What does this research mean for the field?

In Ti3SiC2-derived network-structured TiC-Ti5Si3/TA1 composites, optimal tensile strength and ductility are achieved by using 80-100 mesh TA1 powder and controlled milling to form a continuous TiC-rich network, with Si solid-solution and grain-refinement acting as the dominant strengthening mechanisms. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

To investigate the influence of starting powder size, ball-milling speed, and milling time on the microstructure, network architecture, and mechanical properties of in situ synthesized TiC-Ti5Si3/TA1 composites.

Overview

Experimental study reveals enhanced tensile strength and ductility in network-structured titanium composites, indicating the critical role of processing parameters in microstructural design.

Key Points

To investigate the influence of starting powder size, ball-milling speed, and milling time on the microstructure, network architecture, and mechanical properties of in situ synthesized TiC-Ti5Si3/TA1 composites.
Fabricated TiC-Ti5Si3/TA1 composites via powder metallurgy and spark plasma sintering using Ti3SiC2 as an in situ reactive precursor.
Systematically varied TA1 powder particle size (including 80–100 mesh) alongside ball-milling speed (up to 300 rpm) and ball-milling duration (up to 5 h) to regulate precursor embedding and network continuity.
The specimen milled at 300 rpm for 5 h attained a maximum tensile strength of 778.72 MPa, whereas milling at 200 rpm yielded a tensile strength of 722.99 MPa alongside an apparent fracture strain of 24.74%.
Semi-quantitative analysis established that silicon solid-solution strengthening and grain refinement predominated the strength increment at 42.64% and 37.54%, respectively, supplemented by TiC-network load transfer (14.71%) and Ti5Si3 dispersion strengthening (5.11%).
Coarser 80–100 mesh TA1 powders facilitated continuous TiC-rich boundary networks, whereas excessive ball milling disrupted powder templates, introduced defects, and degraded tensile ductility.
