Experimental research on mechanism and process of direct iron making reduction of mechanically milling scale with coal
(Elsevier Science Sa, 2015)
This study delved into the fundamental mechanisms of a mill scale reduction. To achieve this objective, the DRI process was applied to facilitate the mechanical milling of coal-scale mixtures. Temperatures of 700-1000 ...
Wear behavior of iron boride coating on AISI 4140
(Maik Nauka/Interperiodica/Springer, 2016)
A new paste technique was established for making boronising coatings. This method gave iron boride coatings a unique wear and tear property something that was tested as a microstructural feature. The coats were acquired ...
Effect of TiBAl inoculation and heat treatment on microstructure and mechanical properties of hypereutectic high chromium white cast iron
(Elsevier Science Sa, 2016)
Hypereutectic high chromium white cast iron alloys were produced with TiBAl (1-3 wt.%) inoculants. The heat treatments were applied to the samples as 1000 degrees C for 1 and 2 h. The microstructures of the samples were ...
Effect of mechanical alloying on FeCrC reinforced Ni alloys
(Carl Hanser Verlag, 2016)
Mechanical alloying (MA) is a powder metallurgy processing technique involving cold welding, fracturing and rewelding of powder particles in a high-energy ball mill. In the present study, the intermetallic matrix composites ...
Sliding wear behavior of FeCrC reinforced and Ni-based composites produced by mechanical alloying technique
(Redakcia Kovove Materialy, 2018)
The study presents the behavior of FeCrC particulates reinforced and Ni-based composites produced by a mechanical alloying process in the presence of friction and wear. Ni, Al and M7C3 powders having 100 mu m size were ...
Effect of TiBAl inoculation on abrasive wear resistance of high Cr white cast iron
(Carl Hanser Verlag, 2019)
High chromium white cast iron (HCrWCI) is generally used in applications requiring superior wear resistance. The alloys were inoculated with 1-3 wt.-% TiBAl to rearrange the crystallography of the carbides. The alloys were ...
MICROSTRUCTURE AND WEAR PROPERTIES OF FeCrC, FeW AND FeTi MODIFIED IRON BASED ALLOY COATING DEPOSITED BY PTA PROCESS ON AISI 430 STEEL
(Polska Akad Nauk, Polish Acad Sciences, Inst Metall & Mater Sci Pas, 2014)
The plasma transferred arc (PTA) process was used for developing wear resistance of AISI 430 steel substrate. Appropriate quantities of FeCrC, FeW and FeTi powders were combined to create conditions that synthesized M7C3 ...
Effect of different rotational speeds on mechanical and metallurgical properties of friction welded dissimilar steels
(Carl Hanser Verlag, 2018)
In this study, effect of rotational speed on the characteristic microstructure and mechanic properties of the AISI 1030/AISI 420 stainless steel couple welded by friction welding method was experimentally investigated. The ...
Synthesis and structural characterization of Fe based Ti+Ni3Al+Al2O3 reinforcement composite produced by mechanical alloying
(Consejo Superior Investigaciones Cientificas-Csic, 2020)
The Fe-based Ti+Ni3Al+Al2O3 powder mixture is mechanically alloyed in a Spex ball mill. Composites with Fe-based Ti+Ni3Al+Al2O3 addition were produced at 1000 degrees C sintering temperature for 1 h sintering time. The ...
Effect of carbides on the wear resistance of white cast iron alloyed with 12.7 wt.-% Cr and nickel
(Carl Hanser Verlag, 2020)
White cast iron with about 12.7 wt.-% chromium was alloyed with Ni, W and Mo for heat treatment applications. Heat treatments were performed at a range of 850-1050 degrees C for 1 h in order to distribute M7C3 carbides ...
