Transition of deformation behavior in an ultrafine grained magnesium alloy
Sushanta Kumar Panigrahi,K Kumar,Nilesh Kumar,Wei Yuan,Rajiv S. Mishra,R. DeLorme,B. Davis,R.A. Howell,Kyu Cho +8 more
TL;DR: In this article, the deformation behavior of friction stir processed magnesium alloy with average grain size ranging from 25μm to 240nm was studied and critical grain size for transition of deformation mode from twinning to slip was carried out by employing tensile and compressive tests.
Journal ArticleDOI
Influence of SiC ceramic reinforcement size in establishing wear mechanisms and wear maps of ultrafine grained AA6063 composites
TL;DR: In this paper, the influence of varying sizes of SiC ceramic reinforcement (coarse (12μm), fine (1μm) and nano (45 nm) in establishing the wear mechanisms and the wear mechanism maps of ultrafine grained (UFG) AA6063/4 wt%SiC composites was described.
Journal ArticleDOI
Influence of annealing on stain hardening behaviour and fracture properties of a cryorolled Al 2014 alloy
TL;DR: In this paper, the influence of annealing on strength, ductility, strain hardening, plastic instability and fracture behaviour are studied in the present work on a cryorolled Al 2014 alloy by tensile test, transmission electron microscopy, macrograph analysis and fractography study.
Journal ArticleDOI
Achieving excellent thermal stability and very high activation energy in an ultrafine-grained magnesium silver rare earth alloy prepared by friction stir processing
F. Khan,Sushanta Kumar Panigrahi +1 more
TL;DR: In this article, an ultrafine-grained microstructure of a QE22 alloy prepared by Friction Stir Processing (FSP) is isochronally annealed to study the thermal stability and grain growth kinetics.
Journal ArticleDOI
A study on the combined effect of in-situ (TiC-TiB 2 ) reinforcement and aging treatment on the yield asymmetry of magnesium matrix composite
TL;DR: In this paper, the effect of in-situ particles and precipitates on the tension-compression asymmetricity of AZ91 magnesium (Mg) alloy and AZ91+TiC-TiB2 Mg matrix composites was investigated.
