SPHERICAL SAMPLES

UDC 536.2.083

Consideration is given to a version of the pulse method 
of measurement of the thermal diffusivity of spherical samples with 
the use of laser heating. The method is based on solution of 
the heat-conduction equation in a spherical coordinate system. 
The computerized experimental setup used is described. Measurement 
results for the thermal diffusivity of Zr, Ni, Fe, Al are reported. 
The measurement error is no more than 5%.
