Abstract[001]C‐Textured 0.55Pb(Ni1/3Nb2/3)O3–0.15PbZrO3–0.3PbTiO3 (PNN‐PZT) ceramics are prepared by the templated grain‐growth method using BaTiO3 (BT) platelet templates. Samples with different template contents are fabricated and compared in terms of texture fraction, microstructure, and piezoelectric, ferroelectric and dielectric properties. High piezoelectric performance (d33 = 1210 pC N−1, d33* = 1773 pm V−1 at 5 kV cm−1) and high figure of merit g33⋅d33 (21.92 × 10−12 m2 N−1) are achieved in the [001]C‐textured PNN‐PZT ceramic with 2 vol% BaTiO3 template, for which the texture fraction is 82%. In addition, domain structures of textured PNN‐PZT ceramics are observed and analyzed, which provide clues to the origin of the giant piezoelectric and electromechanical coupling properties of PNN‐PZT ceramics.

Polycrystalline Fe 2 AlB 2 bulk including minor Al 2 O 3 is synthesized by reactive hot pressing from Fe, Al, and B powders at 1200°C and 30 MPa for 30 minutes, with a relative density of 96%. The present approach enables a markedly reduced holding time compared with previous studies. The derived Fe 2 AlB 2 shows an electrical resistivity of 2.27AE0.01 lΩÁm, Vickers hardness of 10.2AE0.2 GPa, flexural strength of 232AE25 MPa, compressive strength of 2101AE202 MPa, fracture toughness of 5.4AE0.2 MPaÁm 1/2 and work of fracture of 117AE12 J/m 2 . No dominant indentation cracks are observed, indicating that Fe 2 AlB 2 may be quite damage tolerant. Interestingly, a noncatastrophic failure is present in the SENB test, with a high work of fracture. The energy-absorbing mechanisms in inhibiting crack formation are delamination and pullout of Fe 2 AlB 2 grains. K E Y W O R D S borides, electrical conductivity, hot pressing, mechanical properties
