Investigation of the effect of diamond nanoparticles on the structure and mechanical behavior of Mg-Ca-Zn alloy

In this paper, the study of the effect of diamond nanoparticles on the structure and mechanical properties of the Mg-Ca-Zn magnesium alloy. The influence of diamond nanoparticles concentration amount of 0.1 wt. % in the structure of alloy Mg-Ca-Zn, the ultimate tensile strength increases from 294 up to 332 MPa, the elongation value increases from 22 % up to 27 % and the yield strength increases from 66 up to 75 MPa in the tested samples. Nanoparticles in magnesium alloy do not change the hardness of the alloy. The introduction of diamond nanoparticles into the magnesium alloy increased the Zn concentration from 4 % to 4.7 % and the Ca concentration from 1 % to 1.3 %. It is found that the introduction of the nanodiamond particles into a magnesium melt contributes to a decrease in the average grain size from ~ 100 to 64 pm in the obtained castings and, as a result, to an increase in the mechanical properties.
