Ultrafine-grained b-Ti 70 Nb 30 -matrix composites (TMCs) reinforced by in situ TiC ceramic particles are fabricated by spark plasma sintering of mechanically alloyed blended powders of respective b-Ti 70 Nb 30 and C powders. The results show that the fabricated TMCs with 2.5 vol% (TMC 2.5) and 7.5 vol% (TMC 7.5) in situ TiC particles exhibit almost invariable fracture strength of approximately 2 200 MPa and plastic strain of approximately 46%. To explain these results, the self-organized critical state in dynamics and the power-law distribution are used to investigate the serrated flow behavior of the stress-strain curves for the fabricated TMCs. The larger stress-drop magnitudes, fitted scaling exponents (b), and cut-off stress-drop magnitude (s c ) for the TMC 2.5 are attributed to the larger intershear band (SB) spacing and lower density of SBs. Their interactions resulted from the presence of the in situ TiC particles with lower content. In addition, the larger stress-drop magnitudes before a strain of 20% for the TMC 2.5 are due to the greater moving distance of the SBs, whereas the almost constant stress-drop magnitude after 20% strain for the two TMCs is because of SB interactions induced by the in situ TiC particles. The results obtain provide some insights into fabricating high-performance TMCs by tailoring SBs and their interactions. Fig. 10. Generated SBs and their interactions on the sample surfaces for the TNC 2.5 (a) and (c) and TNC 7.5 (b) and (d) TMCs after plastic strains of 15% (a) and (b) and 30% (c) and (d), respectively.

Wire-Arc Additive Manufactured (WAAM) is relatively new method of metal 3D printing in which the raw material is heated by the gas metal arc and the molten metal pool is deposited layer-by-layer using a computer numerically controlled axis drive system. Since WAAM needs a finishing process for attaining the final dimensions of the components, there is a need to investigate the machinability aspects of WAAM fabricated materials. This work investigates the machinability of Al-Mg 5356 alloy test samples fabricated by WAAM process using wire-electric discharge machining (Wire-EDM). The test samples were subjected to Wire-EDM and the obtained material removal rate (MRR), kerf width (KW) and surface roughness (Ra) were investigated at different Wire-EDM process settings of voltage, current, pulse-on time (Ton), pulse-off time (Toff) and wire speed (Ws). Statistical analysis revealed that current had a significant influence on MRR. Ton had a strong influence on KW and Ra, whereas Toff exhibited a considerable impact on all these responses. Notably, Ws demonstrated a significant impact on Ra. However, voltage was found to have statistically negligible impact on all the machining responses. Microstructural investigations and compositional analysis were conducted providing valuable information on the cut surfaces. The results derived from the present investigation are useful for predicting the optimum process parameter settings for machining of WAAM-based 3D printed Al-Mg alloy in various manufacturing industries.
