In a complex state of stress is the materials of equipment in engineering applications, domestic and overseas researchers have been trying to obtain the material properties of the plastic deformation and ultimate strain under different stress states through a variety of means[3-5].
In order to be close to the authenticity of the materials, the true stress - true strain calculation method was taken.

Introduction Hematite (α-Fe2O3) have attracted much attention because of their potential applications in photocatalysts and other electronic materials based on their distinct characteristics.
The reason for this phenomenon has been already reported as the disorder of the crystal structure which was induced by the dopants materials.
Through this work, we introduced a new insight for application of transition metal doped hematite nanocrystal for the enhanced properties of photocatalysts and magnetic materials.

Dwivedi2b 1,2Department of Physics and Materials Science and Engineering, Jaypee Institute of Information Technology, Noida - 201307 (India) avijayetapal@gmail.com, brk.dwivedi@jiit.ac.in Keywords: Lead free piezoelectric, XRD, Dielectric, Ferroelectric, Bi0.5Na0.5TiO3 Abstract Piezoelectric materials have wide applications in today’s advanced technologies.
Introduction In the last few years, lead free piezoelectric materials are rapidly gaining interest amongst research groups as the environment concerns regarding the disposal of toxic materials.
European regulations now exclude the use of most lead containing materials in electronic and electrical devices.
Like several other lead free materials as BaTiO3, Bi0.5Na0.5TiO3 (BNT) was first reported in the 1960’s by Smolenskii et. al [3] but did not receive much attention until the recent surge in lead free materials development in the past few years.

The problem is aggravated by the general decrease in quality of oil road bitumens made in Russia, absence in many regions of standard mineral raw materials, and also a wide range of climatic conditions.
Now the branch of nanotechnologies provides a wide range of modifiers and ways of modification for improvement of quality of composite materials in the set direction [1-3].
Research As objects of research the following porous fillers were chosen: expanded clay, perlite, the zeolite different from traditional raw materials by increased porosity.
However these raw materials have a number of features which technologically complicate its application.
