气体是产生氢脆、发纹等缺陷的重要因素,显著降低钢的塑性和高温力学性能。精确地测定钛合金(钢)中的气体,是研试生产和提高广泛应用于航空、字宙航行等国防尖端工业中钛合金的关键。本文介绍采用国产仪器、仪表和真空器材自行设计并组装的真空熔融气相色谱仪。实验证明,此仪器完全可以满足生产和科研工作的需要。仪器的灵敏度:一氧化碳为0.1微升。特钢的分析误差由微压法
Gas is to produce hydrogen embrittlement, hair lines and other defects an important factor in significantly reducing the plasticity of steel and high temperature mechanical properties. Accurate determination of gases in titanium alloys is the key to researching and producing titanium alloys that are widely used in defense-critical industries such as aerospace and aerospace. This article describes the use of domestic instruments, instruments and vacuum equipment designed and assembled vacuum melting gas chromatograph. Experiments show that this instrument can fully meet the needs of production and research work. Instrument sensitivity: 0.1 μl of carbon monoxide. Special steel analysis error by the micro-pressure method
