Abstract
Compositional varieties of alpha-SiAlON a yttrium stabilized solid solution of alpha-Si3N4, were studied against 304L stainless steel through interacting couples prepared under hot pressing (1100-1300 degrees C, 1.8 MPa, 5 h) with respect to their chemical interactions and interface bonding formation. Interdiffusion of elements in both ceramic and steel side followed by the series of reactions those produced the interfaces between the joints were seen. Chemical behaviour of alpha' vis-a-vis its compositional nitrogen content has been discussed. (c) 2010 Published by Elsevier Ltd and Techna Group S.r.l.
