The Aerospace industry utilizes high strength steels for landing gear components. When the strength of the steel is very high, it becomes vulnerable to embrittlemnt phenomena caused by impurities, carbon and hydrogen intake from the environment. The aim of this work is to understand how the processing of landing gears (e.g. cooling rate and shot-peening) affect the carbon and hydrogen distribution in the steel and how these, in turn, affect the steel's vulnerability to embrittlement. The work is supported by UTAS (Landing Gear Division), which is a world leader in the Aerospace Industry and is part of the company's commitment to highest levels of safety and excellence.

航空航天工业使用高强度钢作为起落架部件。当钢的强度很高时，容易受到杂质、从环境中摄取的碳、氢等引起的脆化现象的影响。这项工作的目的是了解起落架的加工（例如冷却速度和喷丸处理）如何影响钢中的碳和氢分布，以及这些如何反过来影响钢的脆性。这项工作得到了UTAS（起落架部门）的支持，UTAS是航空航天工业的世界领导者，也是公司对最高安全和卓越水平承诺的一部分。
