Abstract :

The case study project is significant since mild steel is used in structure, case hardening, gears, free cutting steels, shafting, forging etc. Mild steel plates were tested for mechanical properties like hardness, tensile strength, yield point etc. Later on the plates were joined by submerged arc welding and the mechanical properties were estimated again. Also weld ability, harden ability, tensile test etc. were conducted for the same result. ....etc

Abstract:
Infrared interruption counter is a reliable circuit that takes over the task of counting number of interruptions very accurately. When somebody enters into the room, then the Counter is Incremented by one. The total number of Persons inside the Room is displayed on the seven segment displays.The microcontroller does the above job it receives the signals from the sensors, and this signals operated under the control of software which is stored in ROM.
All the above systems are controlled by the Microcontroller ....etc

INTRODUCTION

Tribology is defined as science and technology of interacting surfaces in relative motion and of related subjects and practices. However the subject Tribology generally deals with the technology of lubrication, friction control and wear prevention of surfaces having relative motion under load.
The two main constituents of Tribology are friction and wear, which controlled and reduced, automatically increases the service life of machine elements.
In past few years, wood iron and skin have been used as journ ....etc

A microcontroller (or MCU, short for microcontroller unit) is a small computer (SoC) on a single integrated circuit containing a processor core, memory, and programmable input/output peripherals. Program memory in the form of Ferroelectric RAM, NOR flash or OTP ROM is also often included on chip, as well as a typically small amount of RAM. Microcontrollers are designed for embedded applications, in contrast to the microprocessors used in personal computers or other general purpose applications consisting of various discrete chips.

A STUDY ON WEAR AND EROSION PROPERTIES OF RAIL STEEL



Introduction:
Steels represent the most important group of engineering materials as they have the widest diversity of applications of any of the engineering materials. Generally, carbon is the most important element profoundly affecting the mechanical properties of the steels. The term steel is used for many different alloys of iron. These alloys vary both in the way they are made and in the proportions of the materials added ....etc
