    • Processes for manufacture of metal components with high hardness and plasticity by deforming with high degree of deformation of metals, in particular steels, of which the deformation leads to a hardening by TWIP (Twinning Induced Plasticity) or SIP (Shearband Induced Plasticity) Effect, wherein the metal after the final step of annealing or crystallization annealing is deformed in at least one step into a semi finished product or the finished metal component, wherein the total elongation is in the range of 10 to 70%, as well as semi finished products, in particular continuous sheets, of steel with TWIP (Twinning Induced Plasticity) or SIP (Shearband Induced Plasticity) Effect, wherein the semi finished product exhibits a tensile strength of greater than 800 MPa and an elongation of greater than 35%.
    • 通过使变形导致通过TWIP(结合诱导的可塑性)或SIP(剪切带诱导的可塑性)效应的硬化的金属,特别是钢的高度变形而变形而制造具有高硬度和可塑性的金属部件的方法,其中 在退火或结晶退火的最终步骤之后的金属在至少一个步骤中变形成半成品或成品金属组分,其中总伸长率在10至70%的范围内,以及半成品, 特别是具有TWIP(结合诱导塑性)或SIP(剪切带诱导塑性)效应的钢的连续片材,其中半成品表现出大于800MPa的拉伸强度和大于35%的伸长率。
