SiC and Al particles were added to Sn-0.7Cu powder during the mixing process.
Processing The development of Sn-0.7Cu-Al-SiC was carried out using powder metallurgy technique (PM).
Al that has a good toughness also becomes the factor of the hardness increased.

The results showed that Sb-treated Al-11%Si alloys have poor surface roughness in comparison to untreated Al-11%Si alloy.
Studies on the turning of Al-Si alloy have been performed by various researchers.
Another material investigated is the 0.5 wt.% Sb treated Al-11%Si alloy.
Figure 1(a), (b) and (c) show that Sb-treated Al-11%Si alloys have poor surface roughness when compared to untreated Al-11%Si alloy at all conditions.

As far as aluminum T-stub connections is concerned, De Matteis et al. [8] investigated for the first time the possibility of extending the provisions given by Eurocode 3 for T-stub also to aluminum joints.
Indeed, another numerical study, carried out more recently by De Matteis et al. [13], put into evidence some shortages related to the above formulations.
Experimental and numerical studies on a welded specimens made of the EN AW 6082-T6 alloy were carried out and the elastic strength Fcwt,el, expressed in Eq. 4 as a function of the effective length beff,el given in Eq. 5, was provided.
The above equation results by the assumption of a linear distribution of the tensile stresses, through the column web, characterized by a 1.7:1 slope that is lower than the one generally assumed for steel (2.5:1), according to the formulation provided by Eurocode 3, which derives from the studies carried out by Aribert et al. in 1981 [7].

Tran et al., for an example, found that brookite possessed high photocatalytic capacities for the degradation of different hazardous compounds under sunlight equivalent conditions [2].
Yu et al. [5] studied the effect of acidic and basic hydrolysis on the microstructures of titania.
However, Zheng et al [6] synthesized brookite nanocrystallites using Ti(SO4)2 or TiCl4 as the precursor with hydrothermal treatment method by controlling pH values and the reaction temperature.

The electrolytic alloys (E10 and E14) were directly fabricated by in-situ titanium alloying Al-0.18%Ti alloys which were produced by electrolytic method, while the melting alloys (M10 and M14) were prepared by the traditional route which melted the Al-10%Ti master alloys and pure Al.

Secondly, titanium reacted with aluminum and graphite, producing Ti-Al,C-Al,Ti-C compounds.
Al:Ti in all regions is close to 3:1, while Al content is slightly higher.
The Al-Ti compounds, C-Al compounds and Ti-C compounds form the matrix of Al-Ti-C mother alloy with refining effect. 2.
Alloy phases include α(Al), Al-Ti compounds, C-Al compounds, Ti-C compounds, etc.
