------------------------------------------------- Alloy Steel is a metal alloy whose major component is iron‚ with carbon content between 0.02% and 2.14% by mass. An alloy is a metallic solid solution composed of two or more elements. Complete solid solution alloys give single solid phase microstructure‚ while partial solutions give two or more phases that may or may not be homogeneous in distribution‚ depending on thermal (heat treatment) history. Alloys usually have different properties from those

Ms Sanghamitra‚ R&D Refractory Department from TATA STEEL‚ Jamshedpur‚ gave a talk on “STEEL MAKING REFRACTORY”‚ on 12th September 2012 at 11:00 AM at Ceramic Engineering department. Process chart of TSL‚ INDIA was first addressed. So‚ it all starts with iron ores and fluxes (limestone) to be mixed and then pelletized in a sinter plant. At the same time‚ raw coal is processed to form coke in a coke plant and then sintered pellets along with coke are fed to a blast furnace. Hot metal is obtained

The book “Purity of Heart” is a composition of letters written by the founder William Booth. Originally‚ these letter were shared in weekly Salvation Army gatherings to help Salvationists continue in Holiness‚ then later they were put in book form. Holiness is viewed as synonymous to a “pure heart; this is define in chapter eight‚ by William booth. The book is divided in ten chapters that are interrelated and build upon each other. It begins by defining purity of the heart in general terms. Next

solution. The sample consists of eleven stainless steel wires and eleven Nitinol wires after being in clinical use from one to eight months. The used wires‚ unused portion of Nitinol and stainless steel wires and Nitinol wires which had been subjected to anodic dissolution for two minutes were mounted for SEM observations. The results of the study demonstrated that unused nitinol wire showed large variations in surface texture when compared to stainless steel wire. SEM studies showed no discernible difference

EXPERIMENT #1: THE PURITY AND PURIFICATION OF SOLIDS MELTING POINTS ABSTRACT Melting points of different mixtures of naphthalene and biphenyl were examined in this lab. Samples of these various mixtures were collected and tested by different individuals in the lab in order to find the eutectic point of biphenyl. Unknown substances were then tested using the mixture melting point method in order to determine their identities. INTRODUCTION The melting point of a solid is the temperature

The Purity and Purification of Solids Melting Points CH-337 Abstract: The purpose of this experiment was to find the eutectic point for the mixture of naphthalene and biphenyl. This was done by measuring the melting point of both pure substances and five mixtures of different ratios. The purpose of the second section was to identify an unknown sample by measuring its melting point and mixing it with two known substances and comparing them. The results suggest that the eutectic point is closest

The Fight for Food Purity Economic Botany September 29‚ 2013 Michael Pollan’s film‚ The Botany of Desire‚ opened my eyes to the complicated relationship between people and plants. Pollan opened up with the following statement: “Flowers. Trees. Plants. We ’ve always thought that we controlled them. But what if‚ in fact‚ they have been shaping us?” (Pollan‚ PBS) I paused the film and took a few minutes to let this soak in. I was always under the impression that we
