This process was studied upon synthesis of Ti-6Al-4V composition using 60%Al-40%V MA powder.
(a) bright areas: Al 2.0%, Fe 5.5%, dark areas: Al 19.7%, Fe 0%; (b) bright areas: Al 4.0%, Fe 2.7%, dark areas: Al up to 14.3%, Fe 0%, SEM.
Taking into account the experimental results and modeling of titanium and titanium alloys synthesis, high balance of mechanical properties of CP-Ti (UTS ≥550 MPa, El. ≥25%) and widely used titanium alloy Ti-6Al-4V (UTS ≥940 MPa, El. ≥10%) was reliably attained.

Peres et al. [15] studied numerically the convective exchanges in the same grooved gap to the stator as Bouafia et al. [14].
Bouafia et al. [16] continued their work by combining an experimental and numerical study. 
Neti   et al. [17] developed a numerical code based on finite differences. 
Levy et al. [18] compared these numerical results with experimental results.

The use of binder and fly ash to stabilize Al slag has a high UCS.
XRF Analysis of Al slag, Fly Ash and GBFS Binder Composites.
Fly ash and a binder were used to stabilize the al slag.
Al slag and binder had high percentages of Al, Si, and Ca which contributed as the backbone for enhanced microstructure and mechanical performance.
