摘要：the invention concerns a method for thermomechanical analysis of a sample (p)of a material (a)) of the full sample (p) in a thermomechanical analyseeinrichtung (10) andtemperature control of the sample (p) by means of the analyseeinrichtung according to amodulated temperaturprogrammes, (b) recording by means of the analyseeinrichtung

derived datathe representative of an elongation (dl) of the sample (p) in the course ofthe temperature control units, (c) evaluating the data, a reversible component (dlrev)elongation (dl) and \\/ or a reversible component (\αrev) of the thermal coefficient ofexpansion (a) of the sample (p) to identify tteln,(d) to calculate a corrected reversiblecomponent (dlrev corr; \αrev corr) elongation (dl) and \\/ or the thermal coefficientof expansion (a) by means of a korrekturparameters (k)the using of the data identified atotal elongation ratio (dltotal) and parameter (\αtotal) and a reversible component(dlrev) elongation (dl) and parameter (\αrev) is

calculated.erfindungsgem\ä\ß has the temperaturprogramm a first segment(s1) with a first basisheizrate (\β1) and the korrekturparameter (k) on the basis ofdata from the first segment (s1) to estimate a temperature from a temperaturedependent function of the relationship. n a field of the first segment (s1) calculatesinwhich the sample (p), a thermally induced transformation is, with the

temperaturprogramm a second segment (s2) with a e.g.compared with the first

basisheizrate (\β1) smaller second basisheizrate (\β2) owns and for calculationof the corrected reversible component (dlrev corr; \αrev corr) elongation (dl) and \\/or the thermal coefficient of expansion (a) in the second segment (s2) on the basis of thed data from the first segment (s1) calculated korrekturparameter (k) is used.
