Actually, bio oil contains many compounds, such as hydroxyl acetone, furfural, phenols, levoglucosan, etc., some of which are the important intermediate product for food, medicine or the other materials.
In order to obtain advantage materials, people have tried many approaches to transform the bio mass into some certain species, which are mainly phenols and carbon acids [2-4].

Introduction Ferroelectric materials have received an increasing number of attention in smart functional materials due to microminiaturization, low energy consumption and high response velocity[1-5].
In fact, ferroelectric materials exhibit strong nonlinear response under a large mechanical and electrical loading.
The materials parameters of the PbTiO3 are listed in Table 1.

MAUD software (Materials Analysis Using Diffraction) was used to analyze the microstructural parameters and dislocation density.
The WAAM uses various materials, such as titanium alloys, aluminum alloys and stainless steels [3].
According to Bronkhorst et al. (2019) [7], the initial dislocation density in AM materials is around three times higher than in forged materials.
