The effect of rare earth (RE) elements, including Ce and La, on the sorption properties of Zr-Co getters was investigated in this work. The phase evolution, microstructural characteristics of getter powders were studied by means of X-ray diffraction method, scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDS). The nanostructured Zr3Co intermetallic compound has been...

magnesium is potentially useful for orthopedic and cardiovascular applications. magnesium and its alloys are light, biodegradable, biocompatible metals that have promising applications as biomaterials. however, the corrosion rate of this metal is so high that its degradation occurs before the end of the healing process. one of the ways to improve the corrosion rate is to compose it with ceramic...

nowadays, titanium-based alloys are among the most attractive metallic materials for biomedical applications (as implants) due to their non-biodegradability, low density, good mechanical properties as well as their good biocompatibility. hydroxyapatite (ca10 (po4)6(oh)2, ha) has been widely used for biomedical applications due to its bioactive, biocompatible and osteoconductive properties. firs...

titanium aluminide and its alloys have been utilized in automotive, aerospace and power industries because of their specific properties such as low density (~ 4 g/cm3), high melting temperature (~ 1460 °c) and excellent high-temperature strength. ti-48al intermetallic compound and its alloys with 1.5, 3 and 5 at.%mn were produced with mechanical alloying of elemental powders for 50 hours. the p...

In this work, iron-doped SnO2 powders were prepared by two methods: mechanical alloying and mechanochemical alloying with successive thermal treatment. The influence of different milling conditions such as ball to powder weight ratio, milling time, rotation velocity of supporting disc and the type of iron starting reactive and their Fe concentration on the structural and magnetic properties of ...
