“…However, nearly no Ti-b phase peaks could be discerned on the punch surface after test. This observation is consistent with data previously reported by Sauger and Blanchard on TTS formation [3,5]. Indeed, on their comparative study on the tribologically induced transformation of TA6V and TV15CA(b), those authors have pointed out evidences of Ti texturing under fretting and occurrences of phase transformation from b to a. Secondly, the appearance of a new structure is of great interest.…”

“…Early in the 1980s, Hamdy and Waterhouse reported the formation of a glaze layer at elevated temperature on Ti-6Al-4V [2]. Later, Blanchard et al [3] and Fayeulle et al [4], focussed their studies on the transformation of Ti alloys under fretting. They reported the presence, at the surface of the mated parts, of a nanocrystalline structure characterized by a composition corresponding to that of the bulk material and an increased hardness.…”

The present investigation focuses on the tribological transformation occurring on a Ti alloy (Ti17) under fretting in air. Several fretting wear tests were performed on a large scale punch on plane configuration (two types of planes tested: bare Ti6242 and CuNiIn-coated Ti6242) at several temperatures from ambient up to 450°C. In all the cases, two zones were identified on the scars: a lateral oxidized rim and a highly deformed region at centre. Metallurgical observations revealed similarities with Tribologically Transformed Structure (TTS), previously observed on various Ti alloys. In the framework of this article, careful analyses were conducted (EDX, DRX, XPS, HRTEM and EFTEM) in order to identify the nature and chemistry of this transformed layer. Results demonstrated the formation of a new phase, nanocrystalline, identified as TiO x N y . The high content of nitrogen found in the TTS indicated its ability to penetrate inside the contact and react with titanium. At 50 lm under the surface, a FIB preparation enabled the observation in TEM of N-rich lamellae (TiO x N y ) in the Ti (a) matrix. Two models were suggested to explain this tribochemical reaction under fretting.

“…Results for the low clamping stress condition are higher than for the high clamping stress condition. This finding is not entirely unexpected, since lower clamping stresses allow greater freedom of motion, and with greater motion comes greater wear [4,21,22]. At low clamping stress and 100%-of-life, however, the data coincide with the high clamping stress data for high spatial frequencies (>3 |im).…”

A new synthesis technique, namely double mechanical alloying (dMA), has been developed to fabricate aluminum alloys containing the finely distributed intermetallic compounds and inert dispersoids Al 4 C 3 and AIP3' The technique consists mainly of three steps: a primary milling stage of elemental powders (MAl) followed by a heat treatment to promote the formation of intermetallic phases, a secondary milling stage (MA2) to refine the microstructure, and consolidation of the produced powders. The results of mechanical and tribological properties of the resulting materials indicate that the dMA is a promising technique for the fabrication of aluminum alloys for applications requiring wear resistance and high-temperature performance.
