These materials were diffusion bonded at 1200°C for one hour under 20 MPa in a vacuum of 2.1�10-6 Torr. The microstructural analyses showed that joining sialon to nitrided steel produced thinner reaction layers and no gap or crack were formed on the sample. Gaps were produced in joining sialon to as-received steel. From the elemental analyses, alumina and iron silicides were formed at the interface layer of sialon/as-received steel joint. Alumina and smaller amount of silicides were detected at the interface layer of sialon/nitrided steel joint. Diffusion layer and parent steel of the sialon/nitrided steel joining contained nitrides. The hardness test across the joints indicated that reaction layers possessed intermediate hardness between sialon and steel. The layers contributed to ductility of the joint that help to attain the joint. © (2014) Trans Tech Publications, Switzerland. date: 2014 publisher: Trans Tech Publications Ltd official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-84904118969&doi=10.4028%2fwww.scientific.net%2fAMR.974.199&partnerID=40&md5=c31e0cfce21c9db63063be2fd3b23346 id_number: 10.4028/www.scientific.net/AMR.974.199 full_text_status: none publication: Advanced Materials Research volume: 974 place_of_pub: Kuala Lumpur pagerange: 199-204 refereed: TRUE isbn: 9783038351498 issn: 10226680 citation: Ibrahim, N.N.M. and Hussain, P. and Awang, M.
