Failures of boiler in Thermal Power Plant are the most criticized area now a day. Everyday the country is losing a good amount of power due to shut down of the boilers. This failure has a tremendous effect on the national ...
HSLA steels have acquired a significant position, in the engineering arena as the most important ferrous alloys for design and fabrication of structures.
Application of HSLA steels at present is accepted, for almost all ...
In the present investigation boiler steels SA213-T1 1, SA213-T22 have been taken as candidate materials. Specimens have been subjected to erosion in silica slurry for 4 cycles of 6hr. duration and the erosion rate for two ...
Superalloy development is prompted by the need of high strength at high temperature and requirement, of heat resistant materials in aircraft -engine turbo superchargers, and gas turbine engine. The super alloys in use are ...
The process of electroless deposition is one of the most elegant methods available for the production of coatings. The techniques involves the auto catalytic reduction, at the substrate/solution interface, of cations by ...
To seek out the desired performance, a process is restrained to operate in a predetermined manner i.e. it is controlled. Restraint is usually achieved by controlling a selected physical variable vital to the performance ...
Grain refinement of aluminium and its alloy castings through additions of grain refiners has been a common industrial practice. In this work, a number of routes were explored for the synthesis of Al-Ti-C master alloys. ...
Most of the structural components these days require high strength to weight ratio. This has been made possible by use of high strength steels. But the susceptibility of high strength steels to stress corrosion cracking ...
In the present work effort has been made to study the friction and wear behaviour of TMA treated 2014 Al-alloy. On the basis of observations and analysis of the worn surfaces, the wear debris, friction co-efficient and ...
Welding is widely recognized as an important joining technique in engineering practice and as a consequence, welding is used in many critical applications. These welded structures are subjected to a variety of service ...
Malleable iron is characterized by containing graphite in an aggregated or nodular shapes in the matrix of ferrite. It possesses strength at par with low carbon steels, making it suitable for wide range of applications ...
Powder metallurgy is fast growing field for production of engineering components. Aluminium alloys, owing to their properties, have a strong potential for use as bearings. Their use in antifriction application in combination ...
Stellite coatings on stainless steel have been provided using high velocity oxy-fuel (HVOF) thermal spray process with assistance from Bharat Heavy Electric Limited (BHEL), Haridwar and Central Scientific Organization ...
In iron and steelmaking, as in other industrial activities, increasingly, stringent customer requirements for product quality and regularity lead to tighter control of manufacturing processes. Today Iron and steel makers ...
Fluidity is the capability of a metal or an alloy to All a mould fully without chocking due to premature solidification. When molten metal flows in the mould, it is in contact with the mould wall,. which is lower in ...
The surfaces of polypropylene (PP) have been exposed to DC glow discharge to enhance wettability of the polymers in order to improve their adhesive joint strength with steel. The surface modification of the polymers have ...
Die is the main tool in press forging and drop forging. Die design of forging is done primarily according to rules of thumb and formulae and data from forging
design handbook or designer's experience. This prevailing ...
The present study has been done on high temperature Fe,- based alloy uncoated and coated with stellite. The study has been done in salt mixture containing 40% Na2SO4 and 60% V205 environment and in air. The erosion study ...
The thermal power plant is a plant based on boiler - turbine system and using coal / gas as fuel for the generation of steam. It provides most of the world's supply of electricity. It has been estimated that failures of ...
In the recent years, the metal forming industry has been striving for quality improvement and cost reduction to meet the increasing stringent specification requirements and strong competition in the world market. In the ...
