Capsule-free hot isostatic pressing of sintered steel to full density using water atomised iron and Cr-alloyed powder consolidated by cold isostatic pressing
Autor: Eduard Hryha, Lars Nyborg, Ola Bergman, Sigurd Berg, Maheswaran Vattur Sundaram, Magnus Ahlfors
Publikováno v: Powder Metallurgy. 65:133-140
Powder metallurgy (PM) steel with enhanced density is essential for meeting the demands on high strength and high-performance applications. In this study, cold isostatic pressing (CIP) is applied for consolidating water-atomised iron and Cr-alloyed s
