Planetary Mills are ideally suited for fine grinding of hard, medium-hard, soft, brittle, tough and moist materials. The comminution of the material to be ground takes place primarily through the high-energy impact of grinding balls in rotating grinding bowls. The grinding can be performed dry, in suspension or in inert gas.
12%Other researchers also investigated the synthesis of high-nitrogen austenitic Fe–Cr–Ni–N [17, 18] and Fe–Cr–Mn–N [19,20,21,22] alloys through MA. From the above description, it is clear that it has not been possible to synthesize a homogeneous fcc austenite phase in Fe–Cr–Ni alloys unless the Ni content was at least 25 at.%.

The Cr-Cu-N coatings with various Cu contents (0–25.18 (±0.17) at.%) were deposited on Si wafer and stainless steel (SUS 304) substrates in reactive Ar+N 2 gas mixture by a hybrid coating system combining pulsed DC and RF magnetron sputtering techniques. The influence of Cu content on the coating composition, microstructure, and mechanical …
Cr 18.0 Mo 3.0 Ni 14.0 N 0.10 Table 1: Chemical composition of the work piece The grinding parameters selected for investigation are cutting speed (V s), feed rate (V f) and depth of cut (D). Each factor has three levels (process ranges). The other factors such as type of abrasive, workpiece, coolant, and spark out are constant.
These two types of mills are filled with varying compositions of grinding media. SAG mills contain balls of up to 150mm in diameter that occupy 5%-18% of mill chamber volume. Ball mills, conversely, contain grinding media up to 50mm in diameter, occupying between 25% – 40% of mill chamber volume.
Moreover, some HEAs with high Fe contents like Fe 34 Cr 34 Ni 14 Al 14 Co 4, Fe 36 Mn 21 Cr 18 Ni 15 Al 10 and Fe 55 (CrNiAl) 45 have shown such morphologies with better mechanical properties. In AlCoCrFeNi HEA systems, Al is a B2 phase stabilizer while Cr and Fe are A2 phase stabilizers.
The breakdown due to abrasion and clash of the milling balls made of 13% Cr white cast iron is a complicated process which depends on many factors, especially on …
The order would be for 250 tonnes of 5 inch forged steel grinding balls delivered in bags nominally containing 1 metric ton (or "tonne", representing 1, 000 KG or 2, 204.6 lb) of balls to the port of Montreal. One 20 foot container could load 25 …

A ternary phase with an approximate composition of (Cu, Cr) 4 Ti 3 was detected and named as τ 1.The three-phase equilibrium τ 1 + CuTi + Cu 4 Ti 3 was detected in the diffusion triple at a different grinding depth, as highlighted in the BSE image in Fig. 3(c). According to the trend of two phases tie-lines, Cu 3 Ti 2 phase was assumed to form a three …

An explanation on the formation of k-carbide and Cr 7 C 3 carbide is proposed.. The sintered alloy exhibits excellent hardness and …
Figure 11 shows the friction coefficients of Cr-Cu-N coatings with various Cu content against an [Al.sub.2][O.sub.3] ball on a ball-on-disk tribometer under a normal load of 2 N as a function of sliding distance at room temperature.
The powder mixtures were prepared by wet grinding in a ball mill in the conditions reported in . The content of FKh800 was varied from 25 to 40 wt.% in 5% steps. The samples were shaped in a closed die at a pressure of 800 MPa and sintered at 1100-1300°C in a vacuum electric furnace evacuated to at least 10 –2 Pa.
