Property Optimization Of Ferromagnetic Shape Memory Alloys With Respect To Cost, Ajit Behera
Property Optimization Of Ferromagnetic Shape Memory Alloys With Respect To Cost, Ajit Behera
Ajit Behera
Ferromagnetic shape memory alloys (FSMAs) are the interesting materials exhibiting shape memory effect and magnetism simultaneously. They show magnetic field-induced strains at room temperature greater than any magnetostrictive, piezoelectric or electrostrictive material, and faster frequency response than temperature driven shape memory alloys. Among various FSMA materials, Ni-Mn-X (X =Ga, In, Sn, Sb) have gained considerable interest due to their multifunctional properties such as shape memory effect, magnetocaloric effect, magnetoresistance, etc., associated with first order martensite to austenite structural transition. FSMA spread its application in broad area from aerospace industry to medical application, but not vividly use; because of its high …

Now a day materials have been a key to increase the performance of automotive parts, which point out to develop a new materials having better property. Main objective is to achieve increase in quantity and quality of automotive parts produced and for an optimum performance along their life cycle. Cast iron has remained a competitive material due to its low production cost. In fact, among the cast iron group one of alternative lightweight alloys is compacted graphite iron (CGI). Nowadays it is accepted that, CGI can effectively reduce the total weight of an automobile by virtue of its high strength- …

Cryogenic Technique For Processing Steel Treatment, Ajit Behera
Ajit Behera
Cryogenics or deep freezing have been around for quite some time. There is documented research from as far back as the 1930’s where German companies used it on components of jumbo aircraft engines. Cryogenic processing had its US origins in the 1940s. Cold treatments or sub zero treatments are done to make sure there is no retained austenite during quenching. Cryogenics is a relatively new process and to eliminate retained austenite, the temperature has to be lowered, but one that using correct procedures can bring substantial economic benefits. In cryogenic treatment the material is to be deep freeze temperatures of …

The Natural Composite: Spheroidal Graphite Iron, Ajit Behera
Ajit Behera
The conventional materials are nowadays not sufficient to cater to the variety of uses and exposure to various environments that may take place while they are put into use. Hence this leads to the development of composites, which nearly suffice the above two conditions. Composite material is a material composed of two or more distinct phases (matrix phase and reinforcing phase) and having bulk properties significantly different from those of any of the constituents. In this developing age for iron industry there is large demand for spherodial Graphite iron (S.G. Iron). S.G. Iron also known as a composite in which …

The work presents emission factors of main air pollutants for installations of ArcelorMittal Poland S.A. Unit in Krakow (Poland) in comparison with analogous characteristic emissions for iron and steel industry in West Europe. In the comparison four installations (to coke, sinter, pig iron and steel production) were taken into consideration. The emission rates from ArcelorMittal Poland S.A. Unit in Krakow were estimated on the basis of the emission levels and production data from 2004, when took place the most significant production of liquid steel during last several years. As a result of the analysis, most the emission factors (with the …

The Ag-In-Sn system, as one of potential lead-free solder materials, was studied in this paper. The investigated alloys were chosen from two sections, with molar ratio of In:Sn equal to 1:4; 1:2. DTA, XRD, SEM and microhardness investigations were used in order to determine structural characteristics of chosen Ag-In-Sn ternary alloys.

The article presents a complex analysis of the impact of the technology of continuous casting of steel (CCS) on the rate of the air pollutant emissions from one of the Polish steel and iron plants. The emission sources occurring in the production process have been identified and their rate has been determined. The implementation of CCS has brought about significant changes in the production cycle of the steel plant and it also has caused an increase of the production effectiveness of steel products. The calculated environment effects have shown a considerable emission decrease of all pollutants in the scale of …

The work shows the impact of alkali metals in the sintering process on effectiveness of the electrostatic precipitator and dust emissions into the air. The results of analysis of the content of Na and K in dust discharged from the sinter strand and emitted to the air are presented. It was found that this content is subject to large fluctuations and significantly increases in the dust phase after electrostatic precipitators. Using the balance sheet data, the effect of loads of Na2O and K2O compounds contributed to the sinter mix on emissions of dust. It was also observed high variability of …

The article describes the problem of the presence of sulfur in the blast furnace process and identifies emission sources of sulfur compounds in this process. On the basis of the measurements and calculations, the types and quantities of these compounds emitted to the air were determined. It was found that pig iron smelting in a blast furnace causes emissions of COS, SO2 and H2S. These emissions occur by losses of blast furnace gas (COS and SO2), transport of blast furnace slag inside the furnace hall (SO2) and treatment of the slag by granulation (H2S). However, the most important are only …

The paper presents the results of a comprehensive study of issues related to emissions of fluorine compounds from ferrous metallurgy processes carried out over the last few years. As part of this study raw materials used in these processes were analyzed in terms of fluorine content and its impact on the amount of air emissions of fluorine compounds. Also determined by measuring the concentration levels and emissions of fluorine in the gaseous and solid phase, including water-soluble compounds (considered to be toxic).
