The impact of the alloying elements Cr, Mn, N and Cu on industrial processibility and mechanical properties is analyzed, using methods from the project "steel – ab initio". Alongside thermodynamic simulations, experiments will be conducted at the RWTH Aachen University. Those experiments include hot-forming tests, quasistatic and dynamic tensile tests, Nakajima-tests and metallographic analysis. The industry partner Outokumpu Nirosta GmbH analyzes the corrosion resistance of specific alloys and validates the laboratory experiments by employing their pilot continuous casting plant.

采用“钢-从头算”项目的方法，分析了合金元素Cr、Mn、N和Cu对工业可加工性和机械性能的影响。除了热力学模拟，实验将在RWTH亚琛大学进行。这些试验包括热成形试验、准静态和动态拉伸试验、Nakajima试验和金相分析。行业合作伙伴Outokumpu Nirosta GmbH分析了特定合金的耐腐蚀性，并通过使用其试验性连铸设备验证了实验室实验。
