Also, the CNTs were pre-coated to improve the agglomeration of the CNTs with copper powder. The main aim of this work is the fabrication of Cu-CNT nanocomposite powder using the MA by ball milling. The as-received dendritic copper powders change their shape sequentially to flaky, disk-typed particles and finally, to globular type particles

The deformation structures of copper powder induced by ball milling were studied in detail by using high resolution electron microscopy. It was found that copper powder after 20 h of milling shows the formation of shear bands and a number of mechanical twins. The observed twins belong to two types, i.e. multiple twins and high-order ones. It is suggested that Venables' model on mechanical

Feb 18, 2021 This paper reports on the structural and magnetic properties of a ball-milled powder sample of (Fe 1−x Mn x) 75 P 15 C 10 (x = 0, 0.05, 0.1, 0.2, and 0.3) mixed metallic amorphous ribbons. X-ray diffraction patterns of the as-made powder samples demonstrate a structural phase transition from amorphous to the nanocrystalline structure having a tetragonal (P) type structure

Nov 01, 2019 In addition, the copper powder was also milled for comparison. Tungsten carbide lined vials and balls were used for milling and a ball to powder ratio of 10:1 was used for all the mixtures. The ball milling was performed in toluene medium with a rotation speed of 300 rpm using a Fritsch Pulverisette 5 planetary ball mill

WC, WC-10%wtCu and WC-30%wtCu powder batches were milled in a planetary ball mill at the milling speed of 400rpm for 20h in argon atmosphere. The ball to powder weight ratio was 15:1. The milling vessels and balls were made of tungsten carbide. The milled powders were cold pressed at 100,200,300 and 400 MPa in a 13mm diameter cylindrical die. The
