METHOD OF DETERMINATION OF HEAT CAPACITY OF METALS AT DIFFERENT TEMPERATURES Russian patent published in 1995 - IPC

FIELD: testing of construction materials. SUBSTANCE: this method of determination of heat capacity of metals at different temperatures is based on data used for determination of state of tested metal (presence of dopes, impurities, defects of structure causing formation of internal stresses). In compliance with method plastically relaxed internal stresses are corrected by stabilization, elastic internal stresses are limited by their compensation by temperature stresses. Temperature dependence of heat capacity of metal presenting linear system has two linear sections in elastic regions separated by characteristic temperature. Heat capacity within intervals of constancy CT_c and decay CT_d is determined from equation CT_c=K_n·T+b_c, CT_d=K_d·T+b_d, where k and b are constants of straight line. EFFECT: enhanced efficiency of method. 2 cl, 2 dwg
