The present paper thus involves study of the austenitization temperature effects and holding times at these temperatures with subsequent forming of materials, straining in intercritical region and rapid cooling down to the area of bainite nose and holding at this temperature.
The objective of this paper is to identify optimum forming conditions with subsequent controlled cooling or optimum conditions of separate heat treatment to achieve a high ductility of materials.

The optimized annealing conditions (950°C for 15 min) give the following results: εr = 780 and tgδ = 0.01 at 100 kHz, Pr = 13 µC/cm², Ec = 63 kV/cm and a tunability of 55%. 1 Introduction Piezoelectric actuators, infrared sensors, FeRAM usually contain lead based materials [1-2].
Among these materials, PbZrTiO3 (PZT) is the most used thanks to its superior piezoelectric performances.
Accordingly, it is now necessary to implement materials without prohibited substances.

Due to normal growth, which requires additional material, the lateral propagation rate in uncovered films becomes lower compared to that in the covered films where normal growth is absent. 05 10 15 20 25 0 0.5 1 1.5 2 2.5 t1/2 (h1/2 ) xA1 ( m) H=90 nm; a=18 nm H=90 nm; a=40 nm H=50 nm; a=18 nm H=180 nm; a=18 nm 1 2 m) 0 5 10 15 20 25 30 35 40 0 0.5 1 1.5 2 2.5 t 1/2 (h 1/2) xA2 ( m) H=90 nm; a=18 nm H=90 nm; a=40 nm H=50 nm; a=18 nm H=180 nm; a=18nm 2 1 m) Fig. 4.
Specific feature of nano-grained materials consists in small length of the B-zone in comparison with the zone A: the smaller grain size, the shorter is the B-zone.

Combining the numerical simulations and calibration on realistic materials, the plastic work can be estimated and the irreversible work can be easily calculated from the load-displacement curve.
The interfacial toughness can be estimated by treating the interface as a homogeneous material with the Young's modulus and hardness as composite parameters of the coating and substrate so that linear fracture mechanics for brittle materials can be applied.
Marshall et al [43] proposed a model to relate the toughness of brittle bulk materials to the depth where lateral cracks occur and the crack driving force Pr due to the residual stress during unloading.
