Abstract

- The effect of cycling on titanium nitride stability in a range of normalized steels containing additions of V, Al, and N has been investigated. Nitride dispersions and chemical analysis of individual particles are studied using transmission electron microscopy and a quantitative 200 kV STEM-EDX-EELS microanalysis system. Whereas normalized material contains nitrides of mixed compositions, only nitrides based on TiN survive high energy simulated weld cycles. Grain growth is dependent on stability, and this depends on the original composition of the nitrides. The presence of aluminum is particularly detrimental. The best gain growth control and highest toughness are found in steels based on optimum ratios of Ti/V/N and on low Al levels
