  • Micro-Alloyed Steel for Forgings
    Materials Science Forum, 2018
    Co-Authors: Sabrina Mengaroni, Chiara Zitelli, Giuseppe Napoli, M. Calderini, Andrea Di Schino
    Abstract:

    To fulfill the industrial demand of Forged steels with high tensile properties and microstructural requirements coupled with reduced cost, the possibility to increase the properties of C-Mn steels by means of precipitation strengthening as achieved by micro-alloying (and without the addition of expensive elements such as Mo and Cr) has been evaluated. In order to do that, the effect of V addition has been exploited by means of metallurgical modelling followed by a laboratory ingot manufacturing. Heat treatment has been designed aimed to achieve the desired target tensile properties. Results show that ASTM A694 F70 grade requirements can bel fulfilled by 0.15% V addition and a proper heat treatment in a ferrite-pearlite microstructure, representative of a Forged Component. Results are discussed in comparison to those of a similar steel without V addition.

    International Journal of Microstructure and Materials Properties, 2016
    Co-Authors: Chiara Zitelli, Giuseppe Napoli, Sabrina Mengaroni, Dario Venditti, Andrea Di Schino
    Abstract:

    The aim of the present paper deals with the production of heavy steel forgings of micro-alloyed steels.

The effect of vanadium addition has been assessed by means of metallurgical modelling step followed by a laboratory demonstration phase by means of ingot manufacturing. Heat treatment has been designed aimed to achieve the desired target tensile properties. Results show that ASTM A694 F70 grade requirements can be fulfilled by 0.15% V addition and a proper heat treatment in a ferrite-pearlite microstructure, representative of a Forged Component.

  • X-ray CT assisted damage identification in warm forging
    'Elsevier BV', 2018
    Co-Authors: Lc Chan
    Abstract:

    17th International Conference on Metal Forming, METAL FORMING 2018, Japan, 16-19 September 2018This study aims to identify the 3-dimensional interactions of micro-voids evolution before and after warm-forging a typical titanium alloy Component by employing a micro-focus X-ray CT system so as to achieve a more accurate micro-void location and distribution as critical data input for damage prediction in warm forging. A specific forging tool was designed for warm-forging the Component. Serval local regions that represented different strain levels were established as representative volume element models for the Ti-6Al-4V preform, in which, the micro-void distributions were obtained directly from the X-ray CT images. Furthermore, the micro-void evolutions of the corresponding representative volume element models were analyzed from the Forged Component. Thus, the damage evolution, i.e., the variation of void volume fraction, in the warm forging process was identified.Department of Building and Real Estate201906 bcmapublished_fina
