As far as gold embrittlement and gold diffusion, you had better read Z. Mei's
paper given at the SMTA conference in late August 98. He indicated in his
research that gold may migrate back to the joint interface after aging for a
length of time at somewhat elevated temperatures. Us who deal in metallurgical
reactions were amazed, but look at his research. The paper is in the
proceedings.
