Production and heat treatment of cast graphitic steels with additions of niobium
(2008-02-01)
The optimal combination of the mechanical characteristics of austempered spheroidal graphitic cast steel together with modern casting techniques yielded an economically promising product. The maximum potentiality of the ...
Structural aspects and mechanical properties induced by laser surface remelting of a tool steel
(Gordon Breach Sci Publ LtdReadingInglaterra, 1999)
Macro and microstructural characterisation of high Si cast steels–Study of microsegregation patterns
(Maney Publishing, 2016-11-23)
In this study the as-cast macro and microstructures of medium C – high Si cast steels of three different levels of alloying are characterised. The application of a colour-etching reagent sensitive to Si segregation effectively ...
Heat Treatment and Yb-Fiber Laser Welding of a Maraging Steel
(Amer Welding Soc, 2014-09-01)
Maraging steels are iron-nickel alloys having an unusual combination of high mechanical strength and high toughness. In this work, the effects of laser welding and postweld heat treatments have been analyzed. The fusion ...

Phase transformation in mechanically alloyed and hot-pressed Nb-4Si-8B and Nb-8Si-16B alloys
(2014-01-01)
The work reports on the phase transformation in mechanically alloyed and hot-pressed Nb-4Si-8B and Nb-8Si-16B (at-%) alloys. Elemental powder mixtures were processed in a planetary ball mill under argon atmosphere using ...
Superplasticidad de aceros de baja aleación con grano ultrafino: Superplasticity of ultrafine grained low-alloy steels
(Universidad de Montevideo, 2012)
Development of ultra-high strength carbide-free bainitic cast steels
(Maney Publishing, 2020-11)
High-silicon cast steels and proper heat treatment cycles were designed in order to obtain carbide-free bainitic microstructures. The design process allowed to obtain the desired microstructures after heat treatment cycles ...
Preparation and melting of Zr-1.0Nb alloy
(2016-01-01)
Zirconium alloys have many applications in industry in services too harsh for stainless steels, nickel alloys or where a noteworthy improvement in service life may be achieved, by choosing zirconium alloys instead of other ...
