研究了Nd和V共取代钛酸铋陶瓷（Bi4-y,Ndy）1-(x/12)(Ti3-x,Vx)O12 [BNTV-y (x=0.01, y=0.00~1.00)]的压电性能。采用热锻法研究了晶粒取向对BNTV-y陶瓷压电性能的影响。普通烧结（of） BNTV-y0.75陶瓷的机电耦合系数k33为0.21，是铋层结构铁电体（BLSFs）中k33值最高的陶瓷之一。而晶粒取向（HF） BNTV-y0.25陶瓷的k33为0.30。
The piezoelectric properties of Nd and V cosubstituted bismuth titanate ceramics, (Bi4-y,Ndy)1-(x/12)(Ti3-x,Vx)O12 [BNTV-y (x=0.01, y=0.00~1.00)] , are investigated. Furthermore, the grain orientation effects of BNTV-y ceramics on their piezoelectric properties are studied by the hot forging (HF) method. The electromechanical coupling factor, k33, of ordinarily fired (OF) BNTV-y0.75 ceramic was 0.21, which is one of the highest k33 values for bismuth layer-structured ferroelectrics (BLSFs). On the other hand, the k33 of the grain oriented (HF) BNTV-y0.25 ceramic was 0.30.
