Development of a novel ZrO2 dispersion strengthened 9Cr ferritic steel: Characterization of milled powder and subsequent annealing behavior

Raghavendra, K.G.; Dasgupta, A.; Ghosh, C.; Jayasankar, K.; Srihari, V.; Saroja, S. (Powder Technology, 327, 2018: 267-274)

A novel ODS ferritic steel with ZrO2 dispersoids is developed as a candidate structural material for future fast reactor applications. Encouraged by our earlier results demonstrating the retention of crystallinity by ZrO2 ...
Microstructural Evolution of Nanocrystalline ZrO2 in a Fe Matrix During High-Temperature Exposure

Raghavendra, K.G.; Dasgupta, A.; Athreya, C.N.; Jayasankar, K.; Saroja, S.; Sarma, V.S. (Metallurgical And Materials Transactions A-Physical Metallurgy And Materials Science, 49a(8), 2018: 3565-3574)

The current study examines the evolution of nanocrystallites of ZrO2 with time and temperature in a Fe-ZrO2 composite. The crystallite sizes were determined through X-ray peak broadening analysis by the Williamson-Hall ...
Structural Studies of Dispersoids in Fe-15 wt% Y2O3-5 wt% Ti Model ODS Alloys During Milling and Subsequent Annealing

Parida, P.K.; Dasgupta, A.; Raghavendra, K.G.; Jayasankar, K.; Saroja, S. (Transactions Of The Indian Institute Of Metals, 70(6), 2017: 1409-1415)

Oxide dispersion strengthened (ODS) steels have very high thermal stability and creep resistance due to reinforcement of hard and stable nano-sized ceramic dispersoids in metallic matrix which act as barriers to dislocation ...
Synthesis and characterization of Fe-15 wt.% ZrO2 nanocomposite powders by mechanical milling

Raghavendra, K.G.; Dasgupta, A.; Bhaskar, P.; Jayasankar, K.; Athreya, C.N.; Panda, P.; Saroja, S.; Sarma, V.S.; Ramaseshan, R. (Powder Technology, 287, 2016: 190-200)

Fe-15 wt.% ZrO2 nanocomposite powder was synthesized via mechanical milling with an aim to study the morphology of the powder particles and refinement of the oxide and Fe crystallites during milling. Detailed microstructural ...
Thermal evolution of Fe - ZrO2 nanocomposite: Insights from calorimetric and microscopy investigations

Raghavendra, K.G.; Dasgupta, A.; Hajra, R.N.; Jayasankar, K.; Srihari, V.; Saroja, S. (Materials Characterization, 132, 2017: 448-457)

This article presents the results of an experimental study on the evolution of phases during annealing of ball milled Fe ZrO2 nanocomposite powder using Differential Scanning Calorimetry, X-ray Diffraction and Electron ...
