In the initial state the ultimate tensile strength (UTS) was 234 MPa, the yield strength (YS)161 MPa and the elongation (El) 9%.
These values compare favorably with those for the initial state (UTS = 234 MPa, YS = 161 MPa, and El = 9%). 3.

Introduction
Electroless (EL) deposition is commonly employed to deposit metals and their alloys without the
use of electric current, via reduction of the metal by a reducing agent.
Both EL Ni-P and composite Ni-P -ZrO2 coatings exhibit good adherence to the steel substrate and were deposited to a thickness of approximately 30 µm.
In general, EL Ni-P coating structure and properties mainly depend on the amount of P present in the deposit [11].
Szcygiel et al. [12] who had observed slight reduction of phosphorous content in the composite NiP-ZrO2 coatings, most likely due to the differences in the bath composition and the deposition temperature.
The incorporation of ZrO2 particles seems to have some influence on the EL Ni-P coating structure i.e.

Up to now, Ti is mainly added into Al melt by melting Al-Ti or Al-Ti-B (Ti/B=5:1)
master alloy.
Materials and Experimental Procedure The in-situ Ti alloying of Al alloys was carried out in an 85KA prebaked cell for Al-reduction by adding some titania into electrolyte.
Two kinds of the A356 alloys with different Ti content were produced by remelting in-situ Ti alloying low-Ti Al alloys (named testing A356 alloys) and by remelting pure Al and Al-5Ti master alloys (named transition A356 alloys) respectively.
The ductility and quality index Q (Q=σb+150×log(EL.)
The restricting factors that affect the prime α-Al grain growth also have an effect on the growth of eutectic α-Al.
