Effect of Fe addition on the microstructure, transformation behaviour and superelasticity of NiTi alloys fabricated by laser powder bed fusion

open access: yesVirtual and Physical Prototyping, 2023
NiTi-Fe ternary shape memory alloys were produced by laser powder bed fusion (L-PBF) using the pre-alloyed NiTi and elemental Fe powders. A large process window exists to fabricate dense NiTiFe0.3 and NiTiFe0.5 alloys, while severe cracks occur in the ...

Uprighting Mandibular Third Molar Using NiTi Wire [PDF]

open access: yesDental Journal of Advance Studies
If impacted teeth can be brought into occlusion, they should be brought into occlusion, especially in young patients. When the second molar is missing, saving the third molar becomes all the more important.
