Materials, method and Characterization The substrates used is Ti6Al4V with the following chemical composition (wt %): Al (6), V (4) and Ti (balance).
The increased in surface hardness of microwave plasma nitrided Ti6Al4V suggested due the existence of Ti2N and TiN phases in a form of compound layer where this is also observed by El hossary [10].This is in agreement with an increase of Ti2N and TiN peak intensities observed in the XRD patterns of the plasma nitrided samples (Figure 1).

The Influence of Milling Time and Impact Force on the Mutual Diffusion of Al and Cu During Synthesis of Al-4.5wt%Cu Alloy via Mechanical Alloying A.
The study of mechanical alloying (MA) process on the immiscible Al-Cu systems having positive heats of mixing has been investigated by the earlier researchers.
The aim of the present work was to study the effect of milling time and BPR on the mutual diffusion of Al and Cu during synthesis of Al-4.5wt%Cu alloy by high energy mechanical milling.
Therefore the mutual diffusion of Al and Cu will be increased with increasing the milling time and BPR during MA process.

This means that AlB12-type Al-B alloys can be prepared by high temperature treatment of the produced AlB2-type Al-B alloy melts.
Experimental AlB12-type Al-B alloys were prepared by high temperature treatment of AlB2-type Al-B alloy melts.
The intended nominal composition was Al-3 wt.% B.

The steels were generally Al-deoxidised but one V-N steel was Si-deoxidised.
In summary, in the Al-deoxidised steels, BSEI and EDS identified the major single phase inclusions to be elongated or globular MnS and angular or globular Al-rich inclusions (assumed to be Al2O3, since no other elements were detected by EDS).
The ductility (as measured by RA % and El %) of the Ti-free steels is reduced compared to the Ti-treated steel and is associated with a change from mixed transgranular/intergranular cleavage and ductile fracture (Ti-free steels) to fully transgranular ductile failure (Ti-treated steels).
