Calculates the Vickers pyramidal diamond hardness of martensite, bainite or ferrite/pearlite mixtures.
Language: | FORTRAN |
Product form: | Source code |
PROGRAM MAP_STEEL_HARDP
DOUBLE PRECISION C, SI, MN, NI, MO, CR, V, COOL, HV
INTEGER J
MAP_STEEL_HARDP calculates the Vickers pyramidal diamond hardness for martensite, bainite or ferrite/pearlite, as a function of the cooling rate and the concentrations of carbon, silicon, manganese, nickel, molybdenum, chromium and vanadium.
In the case of martensite, the effect of molybdenum is assumed to be the same as chromium.
Parameter | Type | Description |
---|---|---|
C | real | C is the carbon concentration (in weight percent). |
SI | real | SI is the silicon concentration (in weight percent). |
MN | real | MN is the manganese concentration (in weight percent). |
NI | real | NI is the nickel concentration (in weight percent). |
MO | real | MO is the molybdenum concentration (in weight percent). |
CR | real | CR is the chromium concentration (in weight percent). |
V | real | V is the vanadium concentration (in weight percent). |
COOL | integer | J takes the value 1, 2 or 3 according to:
|
Parameter | Type | Description |
---|---|---|
HV | real | HV is the Vickers hardness. |
Warnings are given if the sum MN + NI + CR + MO > 5, or if COOL is outside the range [0,900] kelvin per second.
The range of applicability of the program is defined by the requirement that MN + NI + CR + MO <= 5, and the cooling rate be within the bounds [0,900] kelvin per second.
