Metallic data function

For more reasonable use metallic data, produce its result adequately, those who be necessary to hold all sorts of metal data to be made 0, the function that component part should have below normal operation circumstance (handle a function) the function that reachs its to should be had in the data in cold hot-working process (craft function) .
The carry of the data includes physical function with the function (if specific gravity, melting point, conductivity, thermal conductivity, heat is expansile, magnetic,wait) , chemical function (durable caustic, fight oxidisability) , mechanical function also calls mechanical function.
The craft function of the data shows the data is used to the ability of method of cold, hot-working.
(one) , mechanical function
Mechanical function is the character that outside showing metallic data is in, strength effect plays an expression to come out.
1, intensity: The data is outer force (load) below the effect, revolt is out of shape and the ability of craze. Data unit area suffers load to weigh stress.
2, yielding dot (б S) : Weigh yielding intensity, show the data is in the process that pull pull out, data place suffers stress to arrive at some when critical value, load is added no longer be out of shape be added continuously however or fit 0.2%L. Stress is worth when, the unit uses Newton / millimeter 2 (N/mm2) make clear.
3, tensile strength (б B) also call intensity limit to show the data accepts value of the greatest stress before be pulled. The unit uses Newton / millimeter 2 (N/mm2) make clear.
4, outspread rate (δ ) : The data is after drawing craze, always stretchy the per cent with length of initiative gauge length.
5, section shortens rate (Ψ ) the data is after drawing craze, section is the largest reduce area and former section to accumulate per cent.
6, hardness: Show the data revolts other better thing pressure its outside talent, commonly used hardness determines by its dimensions hardness of dispersed family name (HBS, HBW) with Rockwell hardness (HKA, HKB, HRC)
7, pound tenacity (Ak) : The data defends the ability that pounds load, the unit is joule / centimeter 2 (J/cm2) .
(2) , craft function
Show the data accepts those functions of the ability of all sorts of treatment, processing.
8, cast a function: Pointing to metal or alloy is appropriate function of cast a few craft, principal include shed ability of mould of function, circumfuse; Shorten the ability that the bulk when gender, cast condenses shortens; Slant analyse points to chemical composition not all quality.
9, solder function: Show metallic data solders with pressurization through heat or heating method, two or solder of data of two above metal is received together, interface place can satisfy the character that uses an intent.
10, the top enrages paragraph of function: Point to metallic data can bear issue upset and not the function of break with.
11, cold curved function: Show metallic data can be accepted below normal temperature labyrinthian and not break with function. Labyrinthian degree uses labyrinthian viewpoint α normally (quoin) or D of curved heart diameter makes clear to the ratio of data ply A, a heals big or D/a heals small, criterion the cold curved sex of the data has healed.
12, punch function: Metallic data accepts punch to be out of shape machine and not the ability of break with. Undertake in normal temperature punch calls cold punch. Check method to undertake probation with cupping experiment.
13, cast a function: Metallic data can accept plasticity to be out of shape in v treatment and not the ability of break with.
(3) , chemical function
Point to a metal data and all round the function that medium sweeps chemistry of fit of the revolt when touching or electrochemistry echo.
14, corrosion resistance: Show metallic data defends the ability that all sorts of medium corrode.
15, fight oxidisability: Show metallic data is below high temperature, defend ability of fit oxidation skin.
