Based on tensile tests, the ultimate tensile strength (UTS) and elongation (El) of specimens under different austenitization conditions are obtained.
The specimen austenitized at 850 °C for 3 min has a UTS of 558MPa and an El of 27.99%.
In contrast, the UTS and El of the specimen austenitized at 1000 °C for 10 min are respectively 1540MPa and 5.46%, which indicates that the austenitic transformation is relatively sufficient to obtain a martensitic structure.

Klocke et al. [4] have shown that the ausferrite microstructure has a tendency to adhere with tungsten-based carbide tools.
EDS spectra of the fracture part revealed the presence of oxidized coating material (Al, Ti with high content of O).

Table 1: Chemical Composition of ADC12 (Al-Si-Cu) Alloy.
As reported by by Hongkun, et al. [10, 11] while studied the compound and microstructure of La Cu-containing hypereutectic Al–Si alloy and (A390) while La compound can indicated during Al-Si phase and Al-Cu phase such as Al-Si-La and Al-Si-Cu-La.
El Sebaie, et al. [12].
The hardness has increased with high amount of La and Ce which is in agreement with Ravi, et al. [15] and El Sebaie, et al.[12].
