Alloys containing molybdenum (7 wt% and 10 wt%) and zirconium (2 wt%, 5 wt%, and 10 wt%) were fabricated and homogenized at °C. They were then subjected to annealing at °C for periods of 1, 2, and 5 hours in order to study phase characteristics.

In this work, three Zr microalloyed steels with different levels of Zr were compared with plain C-Mn, Nb and Nb-Ti steels. Austenitic grain size was compared as a function of temperature for these steels. A qualitative assessment of the potential of Zr to delay austenite recrystallization, was also undertaken. Of course, the actual use of Zr depends on many considerations: cost, availability Cited by: 3.

Neutron and X-ray diffraction is a very powerful tool in texture analysis of zirconium base alloys used in nuclear technique [1]. Textures of five samples (labeled as ZZ13, ZZ14, ZZ19, ZZ16 and ZZ17) were investigated by using pole figures and inverse pole figures. Z.E.

An x-ray spectrographic method has been developed for routine analysis of mixtures of zirconium and hafnium oxides in the range of concentrations from to percent hafnium in zirconium. The method makes use of the newly perfected x-ray fluorescence analysis equipment incorporating a Geiger tube together with associated scaling and recording circuits for measurment of intensities.

The stable intermetallic particles may undergo structural changes dependent on their composition and the temperature. For the metastable dual-phase α/β-alloys (ZrNb alloy), the β-phase structure is modified during irradiation, but the change is complex, being a combination of thermal decomposition and radiation-induced by: Effect of heavy ion irradiation on microstructure and electron density distribution of zirconium alloy characterised by X-ray diffraction techniquejee and Variable Energy Cyclotron Centre, 1/AF Bidhannagar, Kolkata –India.

Abstract.Almost 75% of all niobium metal is used as minor alloying additions in low-alloy steel. Another 20 to 25% is used as alloy additions in nickel-base superalloys and heat-resisting steels.

Only 1 to 2% of all niobium is used in the form of niobium-base alloys and pure niobium metal including superconducting niobium-titanium alloy, which accounts.
