Claim 3:
4. The method according to claim 1, wherein the microstructure mtarget is selected from a group consisting of:
100% of austenite,
from 5 to 95% of martensite, from 4 to 65% of bainite, the balance being ferrite,
from 8 to 30% of residual austenite, from 0.6 to 1.5% of carbon in solid solution, the balance being ferrite, martensite, bainite, pearlite and/or cementite,
from 1% to 30% of ferrite, from 1% to 30% of bainite, from 5 to 25% of austenite, the balance being martensite,
from 5 to 20% of residual austenite, the balance being martensite,
ferrite and residual austenite,
residual austenite and intermetallic phases,
from 80 to 100% of martensite and from 0 to 20% of residual austenite,
100% martensite,
from 5 to 100% of pearlite and from 0 to 95% of ferrite, or
at least 75% of equiaxed ferrite, from 5 to 20% of martensite and bainite in amount less than or equal to 10%.
