear regression coefficient analytical techniques on the collection of data.
