Material science and engineering questions and answers pdf

Carbide is a chemical compound in which carbon is combined with a metallic or semi-metallic element. Materials can be broadly classified into metallic, polymeric, ceramic, and composite. The microstructure of the material is influenced by its physical properties which in turn govern the application of these materials in industrial practice.

Steel is made of iron, carbon, and some other alloy, and non-alloyed. Different alloy elements have different effects on steel Mechanical and Physical properties. C Carbon is the most important constituent of steel. It can raise hardness, tensile strength, and resistance to wear and abrasion but can reduce the ductility, toughness, and machinability of steel.

Si Silicon is a deoxidizer and detoxifier. It increases ductility, tensile and yield strength, hardness, enforceability, and magnetic permeability. Mn Manganese is a detoxifier and can react with sulfur to improve enforceability. It increases tensile strength, hardness, hardenability, resistance to wear, and the rate of carbon-penetration in carburizing but decreases the tendency toward scaling and distortion.

S Sulfur improves machinability in free-cutting steels, but without sufficient manganese, it produces brittleness at red heat. It decreases weldability, impacts toughness, and ductility. Cr Chromium is very important in steel. Co Cobalt increases strength and hardness and permits higher quenching temperatures and increases the red hardness of high-speed steel.

CB Columbium used as stabilizing elements in stainless steel. Thus, localized precipitation of carbides at grain boundaries is prevented. Cu Copper negatively affects forge welding but does not seriously affect arc or oxyacetylene welding.

Nickel Ni increases strength and hardness without sacrificing ductility, toughness, resistance to corrosion, and scaling at elevated temperatures when introduced in suitable quantities in high-chromium stainless steels. Ta Tantalum used as stabilizing elements in stainless steel. Ti Titanium used as stabilizing elements in stainless steel. Corrosion of the sea water and steam boiler may occur in three ways, by oxidation, by electrolytic dissolution, and by acid attack.

Metastable structures are no novelty in metallurgy. The traditional practice of metallurgy has centered on the formation, characterization, and understanding.

This upsurge reflects developments in the techniques of melt quenching, condensation, and irradiation of materials, as well as in the kinetic understanding of structural evolution.

Annealing is a heat treatment that alters the physical and sometimes chemical properties of a material to increase its ductility and reduce its hardness for making it more workable In metallurgy and materials science. It involves heating a material that increases its recrystallization temperature, maintaining a suitable temperature for an appropriate amount of time.

There is no fixed formula to calculate the firing order of an engine because it has no fixed firing order. Even for engines with the same cylinder count. For instance, the 4 cylinders Yamaha R1 has had a wave-like firing order, since or so cutting down on vibrations but making it sound like a parallel twin.

If you want to know about the firing order, look into maintenance manuals or try sending an email to the manufacturer and ask him nicely. Ceramics are an inorganic non-metallic solid made up of either metal or non-metal compounds that have been shaped and then hardened by heating to high temperatures known as a kiln.

Ceramics are generally made by taking mixtures of clay, earthen elements, powders, water that makes them hard, corrosion-resistant, and brittle as the desired shape. Ceramics are covered by decorative, waterproof, paint-like substances known as glazes. Allotropy is defined as the existence of a chemical element in more than one crystalline form, which is different in the arrangement of atoms and the occurrence of molecules in crystalline solids that contain different numbers of atoms.

Annealing is a heat treatment that alters the microstructure of a material causing changes in properties such as strength, hardness, and ductility whereas Quenching is the cooling process of the material from the higher room temperature generally, faster cooling like dipping in water, brine solution, oil, etc.

Vacuum Induction Melting is a Process that involves the melting of metal under vacuum conditions. Powder metallurgy is a metal-forming process. It is performed by heating compacted metal powders to just below their melting points.

The most useful and important liquid for dissolving gold is aqua regia, royal water , composed of two parts of hydrochloric muriatic acid, and one part of nitric aquafortis. The main purpose of the SPCC rule is to help facilities prevent a discharge of oil into navigable waters or adjoining shorelines. Thank you. TTT stands for time-temperature transformation which is basically a time-temperature transformation curve. CCT curves are useful to obtain different metastable products by controlling the rate of cooling.

In the CCT, the temperature is changing continuously, we get phase transformation at continuous cooling. Electrical Engineering Interview Questions. Software Engineering Interview Questions.

Do you have exposure in understanding physical and chemical behaviour of metals and alloys? Metallurgy is a domain of material science and engineering that studies the physical and chemical behaviour of metallic elements their inter metallic compounds and their mixtures which are called alloys. Metallurgists develop and manufacture metal items and structures that tiny precision made components to huge engineering parts. Metallurgists usually specialises in a specific area such as process, chemical or structural metallurgy. So, engineering graduates with metallurgy as a branch can try out their luck as metallurgist, metallurgical engineer, quality engineer, mineral processing engineer, refining and midstream engineer, product development engineer etc by looking at the below listed metallurgy job interview questions and answers and choose your rewarding career. This transformation happens during tempering heat treatment of quenched steels, or during slow cooling in that temperature range. It is fine dispersed carbide in a ferrite needlelike matrix.

What is Iron Ferrite, what is it used for, and where is it found? Well, a few definitions match your question. First, "ferrite" is the name metallurgists give to the body-centered-cubic phase of iron and its alloys. The 'body-centered-cubic' phrase refers to the way the atoms are arranged in the lattice, to distinguish it from "austenite" which is the face-centered-cubic arrangement. Generally, ferrite is a pretty pure iron- the core iron used in electrical transformers, for example, is ferritic-but there are also some stainless steels that are ferritic.
