Chipping Resistant Property of Nitrided Age-hardening Steels for Blanking Punches

Duplex Hardening of Steels for Aeroengine Bearings

Duplex hardening is a process in which conventional heat-treatments such as secondary or case hardening are followed up by surface nitriding to achieve exceptional properties, particularly in the context of aeroengine bearings. Hardness values in excess of 1 000 HV can in principle be achieved, and although the hardness decreases as a function of depth below the surface, some level of enhanceme...

Secondary Hardening in High Speed Steels

Neural-Network Analysis of Irradiation Hardening in Low-Activation Steels

An artificial neural network has been used to model the irradiation hardening of lowactivation ferritic/martensitic steels. The data used to create the model span a range of displacement damage of 0 90 dpa, within a temperature range of 273 973 K and contain 1800 points. The trained model has been able to capture the non-linear dependence of yield strength on the chemical composition and irradi...

From micro to nano scales -recent progress in the characterization of nitrided austenitic stainless steels

In the frontier of materials science, understanding of materials has been in multiple scales from macro, micro, to atomic levels. This is attributed to the advanced instrumentations such as SEM, TEM, XPS, XRD, as well as several other spectroscopic and metallographic analyses. Fe-CrNi based austenitic stainless steels have a diverse range of modern applications ranging from biomedical prosthese...
