Abbott et al.[4] have reported that for magnesium die cast alloys AS21 AM60 and AZ91, the strain rate sensitivity decreases with increasing Al content for a strain rate range 0.012s-1~1.2 s-1.
Aune et al.[5] studied the behavior of three different die cast magnesium alloys (AM50A, AM60B and AZ91) at strain rates from 15s-1 to 130s-1, and discussed the sensitivity of flow strength to the strain rate.
In addition, AZ80[6],AZ91[7],Zk60[8],WE43[9],et al. were studied in wide strain rates range from 10-3s-1 to 103s-1.

Elementary analyzer(Vario EL cube) is used to determine the content of non-metallic elements such as C, H, S and N, while X fluorescence analyzer(XRF - 1800) is used to determine the metallic element in the sample.
The data is near to reports by Roy C et al[15] and Chaala A. et al[16].
Fe and Al are two major metals in the sample because steel and aluminium alloy are usually used for automotive industry [17].

In this study, the behavior of nitriding in ultra low carbon steels containing Cr and/or Al and/or V are investigated.
However, the steel containing additional Al (1Cr-1Al-0.3V steel) had an extremely high hardness of 1000Hv and the base steel had the lowest hardness value of 400Hv.

Li, Hu and He el al. made research on the origin and offshore extent and temporal changes of floating algae bloom in coastal waters off Qingdao using NASA’s Moderate Resolution Imaging Spectroradiometer (MODIS) data[1-3]; Using floating algae index and multi-resolution remote sensing data from MODIS and Landsat, Hu et al. found that U.
Prolifera patches in Yellow Sea(YS) and East China Sea are all originated from the nearshore Subei Bank[4]; Yi et al. analyzed the concentrations of Enteromorpha coverage and their drift paths from environmental hydro meteorological conditions in 2009 compared with it in 2008, and considered that the wind is the strongest factor of the Enteromorpha drifting[5]; Qiao et al. simulated microalgae drift characteristics in the YS during June and July in 2008 and 2010 using a three-dimensional wave-tide-circulation coupled model[6].

Ratnam et al. [7] reported earlier that irradiation-induced reactions occur both in double bond and epoxy regions of ENR.
According to Datta et al. [10] and Banik and Bhowmick [11], oxidative crosslinking and chain scission are believed to be prevailing reactions.
According to Ang et al. [15], the irradiation-induced crosslinking in polymers is often reflected by the hardness of the irradiated sample.
This is similar to irradiated ENR50 which have been studied by Ratnam et al. [7] who observed that the hardness of ENR50 was increased with irradiation.

On the contrary, Chen [6] and Sardinas et al. [11] saw significant effect on delamination when cutting speed was increased.
Rawat et al. [14] focused on the wear mechanisms and tool life of standard two flute tungsten carbide (WC) drills when drilling CFRP at high speed.
Similar study done by Iliescu et al. [16] noted that coated drills performed better than uncoated drills in term of tool life by suppressing tool wear.
Durao et al. [12], Enemuoh et al. [17], Davim et al. [24], and Tsao et al. [27] reported that low feed rates reduces thrust force and thus reduces the possibility of onset delamination.
