The first successful trial of RUM process as an ultrasonic milling was carried out by Pei et al. [5] in 1994.
Hu, et al. [6] studied the RUM process with different rotational speeds (1000 up to 3000 rpm) and observed no significant effect of varying speeds on the MRR.
The different cutting depth (10-50 mm) and different feed rate (100-500 mm/min) have also been studied by Lauwers et al. [8].

Peguet et al. [19] reported that the maximum pit initiation occurs at 20% cold reduction for 304 type stainless steels.
Rockel et al. [37] and Felloni et al. [36] have attributed the formation of the second peak in the polarization curve to Ni enrichment/H2 oxidation and Ruel et al. [35] claimed that dissolution of Cu enriched layer is responsible.

However, Brinson et al [7] present some
results showing clearly the occurrence of several deformation mechanisms other than elastic
distortion of the crystalline structure during each of these three stages.
The classical additive decomposition of the strain rate is assumed : ε& 0 with E el in el σ εεε ε =+ = & && & & , (4) where and are the elastic and inelastic strain rates, respectively.
Taking into account the equations (4), the additive decomposition of the strain rate is thus expressed as : 0tr tr trEH el tr de de qσ ε εεε εε =++= + + Δ && && & & & (6) From these measurements and the equation (6), the absolute values of the elastic , reverse transformation and detwinning strain rates are plotted in Fig.8.b as functions of the strain ε elε& trε& deε& l0 between times (h) and (j).

W and Re segregated to the dendrite cores while Al, Ta and Nb were enriched in interdendritic regions during solidification.
In comparison to the bulk alloy composition, the dendrite cores were significantly enriched by W and Re and depleted in Ta, Al, and Nb.
Conversely, the interdendritic regions of the as-cast alloy were enriched by Al, Ta and Nb, whereas lower levels of W and Re were observed.
The eutectic γ/γ′ regions were further enriched by Ta, Al, and Nb and depleted in W and Re.

Steel is known to be easily corroded by liquid aluminum because of the dissolution of Fe in the molten Al and the diffusion of Al towards the steel bulk.
Having a limited solubility in Al and elastic properties only weakly dependent on temperature, it dissolves less in molten Al [6, 20].
One tip was also cut to identify the penetration of the Al in the steel bulk.
