“…A very impressive hardness value was reached (after ECAP route Bc for four passes) of 110 HV, along with an ultimate compressive strength of 185 MPa. The hardness observed in the ECAP-compacted alloy was mainly attributed to the dispersion hardening of Y 2 O 3 particles [7].…”

“…The ECAP process is a useful process for metallurgical studies of light alloys and especially for Mg, as shown by Ou et al [7], with the paper dealing with the Mg97Zn1Y2 alloy powders reinforced by Y 2 O 3 particles prepared by simultaneous synthesising of Y 2 O 3 particles and compacting of mechanically alloyed powders using equal channel angular pressing. They found that, after mechanical alloying for 20 h, the material consisted of α-Mg, Y and Y2O3 phases.…”

Titanium alloys are widely used in various industries such as aerospace, petrochemical, marine, and biomedical due to their high corrosion resistance, high strength, good heat resistance, and lightweight. However, the low thermal conductivity of titanium alloys makes their machinability poor compared to steel alloys. Therefore, it is of great importance to evaluate the machinability of titanium alloys. This experimental study presents the effects of machining parameters on the machinability factors such as surface roughness, power consumption, cutting sound, and machining force in dry turning of Ti-6Al-4V titanium alloy using CBN inserts. Sound emission is a substantial factor for the operator’s safety during the turning process. High cutting sound is generated due to removing a large amount of material from the workpiece using different cutting tools. Since there are not many studies related to the cutting sound in machining processes, the attempt was made to investigate the effect of cutting sound on the machinability factors. The variance analysis results presented the significant effect of cutting speed and cutting depth on power consumption. However, according to the normal plot of the standardized effect, all machining parameters have a high impact on the cutting sound. The highest level of machining parameters, especially cutting depth results in higher cutting sound due to the creation of vibration in the lathe and cutting tool. Besides, the feed rate was found to be the most influential parameter on the surface roughness with a 58.13% contribution. The machining force was affected by both cutting depth and feed rate. The findings revealed that increasing the cutting sound increases the machining force and surface roughness, while the power consumption drops. Based on the desirability function, 0.04 (mm/rev) feed rate, 0.05 (mm) cutting depth, and 60 (m/min) cutting speed were the optimum machining parameters for turning of Ti-6Al-4V titanium alloy.

“…It can be easily machined by the electrical discharge machining (EDM) and electrochemical machining (ECM) processes [2]. Since the ECM process may affect the top layer of the machined surface, EDM is normally utilized for machining such alloy [3]. It is a novel type of machining in which material is removed by applying regulated electrical pulses between the tool electrode and the workpiece specimen, as illustrated in Figure 1 [4,5].…”

Titanium alloy is widely used for orthodontic technology and easily machined using the EDM process. In the EDM process, the workpiece and tool electrode must be separated by a continuous air gap during the machining operation to generate discharge energy in this method. In the present study, an endeavor was made to analyze the effects of a servo feed air gap control and tool electrode in the EDM process. The developed mechanical setup consists of a linear action movement with zero backlash along the X-axis, which can be controlled up to 0.03 mm. It was observed that the suggested air gap control scheme can enhance the servo feed mechanism on a machining titanium alloy. A tungsten carbide electrode can enhance the surface measures owing to its ability to produce tiny craters with uniform distribution. Since it produces a little crater and has a higher melting point, a tungsten carbide electrode can create lesser surface roughness than a copper tool and brass tool electrode.
