Journal ArticleDOI

Mechanical behavior of amorphous alloys

Christopher A. Schuh, +2 more
- 01 Jul 2007 - 
TL;DR: In this paper, a review of recent advances in understanding the mechanical behavior of metallic glasses, with particular emphasis on the deformation and fracture mechanisms, is presented, where the role of glass structure on mechanical properties, and conversely, the effect of deformation upon glass structure, are also described.
Journal ArticleDOI

Mechanical behavior of selective laser melted 316L stainless steel

Jyoti Suryawanshi, +3 more
- 01 Jun 2017 - 
TL;DR: In this article, the tensile, fracture, and fatigue crack growth properties of 316L stainless steel (SS) produced using the selective laser melting (SLM) technique were evaluated and compared with those of conventionally manufactured (CM) austenitic SSs.
Journal ArticleDOI

Simultaneous enhancements of strength and toughness in an Al-12Si alloy synthesized using selective laser melting

Jyoti Suryawanshi, +7 more
- 15 Aug 2016 - 
TL;DR: In this paper, the effect of laser track direction on quasi-static tensile, fracture, fatigue crack growth, and unnotched fatigue properties was examined and the results were compared with those obtained on specimens produced through the conventional casting route.
Journal ArticleDOI

Embrittlement of a bulk metallic glass due to sub-Tg annealing

P. Murali, +1 more
- 01 Mar 2005 - 
TL;DR: In this paper, the authors investigated the susceptibility of bulk metallic glass (BMG) to embrittlement upon annealing at temperatures below its glass transition temperature, and found that the reduction of free volume due to annaling is the primary mechanism responsible for the loss in toughness.
Journal ArticleDOI

Microstructural effects on the mechanical behavior of B-modified Ti–6Al–4V alloys

Indrani Sen, +3 more
- 01 Sep 2007 - 
TL;DR: In this paper, microstructural properties of hot isostatically pressed Ti-6Al-4V alloy with 0, 0.05, 0., 10, and 0.40 wt.% B additions have been examined, with particular emphasis on identifying the micro-structural length scale (grain size vs. lath size) that controls the mechanical properties of these alloys.
