Deformed microstructures of two-phase Zr-2.5Nb alloy: Effects of the second phase hardness
Santosh K. Sahoo,V.D. Hiwarkar,L. Jain,Indradev Samajdar,Prita Pant,G.K. Dey,D. Srivastav,R. K. Tewari,Srikumar Banerjee +8 more
TL;DR: In this article, two types, A and B, of Zr-2.5Nb samples were subjected to compression tests and the relative hardness of β phase determined almost all aspects of deformed microstructure developments.
Journal ArticleDOI
Glass formation and crystallisation in rapidly solidified zirconium alloys
TL;DR: In this article, a comparison between the microstructures of binary and ternary metalloid free amorphous alloys rich in zirconium has been made in order to understand the process of solidification and phase selection.
Journal ArticleDOI
Grain fragmentation and twinning in deformed Zircaloy 2: Response to positron lifetime measurements
Santosh K. Sahoo,V.D. Hiwarkar,K.V. Mani Krishna,Indradev Samajdar,Prita Pant,P. K. Pujari,G.K. Dey,D. Srivastav,R. Tiwari,Srikumar Banerjee +9 more
TL;DR: In this article, the deformation twins, { 1 0 1 ¯ 2 } 〈 1 ¯ 0 1 1 1 〉 type tensile twins, were identified from axis-angle relationship: 94.8° ˈ 1¯ 2 1¯ 0 ˉ, a deviation of more than 5° from the exact twin orientation relationship was considered as annihilation.
Journal ArticleDOI
A study on microstructure, magnetic properties and kinetics of the nanocrystallization of Fe40Ni38B18Mo4 metglass
TL;DR: In this article, the microstructure and magnetic properties of Fe40Ni38B18Mo4 at various degrees of crystallization from the amorphous state were investigated and the growth behavior and morphology of the nanocrystalline phases have been studied as a function of time and temperature.
Journal ArticleDOI
Through-Thickness Deformation Gradient in a Part-Pilgered Zirconium Tube: Experimental Measurements and Numerical Validation
Gulshan Kumar,Sandip Balo,Ashish Dhoble,Jaiveer Singh,Ramesh Singh,Deepali Srivastava,G.K. Dey,Indradev Samajdar +7 more
TL;DR: In this article, through-thickness microstructure development and residual stress evolution were explored in a part-pilgered Zircaloy-4 tube and the deformation gradients were also simulated with a three-dimensional elastoplastic finite element model.
