HI, You had better to use SiO2 or Si3N4 instead of Si. Forming SiNi is your problem since the silicide is brittle. The SiO2(i.e. Thermal) can protect from forming silicide for crystalization of NiTi. This is just one possibility. Good luck. ============================================ Kiyotaka Mori (Graduate Student) Dept.of Materials and Nuclear Engineering, BLDG.090, University of Maryland at College Park, College Park, MD 20742 Tel: 301-405-5229 Fax: 301-314-9467 E-mail: mori@eng.umd.edu ============================================ Home: 9336 Cherry Hill Rd, #101, College Park, MD 20740 Tel: 301-345-2012 Fax: 301-345-2012 ============================================ Every obstacle is a stepping stone to your success.
