Rapid solidification kinetics and mechanical property characteristics of Ni–Zr eutectic alloys processed under electromagnetic levitation state
TL;DR: In this article, a systematic analysis of the competitive growth mode between the primary phase and eutectic structure was conducted for three types of alloys (hypoeutective Ni-5 at.%Zr, eUTectic Ni-8.% Zr and hypereutectical Ni-13 at.%.

TL;DR: In this article, the orientation and interface characteristics of the Ni7Zr2 and Ni5Zr phases were investigated by electron backscatter diffraction (EBSD) and transmission electron microscopy (TEM).

The near-field acoustic levitation of high-mass rotors
TL;DR: It is demonstrated that spherical rotors with 40 mm diameter and 0-1 kg mass can be suspended more than tens of micrometers away from an ultrasonically vibrating concave surface by near-field acoustic radiation force.

Optimized Electromagnetic Fields Levitate Bulk Metallic Materials
X. Cai,HaiPeng Wang,P. Lü,B. Wei +3 more
TL;DR: In this article, an optimized solution based on finite element analysis (FEA) was developed to seek the best electromagnetic field distribution in the levitation zone, and two types of optimized coils were predicted by numerical simulations.

Peritectic solidification mechanism and accompanying microhardness enhancement of rapidly quenched Ni–Zr alloys
TL;DR: In this article, the effect of cooling rate on phase selection and microhardness of peritectic Ni-Zr alloys was investigated, and it was shown that cooling rate reaches 1.0"×"107"K/s, the growth of primary Ni7Zr2 and interdendritic eutectic Ni5Zr phases during the solidification of Ni-16.7" at.% Zr alloy melt is inhibited, and complete peritectical Ni5zr phase forms.
