Surface hybrid nanocomposites via friction stir processingmohammed noor
Friction stir Processing (FSP) is a new innovative technology developed based on the principle of Friction Stir Welding (FSW) technique.
In FSP, the ceramic particulates are reinforced into the base metal by adding it into the groove and Friction Stir Processing (FSP) is performed.
In this study, the aluminum alloy 6061 is chosen as the base metal, alumina and graphite Nano powder as reinforcement.
The process parameters such traverse speed of 64 mm/min and the tool rotational speed of 1060 rpm and tilt angle of 2deg were selected, The Friction Powder Processing was carried out on vertical milling machine.
New parameters such as powder type and number of passes were involved and we also study the effect of heat treatment.
The influence of FSP was checked using some tests such as the microstructure analysis that was carried out using optical microscope (OM) and the mechanical characteristics were analyzed using tensile test and hardness test.
The micrograph results revealed that powder particulates were evenly distributed in the stir zone and reduction in grain size also observed; the reason for the grain size reduction was stirring action of the FPP tool’s pin.
The tensile strength results showed a significant improvement in strength by a percent of
50% compared to base metal but when T6 heat treatment is applied, the tensile strength decreased.

EXPERIMENTAL INVESTIGATION AND MATERIAL CHARACTERIZATION OF A356 BASED COMPO...sathish sak
Recently friction stir processing (FSP) has emerged as an effective tool for enhancing sheet metal properties through microstructure modification. Significant grain refinement and homogenization can be achieved in a single FSP pass leading to improved formability, especially at elevated temperatures.
FSP is a solid-state process where the material within the processed zone undergoes intense plastic deformation resulting in dynamically recrystallized grain structure.
Most of the research conducted on FSP focuses on aluminum alloys. Despite the potential weight reduction that can be achieved using Titanium dioxide(B4C) alloys.
In this work, we examine the possibility of using FSP to modify the microstructure and properties of commercial A356-B4C alloy particles. The effect of various process parameters on thermal histories, resulting microstructure and properties to be investigated.
Southern Machinery has proven success in designing,

54. Ø An 80 MT ingot mold for the production of initial ingot for back up rolls and similar products
was casted in melting shop of E.I.CO
Ø The weight of this ingot mold was about 59 MT, length 2900 mm, diameter 1950 mm, with 24
faces. Compared to similar ingot mold in the market it is distinguished with its H/D, Taper,
number of faces and other metallurgical specifications.
Ø TO produce this ingot mold, a new design, casting of cast-iron in EAF, simultaneous casting
of two 50 MT ladles, and in-house machining were employed. 54
55. The largest Slag pot in Iran with 40 MT capacity (3m length, volume of 30m3) for carrying slag
was produced at E.I.CO. Esfarayen Industrial Complex is one of the few plants in the world that
can produce such a ladle.
55
56. Ø For the first time in the Middle East VSD melting was successfully performed at E.I.CO With this method it
is now possible to produce high quality products with excellent mechanical properties.
Ø In this method super heavy slabs with the weights of 50, 80 and 110 MT were put under vacuum for the
subsequent casting process.
Ø The main advantage of this method compared with conventional methods (at atmosphere casting) is to
minimize the absorption of undesired gases in steel. Such a gases would cause problem in further processing
of the steel down the road.
Ø Reducing these unwanted gases is very beneficial in production of shafts for turbines and large shafts for
other sensitive industrial applications.
56
57. For the firs time in the Middle East back-up rolls are produced with forging
method for Mobarakeh Steel Co. in Isfahan, Iran. The weight range is 30-45 MT
57
58. Ø The weight of initial ingot for this piece is 60 MTs (the heaviest ingot being cast in Iran)
Ø The country became self-sufficient for importing heavy forged products up to 45 MT
58
