Hybrid Spark Plasma Sintering of Materials: A Review

Abstract

This article presents a review on hybrid spark plasma sintering technology (HSPS) of engineering materials. Hybrid sintering is a recently developed method used in fabricating materials, which provides a superior heating within and across the regime of the material. It integrates the heating system of spark plasma sintering with an additional resistance or induction heating in order to manufacture materials that require larger size or diameter. Materials obtained through this technique are highly dense due to rapid heating rate which ensues in a very short sintering cycle. Hybrid sintering eliminates thermal gradient that is noticeable in other sintering techniques. Fabricated materials from HSPS are utilized in aerospace, automobile and chemical industries and they tend to yield improved mechanical properties.

Synthesis and Evaluation of Strengthened Copper with 3 wt. % TiC and/ or Al2O3 Prepared By SPS Technique

“…In the present work, pure copper reinforced with nano TiC or Al2O3 nano particulates, and their effects on the mechanical properties are investigated. Reinforcements are dispersed in the copper matrix via low energy ball milling, and the admixed powders are consolidated by HSPS [37]. Hybrid sintering is a recently developed technique used in materials fabrication, which provides superior heating within and across the material regime.…”
