The Ultrafine-Grained Titanium and Biomedical Titanium Alloys Processed by Severe Plastic Deformation (SPD)
the function of our tissues and organs. Among the biomedical materials, titanium alloys have received attractions for dental and orthopedic implants due to their high strength, great corrosion resistance and biocompatibility, and low density [1,2]. Recently, a series of new β titanium alloys have been developed with low elastic modulus, containing non-toxic alloying elements such as Nb, Ta, Zr ...
متن کاملMICROSTRUCTURE AND MECHANICAL PROPERTIES OF THE ULTRAFINE-GRAINED COPPER TUBE PRODUCED BY SEVERE PLASTIC DEFORMATION
In this paper, cyclic flaring and sinking (CFS) as a new severe plastic deformation (SPD) method was employed to produce the ultrafine grain (UFG) copper tubes. The extra friction has eliminated in the CFS method that provided the possibility for production of longer UFG tubes compared to the other SPD methods. This process was done periodically to apply more strain and consequently finer grain...
متن کاملNano- and Micro-mechanical Properties of Ultrafine-Grained Materials Processed by Severe Plastic Deformation Techniques
The processing of metals through the application of severe plastic deformation (SPD) techniques provides the potential for achieving exceptional grain refinement leading to ultrafine-grained (UFG) materials in bulk solids. These materials generally exhibit high strength but very limited ductility at room temperature (RT) leading to the so-called paradox of strength and ductility. The recent dev...
متن کاملZinc based bioalloys processed by severe plastic deformation – A review
Zinc based alloys have recently attracted great attention as promising biodegradable metals. Zinc exhibits moderate degradation rates in biological fluid and the zinc releases during the degradation process is considered safe to human systems. However, these materials exhibit critical limitations in terms of mechanical properties for medical applications. Adding alloying elements as well as gra...
متن کاملUsing differential scanning calorimetry as an analytical tool for ultrafine - grained metals processed by severe plastic deformation
Differential Scanning Calorimetry (DSC) is a thermal analysis technique that measures the energy absorbed or released by a sample as a function of temperature or time. Analysis by DSC has wide applications for examining solid-state reactions and solid-liquid reactions in many different materials. Quantitative analyses of the kinetics of reactions may be assessed by reviewing the interrelation b...
