Testing of Already Existing and Developing New Compaction Equations during C...IJMER
Powder Metallurgy (P/M) processing of materials to produce conventional P/M parts
involve the compaction of the pre-determined mass of individual elemental, mixed elemental metal
powders or alloy powders and or composite powders into green compacts and sintering them under
reducing atmosphere and or under other protective coatings, thus, after sintering producing
products after mild machining operations. Therefore, compaction represents one of the most
important stages in the production of engineering components using the P/M route. However, the
physical properties such as density and the stress distribution in the green compacts are determined
not only by the properties of the constituents of the powder or the powder blend, but, also by the
pressing modes and schedules. Thus, the present investigation pertains to generate experimental
data on the compaction behaviour of Fe-1.05% graphitesystems with two different iron particle size
ranges and two different powder masses in order to highlight the various aspects of compaction and
also testing out the already existing compaction equations and search for the new ones. Powder
blends of two different iron powder particle size ranges, namely, -106+53µm and -150+106µm
respectively were blended with the required amount of graphite powder of 3 – 5 µm sizes for a
period of 32 hours. Compaction studies have been carried out for two different amounts of both
powder blends. The two amounts taken were 65g and 85g respectively. However, the main attempt
was made to record the load and the corresponding heights and the top punch displacements for
every two tons (0.02MN) of load which was applied in the steps of 0.02MN. Various equations for
compaction were attempted empirically and the already existing ones were also tested. Critical
analysis of the experimental data and the calculated parameters have resulted into several
compaction equations which were arrived at empirically. The regression coefficient ‘R2
’ in each
case where compactions equations were empirically obtained was in very much close proximity to
unity. However, it has been also confirmed that the data of the present investigation were well
taken up by the earlier compactions equations, thus, validating them comprehensively.
Crack Detection of Ferromagnetic Materials through Non Destructive Testing Me...IJMER
The real components have so many defects in the material, which acts as a crack. In fact,
manufacturing of a component is not ideal. In manufacturing several kinds of defects are generated
like voids and inclusions. Thus, it must be check all the critical components through non-destructive
techniques (NDT) to detect the potential dangerous cracks. In Certain crucial components such as
Airplanes, Space Vehicles, Nuclear Plants, Heavy Machinery, Dams, Concrete etc., online monitoring
of defects is necessary. Concrete is different from other construction materials. Concrete can be made
from combination of different materials. Its final properties depend on its treatment at construction
site. To achieve this, sophisticated technologies are used. Ferromagnetic Composite Iron (FCI) is
used in power generating devices and DC brushless Motors. Laminations can be substituted by
Ferromagnetic Composite Iron (FCI) materials which offer a great manufacturing advantage. Non
Destructive testing (NDT) is a major part of quality control. In Non-Destructive testing (NDT)
different materials are tested for surface, volumetric and internal defects present in it. Non
Destructive testing (NDT) is also an assurance that the proposed product is good and reliable. To
apply these techniques, a certain level of skills is very necessary so that maximum amount of
information is fetched related to the proposed product during testing. This paper deals with the Non
Destructive Testing Methodology Used for crack detection in ferromagnetic materials.

Analysis of MOS Capacitor Loaded Annular Ring MICROSTRIP AntennaIJMER
In this paper a new technique is proposed for achieving increased frequency agility by loading
the patch antenna with a MOS capacitor. Theoretical investigations have been carried out for the MOS
capacitor loaded Annular Ring microstrip antenna, for oxide thicknesses from 100 A to 500 A, to predict
the achievable range of operational bandwidth. In spite of numerous advantages, the simple patch antenna
has a low operational bandwidth, which limits its applicability. Hence this technique of MOS capacitor
loaded Annular Ring microstrip patch antenna is to improve the operating frequency range.
The quality of the machined piece and tool life are greatly influenced by determination of
maximum temperature of the cutting tool. Numerous researchers have approached to solve this problem
with experimental, analytical and numerical analysis. There is hardly a consensus on the basics principles
of the thermal problem in metal cutting, even though considerable research effort has been made on it. It is
exceedingly difficult to predict in a precise manner the performance of tool for the machining process. This
paper reviews work on the requirements for optimization of Tool wear so that its life could easily be
predicted.
An Inclusive Analysis on Various Image Enhancement TechniquesIJMER
Digital Image enhancement is the process of adjusting digital images so that the results are
more suitable for display or further image analysis. It provides a multitude of choices for improving the
visual quality of images or to provide a “better transform representation for future automated image
processing. The enhancement technique differs from one field to another field. The existing techniques
of image enhancement can be classified into two categories: Spatial Domain and Frequency domain
enhancement. Many images like satellite images, medical images, aerial images and even real life
photographs suffer from poor contrast and noise. It improves the quality (clarity) of images for human
viewing by eradicating blurs, noise, increasing contrast, and revealing image details.
Potential Use of LPG in A Medium Capacity Stationary HCCI EngineIJMER
Internal combustion engines are extensively used in every field of life in today’s world.
Diesel engines being more efficient are preferred in the industrial and transportation sector in
comparison to spark ignition engines for their higher efficiency, versatility and ruggedness. The major
emissions of diesel engines are oxides of nitrogen (NOx), particulate matter (PM), carbon dioxide
(CO2), carbon monoxide (CO). Among these emissions, oxides of nitrogen (NOx) and the particulate
matter are the reasons of serious concern. For reduction of oxides of nitrogen (NOx) and particulate
matter simultaneously, the use of Homogeneous Charge Compression Ignition (HCCI) have provided a
sustainable solution in the present scenario.
This paper presents the findings of an experimental investigation into the operation of a
compression ignition (CI) engine in homogeneous charge compression ignition (HCCI) mode using LPG
as the main fuel and diesel as pilot injection. Factors that were investigated include engine performance
and emission characteristics and based on the results, LPG was found to be a possible fuel for operation
of a CI engine in HCCI mode.
A methodology using a small pilot quantity of diesel fuel injected during the compression stroke
to improve the power density and operation control is carried out for an HCCI engine based on a
stationary, constant RPM, water cooled diesel engine. The objective of this study is to investigate the
performance and emission characteristics of HCCI engine fuelled with LPG and help understand the
viability of LPG as an alternative fuel in diesel engines for use in the automotive industry.
