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 to temper steel? ?
Heat treating easy, HA! It is the most critical part of bladesmithing. Done wrong and all those hours of work go up in smoke (or a snap of the steel). You'll need a bucket of oil, preferably one that is deep enough to go in point first. If not you'll have to go in edge first, not recommended on a double edged blade, ok for single edge. You'll need to build a charcoal fire long enough for the blade. You will need to blow air under the fire to get it hot enough, the challenge is getting the heat even. You get the fire going and established, put the blade in turning it back and forth (if you keep turning it in the same direction when it heats up you could work a twist in it). When it starts turning red pull it out and touch it with a magnet, if the magnet sticks put it back. Keep heating and repeating until the magnet no longer sticks. Heat a little more, then quench rapidly point first. Don't let the blade lean to one side as warpage will occur. When it cools enough to touch, check with a file. If the doesn't file cut then you've properly hardened the steel and it's ready for temper. Now comes the really hard part. Grind the scale off carefully,preferably with a side grinder with a flap wheel. I've had hard wheel break freshly hardened blades. After cleaning you'll need to put it in an oven (preferred) or use a torch and carefully heat the blade. Watch the temper colors (oven temp 500-550F) or with the torch as the steel turns colors blue to purple for a double edged weapon. Any warpage that occurs needs to be worked out at temping temp.
Q:Can carbon steel be solution annealed?
No. Carbon steel has two different crystal structures, FCC and BCC , depending on the temperature. when you heat steel up and then quench it, it locks the crystal structure into the BCC form. this makes it hard. whereas precipitation hardened austentic stainlesses remain BCC regardless of the temp, so the hardness change is not a function of thermally induced strain. you can anneal carbon steel but the thermal profile is closer to the precipitation profile of PH stainlesses than it is to the Solution annealing profile.
Q:is alloy steel is same with stainless steel?
*Alloy steel is not same as stainless steel. An alloy steel is not the perfect spring steel. Since you are doing the project, please understand the carbon steel,alloy steel and super alloys. Alloy steel is steel alloyed with a variety of elements in amounts of between 1 and 50% by weight to improve its mechanical properties. Alloy steels are broken down into two groups: low alloy steels and high alloy steels. Stainless steel is a type of high alloy steel. *As far as spring material is concern , spring steel or music wire is best suited. Spring steel is a low alloy, medium carbon steel or high carbon steel with a very high yield strength. This allows objects made of spring steel to return to their original shape despite significant bending or twisting. Silicon is the key component to most spring steel alloys. An example of a spring steel used for cars would be AISI 9255 (DIN and UNI: 55Si7, AFNOR 55S7), containing 1.50%-1.80% silicon, 0.70%-1.00% manganese and 0.52%-0.60% carbon. Most spring steels (as used in cars) are hardened and tempered to about 45 Rockwell C. Since sufficient links were given earlier but I like you to go through spring steel as it is your subject matter. I have done the project on The design of a helical compression spring selected material was ASTM A228 (0.80–0.95% carbon).
Q:A steel rod AISI 1040....?

Q:How does water cooling affect the hardness of steel?
When steel is slowly cooled, lots of carbon diffusion takes place because it is not very soluble in steel at room temperature. The carbon is in solution at high temperatures, and is rejected out of the lattice as it cools. And when this happens, the microstructure will consist of ferrite and pearlite, and the lattice structure will be base centered cubic (bcc). If it is cooled fast enough, then the carbon gets trapped in the interstitial sites of the lattice and distorts it to a body centered tetragonal (same as bcc, but elongated in one direction) This elongation strains the lattice and makes it harder. Also, when cooled fast enough the atoms do not have time to diffuse like they normally would and they shear into place. This forms the hard phase of martensite that is desired of heat treated steel. But then it must be tempered back some because it is too brittle.
Q:Methoding - Steel Castings?
It is very difficult to define Methoding of Steel castings by one sentence. Actually it encompasses the total casting process. Normally it would mean a) Pattern design i.e. what type of pattern it would be- wooden, metallic, split or full, loose or fitted on a match plate or any other, how will be the parting line. b) Design of the gating system. c) Design of risering i.e. numbers, size and location of risers. d) Design of molding process i.e. sand system to be used, mold box size. But to do justice to the above mentioned activities, you need to consider other parameters of the casting process such as chemical composition, solidification characteristics, pouring temperature, pouring time, knock out time etc. As I said Methoding of Steel castings means designing of the total casting process from inception to final product.
Q:How difficult is it to harden steel?
Some steel won't 'harden' very much to begin with. Mild steel found commonly around the shop/farm/house has few alloys other than carbon, and may not get the desired hardness no matter what you do. A quick test to see what type you have (mild steel vs. alloy) is to touch it to a grinding wheel.
Q:Is sterling silver safer than surgical steel?

Q:is tool steel reliable steel in construction of a sword?
Yes, its good for machining, but it needs to be hardened once machined. Steel in itself is very weak, but when tempered it can become 10x stronger. Once shaped, heat the sword with a torch until it starts to change color, then dip it into a vat of oil, not water, and the rapid cooling when reform the atoms of the steel.
