Isothermal Calorimetric Investigation of a Reversible Reaction in Rapidly Solidified Fe sub 40 Ni sub 40 B sub 20

摘要

A new method is described for isothermal calorimetric measurement of time-dependent reversible reactions in which the rate of heat flow is small compared to the noise and zero drift of the measurement. Results using this method are presented which measure enthalpy changes associated with reversible phase changes in a rapidly solidified Fe sub 40 Ni sub 40 B sub 20 alloy. (ERA citation 09:016893)
