Abstract
Warm equal channel angular extrusion is used to consolidate a blend of amorphous Hf44.5Cu27Ni13.5Ti5Al10 and crystalline W powders. Dissolution of the W phase results in ∼60% aligned, elongated pores within an amorphous Hf-based matrix exhibiting ductility in compression, but at lower strengths than similar amorphous Zr-based foams due to incomplete bonding between Hf-based powders.
► Hf-based bulk metallic glass foams with aligned, elongated pores. ► Warm equal channel angular extrusion used to consolidate amorphous Hf-based powders and crystalline W space holders. ► Lower strengths than expected due to incomplete bonding of BMG powders.
