目前对材料性能及其组合提出了更高的要求，例如具有良好冷成形性的高强度钢。随着强度的增加，材料的可成形性通常会降低，但对于某些类型的钢，例如TRIP钢，可以获得强度和延展性的优异组合。然而，这些材料不仅用作片材，而且用于其他应用也是令人感兴趣的。薄壁半成品代表了进一步将TRIP钢扩展到体积成形领域的最佳方式。这一趋势假设将找到合适的技术条件，并优化所选生产程序的工艺。在热模拟试验机上进行了增量变形TMT工艺的模型优化试验。通过光学显微镜和电子显微镜对模型处理获得的显微结构进行了分析。
Higher demands are currently being made on material properties and their combinations, for example, high strength steel with good cold formability. With increasing strength, material formability generally worsens, but with some kinds of steels, for example, with TRIP steel, it is possible to obtain an excellent combination of strength and ductility. However, these materials are interesting not only for use as sheets but also for other applications. Semi-products with thin walls represent the best way of further extending TRIP steels into the bulk forming area. This trend supposes that suitable technological conditions will be found and the process for a chosen production procedure will be optimized. The model optimization of the process for TMT with incremental deformations was experimentally carried out on a thermomechanical simulating machine. Microstructures obtained by the model treatment were analyzed by means of optical and electron microscopy.
