Volume 8, Issue 9 , September 2017, , Pages 897-904


  Mg22Gd alloy was processed by high pressure torsion (HPT) at room temperature and the pressure of 2 GPa. A series of specimens with different number of rotations N (N = 0-15) was prepared from the initial coarse grained as cast material. Mechanical properties were investigated by microhardness mapping. ...  Read More

High Temperature Dielectric Relaxation And Impedance Spectroscopy Studies On BaBiO3 

Divyanshu Bhatnagar; Ratnamala Chatterjee

Volume 7, Issue 8 , August 2016, , Pages 604-609


  BaBiO3 (BBO) particles were successfully synthesized through solid-state route, to provide better understanding of its transport properties, which is not well studied yet. X-ray diffraction (XRD) measurement confirmed that the particles were crystallized with monoclinic structure in single phase. The ...  Read More
