The plastic deformation included in the technological processes of sheet metal forming allows the production of different components with different geometries. Therefore, the formability of metallic materials is an essential feature in stamping processes. One of the inevitable scattering sources when considering these processes is the variability of material properties, which can change from coil to coil, from batch to batch and from supplier to supplier. This constitutes a significant obstacle in improving the quality of any manufacturing process. The current study investigates the formability and the mechanical characterization of a defined advanced high strength steel grade, considering different suppliers, coils, and batches in order to evaluate its influence on the results of the sheet metal forming process. A microstructure analysis is also considered to understand the impact of micro-scale variables (e.g. grain size) in macro-scale behavior. Additionally, numerical simulations were taken into consideration to evaluate the influence of mechanical characterization in the results.

钣金成形技术过程中包括的塑性变形允许生产具有不同几何形状的不同组件。因此，金属材料的可成型性是冲压过程中的基本特征。考虑这些过程时，不可避免的散射源之一是材料特性的可变性，该特性会随卷材，卷材，批次与批次以及供应商之间的变化而变化。这对提高任何制造过程的质量构成了重大障碍。当前的研究调查了定义的高级高强度钢牌号的可成形性和机械性能，并考虑了不同的供应商，卷材和批次，以评估其对钣金成形工艺结果的影响。还考虑进行微观结构分析以了解微观变量（例如晶粒尺寸）对宏观行为的影响。此外，还考虑了数值模拟，以评估结果中机械特性的影响。
