Procedure for selecting appropriate steels for machine design [PDF]

open access: yes, 2010
Selection of steels for industrial purposes usually means choosing a type of steel to make a part or a product. The steel that is chosen must meet all the designer requirements. A quantitative selection procedure has been used to analyze the large amount

Processes, microstructure and properties of vanadium microalloyed steels [PDF]

open access: yes, 2009
Vanadium as an important alloying element in steels was initially associated with the properties achieved following tempering. Interest in the microstructure was stimulated by the advent of transmission electron microscopes with a resolution of ~1nm ...

Evolution of precipitates, in particular cruciform and cuboid particles, during simulated direct charging of thin slab cast vanadium microalloyed steels [PDF]

open access: yes, 2004
A study has been undertaken of four vanadium based steels which have been processed by a simulated direct charging route using processing parameters typical of thin slab casting, where the cast product has a thickness of 50 to 80mm ( in this study 50 mm)

Nitriding of aluminium-containing steels [PDF]

open access: yes, 1984
This thesis describes a study of the nitriding behaviour of some aluminium-containing low alloy steels with and without chromium. The main aim of the study has been to establish the relationship between prior heat treatment and nitriding process ...

Use of the small punch test for the estimation of ductile-to-brittle transition temperature shift of irradiated steels

open access: yesNuclear Materials and Energy, 2021
The small punch test is evaluated as a screening procedure for irradiation embrittlement of reactor pressure vessel steels. In particular, the correlation between ductile-to-brittle transition temperatures obtained from this small specimen test technique
