“…The mass ratio of the material to the ball's mass is an important parameter for achieving the desired structure or grain size for the ground material. Thus, if this ratio is higher, the shorter the time required for milling, as the number of collisions increases at each instant and, consequently, increases the internal energy of the milling system [29,[30][31][32][33]. In Figure 6 it is observed that the particle size decreases with increasing milling time and with the ball mass ratio for grinding without addition of carbide.…”

“…As a general rule, it may be appreciated that the times taken to achieve steady-state conditions are short for high-energy mills and longer for low-energy mills. The increase of the milling time is characterized by the increase of the plastic deformation, generated by the impacts of the milled bodies, by which it leads to fracturing (due to the brittleness induced by the hulling) [4,20,[27][28][29][30][31][32].…”

The aim of this study was to provide an experimental investigation on the novel method for recycling chips of duplex stainless steel, with the addition of vanadium carbide, in order to produce metal/carbide composites from a high-energy mechanical milling process. Powders of duplex stainless steel with the addition of vanadium carbide were prepared by high-energy mechanical ball milling utilizing a planetary ball mill. For this proposal, experiments following a full factorial design with two replicates were planned, performed, and then analyzed. The four factors investigated in this study were rotation speed, milling time, powder to ball weight ratio and carbide percentage. For each factor, the experiments were conducted into two levels so that the internal behavior among them could be statistically estimated: 250 to 350 rpm for rotation speed, 10 to 50 h for milling time, 10:1 to 22:1 for powder to ball weight ratio, and 0 to 3% carbide percentage. In order to measure and characterize particle size, we utilized the analysis of particle size and a scanning electron microscopy. The results showed with the addition of carbide in the milling process cause an average of reduction in particle size when compared with the material without carbide added. All the four factors investigated in this study presented significant influence on the milling process of duplex stainless steel chips and the reduction of particle size. The statistical analysis showed that the addition of carbide in the process is the most influential factor, followed by the milling time, rotation speed and powder to ball weight ratio. Significant interaction effects among these factors were also identified.

“…However, there has still been a strong demand to recover indium (metal) from a waste material containing In. Recently, Zhang et al have reported on application of mechanochemical phenomena to recover useful materials from wastes [10][11][12][13] oxide (Ga 2 O 3 ) and Li 3 N under NH 3 , preparing GaN as a main product. This reaction seems to be non-thermal reduction of oxide through mechanochemical reaction with an aid of reducing agents.…”

“…* Corresponding author. Application of mechanochemical effect by a milling operation to induce mechanochemical effects such as phase transformation and solid state reaction is widely available in literature [7][8][9][10][11][12][13]. A process involving milling to effect MC reaction between CaWO 4 and magnesium to obtain W-metal is also reported [14,15].…”
