Metallurgy
Metallurgy is the study of metals and compounds. It includes the technology and advancement of refinement and casting techniques.
215 Questions
Metallurgy is broadly divided into following branches :
1. Mechanical Metallurgy
2. Physical Metallurgy
3. Extractive Metallurgy
These are the basic divisions and these branches are further divided into various sub categories.
Why hardness value is very important in the metallurgy study?
The hardness value is important because during metallurgy, people can make accurate deductions as to the kind of work the metals can be used for. Hard metals can be used to make knives and propeller rotors.
What does a rolling offset look like?
rolling offsets are used in the piping and sheet metal (duct work) trades, a rolling offset changes the elevation and locaton of the piping or duct usually by using two fittings to offset around obstacles. rolling offsets are used mostly when you are limited to the size of the fittings in order to change your elevation and location rolling offsets are used in the piping and sheet metal (duct work) trades, a rolling offset changes the elevation and locaton of the piping or duct usually by using two fittings to offset around obstacles. rolling offsets are used mostly when you are limited to the size of the fittings in order to change your elevation and location
What are the advantages of powder metallurgy?
Much faster production while holding closer sizes. better quality too.
Why is there is a jump from metallurgy diploma to BCA and then to MCA?
The BCA is most likely a bachelors degree. The MCA is a masters.
What is the impurity difference between pig iron and cast iron?
http://encarta.msn.com/encyclopedia_761559225/iron_and_steel_manufacture.html Provides the answer. basic summary: 1. Pig Iron and Sponge Iron are the result of different production processes 2. Which results in different purities. Pig Iron has a lower purity than Sponge Iron.
The abbreviation
Fe stands for Ferrous material ie iron from which the reinforcement steel bars are manufactured.
The reinforcement steel bars used in RCC (Reinforced Cement Concrete) are designated as Fe415 or Fe500 depending on their Yield Strength. (The numbers 415 and 500 tell about this Yield Strength in N/mm2 the bars are designed and manufactured to have.)
As per IS : 1786 Yield Stress (also known as 0.2%proof stress) of Fe 500 is 500 N/mm2.
So, Fe500 steel means the reinforcement steel rods (or bars) that can safely withstand an Yield Stress of 500 N/mm2.
What is the sharpest material?
diamond is the hardest material and if it is sharpened , then it is the sharpest material
What is the chemical chemical composition of HYSD bars?
For example the steel Fe 500 1586 contain 0,3 % carbon, 0,05 % sulfur, 0,05 % phosphorus.
How much kg of steel need for 10sqft?
None, since there can be no direct conversion.
A square foot is a measure of area in 2-dimensional space while a kilogram is a measure of mass. The two measure different characteristics and, according to the most basic principles of dimensional analysis, any attempt at comparisons or conversions between the two are fundamentally flawed.
What are the metals called which occur in the rocks in the form of?
The metal in rocks is metal ore. Copper ore, iron ore, and so on. In general, once the ore has been quarried or mined, the ore is crushed and smelted (heated to a high temperature) allowing the now molten metal to be retrieved. The waste rock is dumped. Further processing is needed to obtain a finished metal in as pure a state as possible.
What is the difference between hot and cold working?
The names say it all...
Cold working is done cold, i.e. part at room temperature. It essentially pushed into something to deform it. This yields the part, technically increasing its yield for further use, but it will decrease the stress required to go from its new yield to its max tensile. Be advised, for very thick parts, like bars above 2", only the outer portions will cold work, the core will keep the same properties as un-worked metal.
Hot working heats the part up above its recrystallization temperature so along with deformation, the part recrystallizes, thereby not cold working it. Hot working does not give a yield strength increase like cold working does.
What's the best way to invest in gold?
As with any investment, the most important thing you can do is to research the market and understand the pros and cons of investing. A great place to start would be a website such as investopedia.com, which compares investment strategies and can help you make the right decisions.
Metals and alloys have been used extensively in personal appliances and industrial instruments due to their excellent mechanical property, as well as electrical and thermal conductivity. Among different types of biomaterials, a favorable combination of high strength and resistance to fracture that metals provide warrants their reliable long-term implant performance in major load-bearing situations. The processing and composition of metals and alloys determine their microstructure and that in turn determine properties. For example, carbon steel which is also known as mild steel is useful for making
What are the disadvantages of powder metallurgy?
1. The production of powder for metallurgy is very high.
2. The products of metallurgy can have limited shapes and features.
3. This technique causes potential workforce health problems from atmospheric contamination of the workplace.
4. The tooling and equipments require for powder metallurgy are very expensive, therefore becomes main issue with low production volume.
5. It's difficult to produce large and complex shaped parts with powder metallurgy.
6. The parts produce by powder metallurgy have low ductility and strength.
7. Finally divided powder like aluminium, magnesium, titanium and zirconium are fire hazard and explosive in nature.
8. This technique is not useful for low melting powder such as zinc, cadmium and tin as they show thermal difficulties during sintering operations.

To create an alloy with 40% copper, you would need to mix equal parts of the 20% alloy with the 70% alloy. This means you need to mix 50 ounces of the 20% alloy with 50 ounces of the 70% alloy to achieve the desired 40% copper content in the final alloy.
No, lead is not a suitable material for making wire. Lead is a soft and heavy metal that does not have the necessary properties to be drawn into thin, flexible wire like other metals such as copper or aluminum.
