Kinetics of thermal decomposition of hydrated minerals associated with hematite ore in a fluidized bed reactor

Beuria, P.C.; Biswal, S.K.; Mishra, B.K.; Roy, G.G. (International Journal Of Minerals Metallurgy And Materials, 24(3), 2017: 229-239)

The kinetics of removal of loss on ignition (LOI) by thermal decomposition of hydrated minerals present in natural iron ores (i.e., kaolinite, gibbsite, and goethite) was investigated in a laboratory-scale vertical fluidized ...
Nanofiltration for textile dye-water treatment: Experimental and parameter estimation studies using a spiral wound module and validation of the Spiegler-Kedem-based model

Dash, B.; Kumar, A. (Separation Science And Technology, 52(7), 2017: 1216-1224)

The present work deals with the study of the nanofiltration process for textile dye wastewater treatment. Effects of feed pressure, dye concentration, and feed flow rate on dye rejection and recovery for the spiral wound ...
Thermal stability studies of tungsten nitride thin films

Anwar, Sharmistha; Anwar, Shahid (Surface Engineering, 33(4), 2017: 276-281)

Superior mechanical properties, such as hardness of high level along with thermal stability are of great technological interests for cutting tools and other industrial applications. In this work, we present performance and ...
Synergetic Surface and Chemical Durability Study of the Aesthetically Enhanced Natural Quartz by Heat Treatment

Sahoo, R.K.; Rout, P.P.; Singh, S.K.; Mishra, B.K.; Mohapatra, B.K. (Metallurgical And Materials Transactions A-Physical Metallurgy And Materials Science, 48A(3), 2017: 1111-1120)

The change in surface behavior of natural quartz stone before and after heat treatment with metal oxides such as: cobalt oxide (Co3O4) and copper oxide (Cu2O) under vacuum and open atmosphere has been investigated. The ...
Effect of Cooling Rate and Chemical Composition on Microstructure and Properties of Naturally Cooled Vanadium-Microalloyed Steels

Karmakar, A.; Sahu, P.; Neogy, S.; Chakrabarti, D.; Mitra, R.; Mukherjee, S.; Kundu, S. (Metallurgical And Materials Transactions A-Physical Metallurgy And Materials Science, 48A(4), 2017: 1581-1595)

Samples from two V-microalloyed steels (0.05 wt pct V) having different C and N levels, namely high-C low-N steel, HCLN (0.22 wt pct C, 0.007 wt pct N) and low-C high-N steel, LCHN (0.06 wt pct C, 0.013 wt pct N) were ...
Preparation of light weight constructional materials from chrome containing buffing dust solid waste generated in leather industry

Sivaprakash, K.; Maharaja, P.; Pavithra, S.; Boopathy, R.; Sekaran, G. (Journal Of Material Cycles And Waste Management, 19(2), 2017: 928-938)

An alternative and environmentally benign method of disposing the buffing dust, generated from leather industry was carried out in the present investigation. The buffing dust (finished solid waste) was charred in a controlled ...
Short-term leaching study of heavy metals from LD slag of important steel industries in Eastern India

Chand, S.; Paul, B.; Kumar, M. (Journal Of Material Cycles And Waste Management, 19(2), 2017: 851-862)

Considering Linz-Donawitz (LD) slag as a waste material for its bulk utilisation, there is a possibility that heavy metals will leach to environment. It necessitates the study on physical, chemical, mineralogical and heavy ...
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 ...
Electrochemical Fencing of Cr(VI) from Industrial Wastes to Mitigate Ground Water Contamination

Shukla, N.; Harbola, M.K.; Sanjay, K.; Shekhar, R. (Transactions Of The Indian Institute Of Metals, 70(2), 2017: 511-518)

Indiscriminate dumping of solid industrial wastes and the consequent ground water contamination by heavy metals such as Cr(VI) is a major environmental concern. Electrochemical fencing, an extension of electroremediation, ...
Study of Temperature Profile in the Induration of Magnetite Iron Ore Pellets

Prusti, P.; Nayak, B.K.; Biswal, S.K. (Transactions Of The Indian Institute Of Metals, 70(2), 2017: 453-462)

The pelletisation study of magnetite iron ore fines starts with green balling using limestone and bentonite as additives. Heating cycle of iron ore pellets is one of the prime segments of the whole pelletisation process. ...
