Retained austenite analysis

Steels and steel alloys are an essential component in many everyday applications. Quality control is crucial to maintaining the structural stability of these materials. During the processing of these heat-treated steel alloys, austenite may be retained which could weaken the overall structural integrity of the material used to build our buildings, cars, bridges and much more. In this experiment retained austenite analysis was performed on a typical metal sample. The retained austenite phase was identified in the pattern below, taken with Rigaku's MiniFlex benchtop diffractometer, in a 5.9(0.1)% concentration. The analysis shown was performed using Jade's Whole Pattern Fitting (WPF) program.

The fifth generation MiniFlex is a general purpose X-ray diffractometer that can perform qualitative and quantitative analysis of polycrystalline materials. The MiniFlex is available in two variations. Operating at 600 watts (X-ray tube), the MiniFlex 600 is twice as powerful as other benchtop models, enabling faster analysis and improved overall throughput. Running at 300 watts (X-ray tube), the new MiniFlex 300 does not require an external heat exchanger. Each model is engineered to maximize flexibility in a benchtop package. Read more...
