U-SANS analysis of as-sintered and PEC-treated NiTi SMA produced by metal injection moulding

  • Published:
Strength of Materials Aims and scope

Using ultra-small angle neutron scattering method, we have analyzed sizes of pores of 100 nm–25 μm in diameter in specimens from NiTi shape memory alloys produced by metal injection moulding before and after pulse electric current treatment. Such treatment invokes coalescence of pores with diameter smaller than 4 μm and size reduction of pores with diameter exceeding 4 μm.
