*2.3. Tensile Test*

Tensile test of the Mg-9Li alloys were conducted using the uniaxial tensile test at room temperature via a UTM4204X electronic tensile machine (Suns, Shenzhen, China) with a strain rate of <sup>1</sup> <sup>×</sup> <sup>10</sup>−<sup>3</sup> <sup>s</sup><sup>−</sup>1. A dog bone shape of dimensions 6 <sup>×</sup> 2 <sup>×</sup> 2 mm3 was used with at least five samples tested for each process sample and the average value obtained. The mechanical properties were measured and the fracture morphologies of the different processed alloys were observed using a scanning electron microscope (FEI Quanta 3D FEG, Hillsboro, OR, USA).
