“…The extent of microhardness profiles for titanium alloys is comparable with the extent of defect profile for Ti reported in this paper. There are also reports that increasing the cutting speed created higher hardness values [22].…”

“…The cutting speed was 47 m/min, the feed rate was 2 mm/s, and the depth of cut was 2 mm. The positron source of 22 Na was located between the machined surfaces of two samples, and such a sandwich was placed in front of the HpGe detector for measurement of the S-parameter. After that, the samples were etched in the solution of the nitric acid to remove a layer about 20 lm thick from the machined surfaces of the samples.…”

We demonstrate the application of the new experimental technique: positron probe microanalyser for studies of the defect profiles induced by milling. Metal foils of Cu, Fe and Ti were subjected to machining in a milling machine with different cutting speed. This technique revealed well-defined profiles of defects below the machined surface which was extended up to hundreds of micrometres. The extent of the profile depended on the metal and the cutting speed. The positron probe microanalyser allowed us to trace the evolution of the profile after annealing in different temperatures. Surprisingly, the high thermal stability of a few tens of micrometres thick layer adjacent to the machined surface was detected.

“…Many studies have been conducted to investigate the surface integrity of titanium alloys, including Ti-6Al-4V, Ti-6242S, and Ti-6246 [7][8][9][10][11][12][13]. Sun and Guo [8] reported that roughness is obviously influenced by cutting speed and tool wear.…”

“…Consequently, the machined surface tends to become smooth toward the end of tool life at a cutting speed of 60 m min −1 . Other researchers have reported that cutting speed [7,[9][10][11]15] is effective to a certain degree in increasing surface roughness. As cutting speed is increased, surface roughness Y. Houchuan : C. Zhitong : Z. ZiTong increases for Ti-6246 and Ti-64 [7,8,13,14].…”

This study focuses on the machined surface integrity of the titanium alloy Ti-10V-2Fe-3Al (Ti-1023) during face milling. Surface roughness, machining defect, microhardness, and microstructure variations are investigated at different cutting speeds and tool average flank wear (VB) values. Experimental results show that surface roughness increases when cutting speed is increased from 40 to 100 m min −1 and decreases when cutting speed is increased from 100 to 300 m min −1 by using a new tool. Moreover, surface roughness values are stable when cutting speed is increased by using a worn tool at VB =0.2 mm and increases when VB is increased. As for defects, the machining defect is determined to be dependent on cutting speed and tool wear directions. Microhardness is decreased to 35 μm beneath the machined surface at different cutting speeds by using a new tool. The influence of tool wear on hardening is significant, with the depth of hardening being less than 55 μm by using a worn tool at VB=0.2 mm and reaching 130 μm at VB=0.35 mm. No significant phase transformation or evident deformation can be observed at different cutting speeds by using a new tool (initial wear). Severe plastic deformation and deep alteration of the microstructure in the machined surface are produced with VB from initial wear to VB=0.35 mm. VB is best maintained at less than 0.2 mm for finish machining of Ti-1023.
