Q:Heat treatment of mild steel? Process description macro-micro
Alright, usually whu heat you heat treat mild steel, this is because you would like it stronger than you got it. To do this you must alter the grain structure of the part or in other words, the CRYSTALLITES. Ultimately you'll end up altering the nature of the grains structure changing the tensile strength it can handle, yield strength, and even change the elongation percentage that it can tolerate under load. Heat treatment controls the rate of diffusion, and the rate of cooling within the microstructure to create these elements. Usually what they use to do this is add an element to it to make it stronger such as carbon to increase its rockwell hardness, which by the way the lower you go the harder the part can become. Heat treatment can be used in more ways than this. It can also be used to weaken the parts grain structure. This will lower the parts mechanical properties making it softer and more ductile or easier to manipulate if you have to bend it into a particular shape. Typically if you allow the part to cool after heat treatment it does go through annealing. The part will be heat treated into different stages. The first being the austenitic crystal phase which depending on how hard and strong you want it, will be at its peak. When it is cooled, it will go through a will transform to martensite which is a hard yet brittle crystalline structure. Martenised part will usually be tempered to a certain degree to improve the mechanical properties to what is needed. There is more to this and you can use the link below to read more about it.
Q:How did the planes break the steel?
1 nothing is unbreakable! 2 it is a question of velocity not that the plane was going very fast but! the difference between an explosion and a detonation is if the flame front is faster or slower than 1000 meter per second If you burn Hydrogen it burns fast, more than 1000 meter per second at that speed a plastic pen like those you use every day will puncture through a steel 2X4 used in modern building walls it is not thick steel but it is still steel! and the plastic piece is hardly deformed Those talking about aviation fuel... this is long, very long after the fact Guru
Q:Warhammer 40k:Steel Legion...Buying Minatures?
here are a couple of things about the steel legion. you should have a lot of mechanized units, have chimaras for rvery squad if posible, artillery fire helps a hell of a lot. also sentinals and leman russes and hell hounds also help. if in apocolypse, use banblades and titans. storm trooper squads should be your base squadrons. put them in chimeras and get near the action, drop 'em off and rapid fire like CRAZY!!! the steel legion loves heavy weapons so remember to get some heavy weapons platforms. there favourite weapons are grenade and missle launchers. there is also an officer you can buy with a power sword with the steel legion look. steel legion are big xeno hunters. because commisar is a ork killer you should be allowed to field him. ratling/ sniper squads also help and if you can get a vindicare assassin that is very useful.
Q:Steel shot?
In my experience with steel shot, I found that the higher quality stuff usually just patterns more consistently. Although I prefer Federal, any of the other major manufactuers are also great.
Q:How does water cooling affect the hardness of steel?
Quenching results in smaller grains than air cooled. This means more boundaries, which means harder steel.
Q:where did WTC steel go?
Some of the steel was recycled for sale to other countries where they aren't so picky about reusing building materials. NIST had 200 pieces of the steel for their investigation, which they returned last year. This was covered in the press. The rest of the steel was held at JFK international airport's Hangar 17. Much of it will be placed/has been placed in the new museum beneath the Memorial at the WTC site. Thousands of pieces are being given out for 9/11 memorials all over the world. Just about every day you read in the newspaper about another piece going here or there to this city or that city. Yes, a lot of the steel was tested for a number of chemical compounds. It had to be for safety reasons before storing it and giving it out. Depending upon what countries the recycled beams were sent to and their rules, it was sometimes tested at the ports of entry over there, as well.
Q:What is harder Gold or steel?
steel. it's used to support skyscrapers lol. gold can be molded easily into jewelry. although both gold and steel are both malleable, steel is harder to shape.
Q:Whats better, 1045, or 440 stainless steel?
1045 stainless is better
Q:steel plow?
If you're willing to substitute the word iron for steel (steel came a good bit later in history), the Girard plow from the 1300's in Belgium would be the first example known. It's named after the guy who invented it (Girard). How did it work? Like any other plow! You drag it along and it makes a trench of sorts in the ground! It was used for agricultural purposes. As for how it was produced, you need to look up the history of the Iron Age to understand how they started to use iron back in about 1200BC to make tools.
