The Crystal Structure of the Intermetallic Compound ZrZn22*
A complete determination of the crystal structure of the binary intermetallic compound most rich in zinc, the t-phase, in the zirconium-zinc system has been carried out with use of all intensity data obtainable from single crystal Weissenberg photographs taken with Cu Ka radiation. The composition of the completely ordered phase is ZrZn22. The refinement of the structure was carried out by appl...
متن کاملANALYTICAL DATA FOR NiO REDUCTION AND Al3Ni2 INTERMETALLIC COMPOUND FORMATION
In this research, the nickel oxide was dissolved in cryolite at temperatures of 880, 940 and 1000°C. In order to reduce the nickel oxide, aluminum was added to the salt. Simultaneously the nickel oxide was reduced and Al3Ni2 intermetallic compound was formed. In the duration intervals of 2.5-40 minutes samples of the salt and metallic phases were taken. The variation of the nickel content in me...
متن کاملIncreasing strength and conductivity of Cu alloy through abnormal plastic deformation of an intermetallic compound
The precipitation strengthening of Cu alloys inevitably accompanies lowering of their electric conductivity and ductility. We produced bulk Cu alloys arrayed with nanofibers of stiff intermetallic compound through a precipitation mechanism using conventional casting and heat treatment processes. We then successfully elongated these arrays of nanofibers in the bulk Cu alloys to 400% of original ...
متن کاملEffects of Grain Boundary Disorder on Yield Strength
It was recently reported that segregation of Zr to grain boundaries (GB) in nanocrystalline Cu can lead to the formation of disordered intergranular films [1,2]. In this study we employ atomistic computer simulations to study how the formation of these films affects the dislocation nucleation from the GBs. We found that full disorder of the grain boundary structure leads to the suppression of d...
متن کاملTwist-grain-boundary transitions in a chiral tolane compound
High resolution calorimetric studies have been carried out on the chiral compound methylheptyloxydi ̄ uorooctyloxybenzoyloxytolane (8BTF2O1M7 ). The tilt tendency is greater in this compound than in several other structurally similar ̄ uorinated tolane liquid crystals, and it exhibits tilted chiral smectic C (SmC*) and tilted twist-grain-boundary (TGBC) phases but not the untilted SmA or TGBA pha...
