Theoretical design of ferritic creep resistant steels using neural network, kinetic, and thermodynamic models
Creep resistant ferritic steels based on Fe–2·25Cr–1Mo and Fe–(9–12)Cr have been used extensively in the energy and petrochemical industries for more than half a century. This is because they have an outstanding record of reliability in quite aggressive conditions over time periods as long as 30 years. The alloys have undergone progressive development throughout their history,1,2 particularly i...
متن کاملTowards Self-healing Creep Resistant Steels
We report the main findings of our work on the behaviour of binary Fe-Cu and Fe-Au model alloys designed to explore routes to create new creep resistant steels having an in-built ability to autonomously fill creep induced porosity at grain boundaries. The alloying elements were selected on the basis of their ability to be brought in supersaturation, their limited or even absent tendency to form...

متن کاملNeural network model of creep strength of austenitic stainless steels
The creep rupture life and rupture strength of austenitic stainless steels have been expressed as functions of chemical composition, test conditions, stabilisation ratio, and solution treatment temperature . The method involved a neural network analysis of a vast and general database assembled from published data. The outputs of the model have been assessed against known metallurgical trends an...
متن کاملFundamental Principles of Heat - Treating Steels
eat-treating is a process that is critical to the fabrication of steel fasteners. It is a necessary process in order to achieve the mechanical properties. Heat-treating is typically conduc t ed a f t e r t he fo rming processes and before any coating or finishing processes. Heat-treating may be done by the manufacturer or outsourced to a commercial shop. The equipment necessary to effect ively ...
