casting process of single crystal nickel base superalloy



Where can I found more information about the casting process of single
crystal nickel base superalloy for turbine blades (jet-engine)?
I found only this website:
http://www.msm.cam.ac.uk/phase-trans/2003/Superalloys/superalloys.html
Is there any other website and/or book?
Thanks.
