项目摘要
The Canadian government and automotive industries regularly review the policies, standards and regulations to ensure the safety of both drivers and passengers, as well as to meet the annual greenhouse emission target from the present 704 megatonnes to 517 megatonnes of carbon dioxide equivalent by the year 2030. The proposed metallurgical research program is aimed to reduce the greenhouse emission of Canada by improving the fuel efficiency of automotive vehicles while strengthening the Canadian economy, through the development of a novel, lightweight, clean and economic third generation advanced high-strength steels (AHSS) using unconventional alloying concepts with manganese content of 8-10 wt%. Steel is not an obsolete material. Despite the development of other metallic lightweight materials for automotive parts, significant parts of the body-in-white are still and will always be made of steel in the foreseeable future. This is because of its exceptional combination of economy, strength and durability. In fact, steel industries around the world are aggressively continuing to develop the next generation AHSS. This project will be divided into four major phases. The first phase is dedicated to alloy design, stacking-fault energy (SFE) analysis, thermodynamic assessment, and casting of novel AHSS. These medium-manganese steels will be designed to achieve tensile strengths of more than 1000 MPa with elongations of 30-40%. The second phase involves heat treatment and cooling cycles of these steels to establish the equilibrium phase transitions, cooling curves and phase diagrams. The third phase involves laboratory-scale simulation of thermomechanical processing such as hot rolling and hot forging to assess the formability of these materials. The crashworthiness will be evaluated by performing high-speed deformation experiments. The fourth and final phase covers extensive microstructural characterization to accurately understand the individual effects of twinning-induced plasticity (TWIP), transformation-induced plasticity (TRIP) and precipitation hardening on the mechanical properties of medium manganese steels. At the end of the project, four new third generation AHSS will be developed and a clear processing-microstructure-property relationship will be established. The commerciality of these materials will also be evaluated. The results from this work are expected to accelerate the design and discovery of new, high-performance and energy-saving materials. Ten highly qualified personnel (HQP), which consist of five graduate (two PhDs and three MScEs) and five undergraduate students are expected to join and strengthen the Canadian automotive and manufacturing industries. They are expected to support the research and development activities and maintain the competitiveness of Canadian industries.
加拿大政府和汽车行业定期审查政策、标准和法规,以确保司机和乘客的安全,并达到每年温室气体排放目标,从目前的704兆吨二氧化碳当量到2030年达到517兆吨二氧化碳当量。拟议的冶金研究计划旨在通过提高汽车的燃油效率来减少加拿大的温室气体排放,同时加强加拿大经济,通过开发一种新型,轻质,清洁和经济的第三代先进高强度钢(AHSS),使用非传统的合金概念,锰含量为8-10重量%。钢铁不是过时的材料。尽管开发了用于汽车部件的其他金属轻质材料,但在可预见的未来,白色车身的重要部件仍然并且将始终由钢制成。这是因为它的经济性,强度和耐用性的特殊组合。事实上,世界各地的钢铁行业都在积极开发下一代AHSS。该项目将分为四个主要阶段。第一阶段致力于合金设计,堆垛层错能(SFE)分析,热力学评估和新型AHSS的铸造。这些中锰钢将被设计为达到超过1000 MPa的拉伸强度和30- 40%的伸长率。第二阶段涉及这些钢的热处理和冷却循环,以建立平衡相变、冷却曲线和相图。第三阶段涉及实验室规模的热机械加工模拟,如热轧和热锻,以评估这些材料的可成形性。通过高速变形试验对耐撞性进行评价。第四阶段也是最后一阶段涵盖了广泛的微观结构表征,以准确了解孪晶诱导塑性(TRIP),相变诱导塑性(TRIP)和沉淀硬化对中锰钢机械性能的单独影响。在项目结束时,将开发四种新的第三代AHSS,并建立清晰的工艺-组织-性能关系。还将评价这些材料的商业性。这项工作的结果预计将加速设计和发现新的,高性能和节能材料。 十名高素质人员(HQP),其中包括五名研究生(两名博士和三名硕士)和五名本科生,预计将加入并加强加拿大汽车和制造业。预计它们将支持研究和开发活动,并保持加拿大工业的竞争力。
