Nylon 6 is a widely used engineering polymer, and has relatively poor impact strength. Ethylene, n-Butyl acrylate, maleic anhydride (E-nBA-MAH) terpolymer is blended with Nylon 6 to enhance its impact strength. Mixture should be compatible to be used in applications. The bare interaction energy between Nylon 6 and E-nBA-MAH terpolymer is calculated according to melting point depression approach using both Flory-Huggins (FH) Theory and Sanchez-Lacombe Equation of State (SL EOS). It demonstrates that blends are thermodynamically favorable to any arrangements. Yet, isothermal crystallization kinetics and WAXS crystallization peaks of blends reveal that mixtures of various compositions have different crystallization behaviors and require alternating crystallization energy due to crystalline structures of individual polymers. Also, SEM images support that after 5% addition of elastomeric terpolymer, interaction loosens due to strong crystalline structure of Nylon 6.

Efficient fabrication of ultrafine-grained 316L stainless steel surfaces for orthopaedic applications Tufan, Yiğithan; Efe, Mert; Ercan, Batur (Informa UK Limited, 2019-10-13) Commonly used severe plastic deformation (SPD) methods are suitable for fabrication of bulk nano and ultrafine-grained metals. Drawbacks of these methods include durability of dies, geometrical restrictions and reduced ductility of the products. In this study, two common machining techniques used in manufacturing of orthopaedic components, turning and milling, were applied on 316L stainless steel as surface SPD to refine the surface microstructures of the workpiece. Machining with optimised parameters resul...
Titanium-magnesium based composites: Mechanical properties and in-vitro corrosion response in Ringer's solution ESEN, ZİYA; Dikici, Burak; Duygulu, Ozgur; Dericioğlu, Arcan Fehmi (Elsevier BV, 2013-06-20) Ti-Mg composite rods exhibiting both bioinert and biodegradable characteristics have been manufactured by hot rotary swaging from elemental powders of titanium and magnesium. As a result of processing, spherical magnesium powders elongated in the direction of deformation and the dendritic structure in starting magnesium powders transformed into highly equiaxed grains. Magnesium particles in the outer layer of the composites were decorated by thin layer of MgO while the interior parts were free from oxides. ...
Fabrication of micropit structures on Ti6Al4V alloy using fluoride-free anodization for orthopedic applications Izmir, Merve; Ercan, Batur (Cambridge University Press (CUP), 2019-04-15) Ti6Al4V alloy is commonly used in hip and knee replacements due to its high strength, ductility, wear, and corrosion resistance. Despite its optimal physical and chemical properties, Ti6Al4V based orthopedic implants have a limited lifetime of only 15-20 years. One of the main reasons for having limited lifetime is the suboptimal integration of Ti6Al4V implants with the juxtaposed bone tissue (osseointegration). To enhance osseointegration, and thus prolong the lifetime of orthopedic implants, Ti6Al4V impla...
Effect of High-Density Nanoparticles on Recrystallization and Texture Evolution in Ferritic Alloys Aydoğan Güngör, Eda; Carvajal-Nunez, Ursula; Vogel, Sven C.; Li, Meimei; Maloy, Stuart A. (MDPI AG, 2019-03-01) Ferritic alloys are important for nuclear reactor applications due to their microstructural stability, corrosion resistance, and favorable mechanical properties. Nanostructured ferritic alloys having a high density of Y-Ti-O rich nano-oxides (NOs < 5 nm) are found to be extremely stable at high temperatures up to similar to 1100 degrees C. This study serves to understand the effect of a high density of nano-particles on texture evolution and recrystallization mechanisms in ferritic alloys of 14YWT (14Cr-3W-...
Investigating the effects of hardening of aluminium alloys on equal-channel angular pressing-A finite-element study Karpuz, P.; Simsir, C.; Gür, Cemil Hakan (Elsevier BV, 2009-03-15) Equal-channel angular pressing (ECAP) is a promising severe plastic deformation method for production of ultrafine-grained bulk metals and alloys with considerably improved mechanical properties. In this study, numerical experiments were carried out to investigate the effect of strain hardening of aluminum alloys on the process performance of ECAP via finite element modeling. In the constitutive model, isothermal-plane strain, frictionless condition was assumed. The numerical results showed that strain hard...
