Heat Transfer Coefficient for Cooling Solder
Heat Transfer Coefficient for Cooling Solder
(OP)
I'm doing some testing on Pb-Sn 50-50 Solder. When the solder was cooled from 360C to 60C, my data showed a wide range of combined heat transfer coefficients. Should this value remain constant throughout cooling?

A change of phase occurring, see the phase diagram at http://cyberbuzz.gatech.edu/asm_tms/phase_diagrams/pd/Pb_Sn.GIF
