“…Materials obtained by SPS feature high density (close to the theoretical one) and mechanical properties [18]. As one can see from Table 1, which summarizes the work results [19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38], the Ti alloys obtained by SPS have high hardness and strength as well as good plasticity (for certain sintering conditions). In some cases, the Ti alloys obtained by SPS have high corrosion resistance [33][34][35].…”

The research results of the microstructure and corrosion resistance of Ti and Ti-Al-V Russian industrial titanium alloys obtained by spark plasma sintering (SPS) are described. Investigations of the microstructure, phase composition, hardness, tensile strength, electrochemical corrosion resistance and hot salt corrosion of Ti-Al-V titanium alloy specimens were carried out. It was shown that the alloy specimens have a uniform highly dense microstructure and high hardness values. The studied alloys also have high resistance to electrochemical corrosion during tests in acidic aqueous solution causing the intergranular corrosion as well as high resistance to the hot salt corrosion. The assumption that the high hardness of the alloys as well as the differences in the corrosion resistance of the central and lateral parts of the specimens are due to the diffusion of carbon from the graphite mold into the specimen surface was suggested.

The present research of the article is used to describe the microwave sintering of nitinol composite and its surface topography analysis by atomic microscopy (AFM). Scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS) technique is used to analyze the characterization and alloying composition of the composite. Silicon carbide is the reinforcing particle between nickel and titanium. Wear test is conducted to investigate the worn surface morphology of the sintered specimen. The synthesized composite has exceptional material properties such as ultimate tensile strength of 1020MPa, 16% of elongation to fracture, 7.51 g/cc of density and hardness of 310 HV. Low wear rate of 0.01 mg/m is perceived at minimum load and minimum sintering time. Surface roughness is varied from 22.87 to 54.05nm at different sintering time. Maximum roughness height of 327.6 nm is observed in the surface profile of the composite.

“…In powder metallurgy technique, sintering is a process which involves heating of metal powder in a protective environment below its melting point. It is carried out at elevated temperature between 65-85% of the powder's melting point [12]. Novel sintering methods such as hot pressing, hot isostatic pressing, microwave sintering and spark plasma sintering have been reported in literature for fabricating materials [13].…”

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.
