There are certain drawbacks to the relatively less expensive Cu-based SMAs (Cu-Zn-Al, Cu-Al-Ni, and Cu-Al-Mn), which stated to be second only to Ni-Ti by SM qualities [10].

In this work we developed Al diffusion and Al-Si and Al-Si-RE (RE: reactive element Y, Ce) co-diffusion coatings on a low cost austenitic 18Cr10Ni-steel.
In comparison, Pint el al. developed Chemical vapour deposited (CVD) FeAl coatings on the same austenitic steel as coated in this work [4].

Al-Si and Al-Si-RE (RE: reactive element) coatings were also developed by the pack cementation procedure.

Among weldable Al-alloys suitable to plastic working, the group of Al-Mg alloys (of 5xxx- series) of good weldability and relatively good service conditions are still the most popular [5, 6].
An alternative to these alloys could be the Al-Zn-Mg (7xxx series) alloys.
They exhibit higher strength properties than the mechanical properties of Al-Mg alloys [6, 7].
During the study, determined parameters such as ultimate tensile strength UTS, yield stress YS, and elongation EL.

The tensile properties are summarized in Table 1 namely, 0.2% yield stress (YS), ultimate tensile stress (UTS), elongation (EL) and reduction of area (RA).

Alloying with Si, Al or P is intentionally used to suppress the formation of iron carbides and the decomposition of austenite [1,3].
The average carbon contents in these cases were determined to be ≈ 0.90 and 1.04 % respectively for the High-Al and High-Si steels.
A typical example is shown in Fig. 3a and b for the High-Al steel with TQ = 225 °C.
Hardness values of the High-Si steel DQP samples were marginally higher in comparison to those of the High-Al steel samples.

Fig. 3 (a) and Fig.3 (b) shows that both in the range of Ti: Al: C=2:1:0.6~0.8 and Ti: Al: C = 2:0.87:0.57~0.8, Ti3AlC2, Ti and Al are able to synthesis dense Ti2AlC block by this process.
Adjust Al content in the preparation of starting materials.
It is suggest that, with a certain loss of Al and C, that is, Ti2AlC can maintain the structure stable with C and Al vacancy
