Oil wells operate in very hostile environments with hydrogen being an extremely deleterious component. This is because only a few parts per million of hydrogen can cause fracture that is not only premature but also unpredictable; this obviously poses a very serious risk to public safety and the environment. Currently, steels require expensive alloying additions and time-consuming processing to provide strong resistance to hydrogen damage. Niobium is a possible alloying element that has the potential to improve the resistance to hydrogen embrittlement (HE), but at considerably lower concentrations compared to the currently used alloying elements, thus affording significant cost reductions. This partnership of this proposal comprises a steel manufacturer, EVRAZ, a government laboratory, CANMETMaterials, and McGill University. The ultimate goal of this partnership is to enable EVRAZ to produce new, higher strength and HE resistant steels to be used in the oil and gas industry. This particular proposal will generate a basic understanding of the effect of alloying and microstructure on HE susceptibility, focussing on niobium additions. The findings will be used to design steels and the corresponding processing (hot rolling and heat treatment) schedules that will be used in industry. These steels and the processes will be investigated in the next alliance grant between the same partners performing the same roles, culminating in industrial steelmaking and processing trials at EVRAZ, and HE susceptibility analyses at McGill. EVRAZ will commercialize the steels using their own internal practices.This work can actually have far reaching effects in many other sectors because HE is a problem anywhere there are load bearing applications. Thus, the considerable of body fundamental knowledge that will be generated in this project can be applied to automotive, energy and civil engineering sectors, all of vital importance to the Canadian economy and infrastructure. Finally, the research will be conducted mainly by graduate students at McGill University who will be trained in advanced steel alloy design, processing and characterisation. These high quality personnel will add greatly to the high tech Canadian work force.

油井在非常敌对的环境中运行，氢是极其有害的组成部分。 这是因为只有每百万氢的少数少数少数零件会导致不仅过早而且不可预测的裂缝。这显然对公共安全和环境构成了非常严重的风险。 当前，钢需要昂贵的合金添加和耗时的加工，以提供对氢损害的强烈抗性。 Niobium是一种可能的合金元素，具有提高对氢的抗抑制性（HE）的潜力，但与当前使用的合金元素相比，浓度较低，从而大大降低了成本。该提案的这种合作伙伴关系包括钢铁制造商Evraz，政府实验室，Canmetmaterials和McGill University。 这种合作伙伴关系的最终目标是使Evraz能够产生新的，更高的力量，并且他的抵抗力可以用于石油和天然气行业。 该特定建议将产生对合金和微结构对HE敏感性的影响的基本理解，重点关注尼伯族的添加。这些发现将用于设计钢和将在行业中使用的相应处理（热滚动和热处理）。 这些钢和过程将在下一个联盟赠款中进行调查，同一合作伙伴扮演相同的角色，最终在Evraz的工业钢制和加工试验中进行，并在McGill进行了敏感性分析。 Evraz将使用自己的内部实践将钢化商业化。这项工作实际上在许多其他领域都可以产生远距离影响，因为他在任何有负载轴承应用的地方都是问题。 因此，该项目将产生的人体基本知识可用于汽车，能源和土木工程领域，这对于加拿大的经济和基础设施至关重要。 最后，这项研究将主要由麦吉尔大学的研究生进行，他们将接受高级钢合金设计，加工和特征的培训。 这些高质量的人员将极大地增加加拿大高科技的劳动力。
