Study on combination of in-situ dispersion and secondary ...

2018-2-1  In addition, the secondary ball milling can increase the strain energy of the milled powders and extend the solid solubility of the alloy system. Consequently, sintering behavior of the materials can be altered and tends to be solid phase sintering. A fine microstructure with homogeneous distribution of the γ(Ni, Co) binder phase can therefore ...

Effect of ball milling process on the photocatalytic ...

2020-6-15  Abstract. CdS/TiO 2 composite photocatalysts were made by the method of secondary ball milling at different ball milling speeds, milling time, and material ratios. After the secondary ball milling process, parts of the samples were calcined at high temperatures. X-ray diffraction (XRD) and UV-Vis diffuse reflectance spectroscopy (DRS) were used to observe the powder particle size, structural ...

Study on characteristics and sintering behavior of W-Ni-Co ...

2018-1-15  Two different milling methods have been designed in this work and are named as “primary ball milling” and “secondary ball milling”, separately. The former is a standard milling procedure. The elemental powders of W, Ni, and Co with Y 2 O 3 particles were milled for 24 h. The latter is a secondary ball milling method.

Study of NiFeCoCr medium entropy alloy as a binder

Twinning structure of MEA binder phase is generated by secondary ball milling. Abstract. The binder phase of NiFeCoCr medium entropy alloy (MEA) dispersed in W–Mo heavy tungsten alloy synthesized by secondary ball milling was studied. The results show that the MEA binder phase with a single FCC solid solution structure was obtained after the ...

Study of NiFeCoCr medium entropy alloy as a binder

The subsequent secondary ball milling and sintering processes can lead to further interaction between the MEA binder phase and the W–Mo matrix phase. Furthermore, a large number of grains with a bright edge are observed in the microstructure (see Point “B”), which has a high concentration of W with a low content of Ni, Co, and Fe elements.
