Kudish et al [5].
Once the spectral reflectivity rl of the body was measured, we deduce the absorptivity from al=1-rl.
On the assumption of a diffuse emission, the application of Kirchhoff's law gives el=al.

.: +49 2461/61-3694 Keywords: AA 2024, AA 7075, Al-cladding, riblet structure, fracture mechanics Abstract.
A detailed assessment of influencing factors on the riblet structuring process of AA 2024 is provided in the study by Pöplau et al. [19].
The crack initiation at intermetallic phases at the surface agrees with the findings of Mayer et al. [13].
For AA 7075, Mayer et al. [14] found a threshold value of around 1.55 MPam.
For crack lengths shorter than the El Haddad parameter a0 [26], the crack propagation regime is limited by the fatigue strength of the substrate material (cf. corrected data in Fig. 1 for AA 2024).

Al to the lower Si steel resulted in a small further increase in LME sensitivity; further work is underway to better characterize the LME behavior of Al-added steels.
Both the Low-Si and Low-Si, Hi-Al steels exhibited no ductility loss at 600°C.

Tool Wear Performance of CVD-Insert during Machining of Ti-6%Al-4%V ELI at High Cutting Speed Gusri Akhyar Ibrahima , Che Hassan Che Haronb and Jaharah Abd.
It is clearly seen that a typical three-stages pattern of tool wear was obtained, while was similar with the pattern reported by Jawaid et al. [8] when machining titanium alloy with coated and uncoated carbide tools.
Che Haron et al. [6] reports that there was a strong bonding between the chip and tool material.
As stated by Gusri et al. [13] that the depth cut significantly contributed to the cutting time when machining titanium alloy at high cutting speed.
