Journal ArticleDOI
The metallurgy and processing science of metal additive manufacturing
TL;DR: In this article, a review of additive manufacturing (AM) techniques for producing metal parts are explored, with a focus on the science of metal AM: processing defects, heat transfer, solidification, solid-state precipitation, mechanical properties and post-processing metallurgy.
Journal ArticleDOI
Site specific control of crystallographic grain orientation through electron beam additive manufacturing
Ryan R. Dehoff,Michael M. Kirka,William J. Sames,Hassina Z. Bilheux,Anton S. Tremsin,Larry E Lowe,S. Suresh Babu +6 more
TL;DR: In this paper, columnar to equiaxed transitions during solidification were used to promote the growth of highly misoriented micron scale grains outlining the letters D, O and E, through the thickness of a 25·4 mm tall bulk block comprised of primarily columnar oriented grains made of the nickel base superalloy Inconel 718.
Journal ArticleDOI
Numerical modeling of heat-transfer and the influence of process parameters on tailoring the grain morphology of IN718 in electron beam additive manufacturing ☆
Narendran Raghavan,Ryan R. Dehoff,Sreekanth Pannala,Srdjan Simunovic,Michael M. Kirka,John A. Turner,Neil N. Carlson,S. Suresh Babu,S. Suresh Babu +8 more
TL;DR: In this article, the authors developed a melt scan strategy for electron beam melting of nickel-base superalloy (Inconel 718) and also analyzed 3-D heat transfer conditions using a parallel numerical solidification code (Truchas) developed at Los Alamos National Laboratory.
Journal ArticleDOI
Atomic scale observations of bainite transformation in a high carbon high silicon steel
TL;DR: In this paper, a fine-scale bainitic microstructure with high strength and high toughness has been achieved by transforming austenite at 200°C. X-ray diffraction analysis showed the carbon concentration of these bainite ferrite plates to be higher than expected from para-equilibrium.
Journal ArticleDOI
Wintertime aerosol characteristics over the Indo‐Gangetic Plain (IGP): Impacts of local boundary layer processes and long‐range transport
Vijayakumar S. Nair,K. Krishna Moorthy,Denny P. Alappattu,P. K. Kunhikrishnan,Susan K. George,Prabha R. Nair,S. Suresh Babu,B. Abish,Sathianeson Satheesh,Sachchida Nand Tripathi,K. Niranjan,B. L. Madhavan,V. Srikant,C. B. S. Dutt,K. V. S. Badarinath,R. Ramakrishna Reddy +15 more
TL;DR: In this article, the authors investigated the effects of mesoscale processes associated with changes in the local atmospheric boundary layer (ABL), and examined the changes as the season changes over to spring and summer.
