Rare-earth- and aluminum-free, high strength dilute magnesium alloy for Biomedical Applications

Autor: Md Ershadul Alam, Soupitak Pal, Ray Decker, Nicholas C. Ferreri, Marko Knezevic, Irene. J. Beyerlein

Publikováno v: Scientific Reports, Vol 10, Iss 1, Pp 1-15 (2020)

Abstract Lightweight, recyclable, and plentiful Mg alloys are receiving increased attention due to an exceptional combination of strength and ductility not possible from pure Mg. Yet, due to their alloying elements, such as rare-earths or aluminum, t

Effects of heat treatment and build orientation on the evolution of ϵ and α′ martensite and strength during compressive loading of additively manufactured 304L stainless steel

Autor: Veronica Livescu, M. A. Torrez, George T. Gray, Donald W. Brown, Jun-Sang Park, Marko Knezevic, Nicholas C. Ferreri, Reeju Pokharel

Publikováno v: Acta Materialia. 195:59-70

The effect of heat-treatment and build orientation on martensitic phase transformation in additively manufactured (AM) 304L stainless steel is studied and compared with conventionally produced wrought material. The relationships between observed mart

Strain-Rate Sensitivity, Tension-Compression Asymmetry, r-Ratio, Twinning, and Texture Evolution of a Rolled Magnesium Alloy Mg-1.3Zn-0.4Ca-0.4Mn

Autor: Marko Knezevic, Irene J. Beyerlein, Ray Decker, Evgenii Vasilev, Nicholas C. Ferreri

Publikováno v: Metallurgical and Materials Transactions A. 51:3858-3868

In this work, the deformation response, texture evolution, and twinning development of a magnesium (Mg) alloy, Mg-1.3Zn-0.4Ca-0.4Mn, for biocompatible applications are investigated. Further, the alloy’s formability, by examining the instantaneous r

Experimental characterization and crystal plasticity modeling of anisotropy, tension-compression asymmetry, and texture evolution of additively manufactured Inconel 718 at room and elevated temperatures

Autor: Anil Kumar, Marko Knezevic, Saeede Ghorbanpour, Nicholas C. Ferreri, Ershadul Alam, Sven C. Vogel, Jonathan Bicknell, Brandon McWilliams, Irene J. Beyerlein

Publikováno v: International Journal of Plasticity. 125:63-79

In this work, strength and microstructural evolution of superalloy Inconel 718 (IN718) are characterized as a function of the initial microstructure created via direct metal laser melting (DMLM) additive manufacturing (AM) technology along with subse

Role of grain structure, grain boundaries, crystallographic texture, precipitates, and porosity on fatigue behavior of Inconel 718 at room and elevated temperatures

Autor: Jonathan Bicknell, Marko Knezevic, Sean Gribbin, Saeede Ghorbanpour, Nicholas C. Ferreri, Igor Tsukrov

Publikováno v: Materials Characterization. 149:184-197

This paper presents the main results from an investigation into the effect of initial microstructure on high cycle fatigue behavior of Inconel 718 superalloy. To create a variety of initial microstructures, the material was deposited at a 45° (diago
