Webinar: Binder Jetting Hard-to-Weld, Nickel-Based Superalloy RENÉ 108
Binder Jetting Hard-to-Weld, Nickel-Based Superalloy RENÉ 108
The ultra-high strength of nickel-based superalloys with low ductility comes with the price of high susceptibility to cracking and a high residual stress state when processed with conventional powder bed fusion technologies. Binder Jet additive manufacturing is an interesting alternative to other additive manufacturing (AM) modalities, since it does not require melting to fuse powder material but selectively adheres powder with a binder. While there are several studies on the use of melting and other solidification-based AM technologies for nickel-based superalloys, limited literature is available on the use of Binder Jet for these materials.
This webinar looks at the advantages and disadvantages associated with using Binder Jet with RENÉ 108 as an example superalloy. Based on the study done by GE Additive, 'Ecole Polytechnique and GE Power, this session will examine the effects on the green, brown and sintered states of the part, looking at mechanical properties and deformation at all stages and applications related to Ni alloys.
