“…The succession of procedure steps in the Powder Metallurgy process includes blending powder, compacting that blended powder into a die, followed by sintering process in a consolidation chamber. Specific behavior or dimensional accuracy may be implemented in secondary service [4][5][6]. The steps involved in Powder metallurgy techniques are given as below (i) Preparation of metal alloy powder, (ii) Blending or mixing, (iii) Compacting, (iv) Sintering, (v) Sizing or impregnation, (vi) Secondary operations.…”

Powder metallurgy (PM) is a technique in which materials or components are made from metal powders. In this paper, the overview about titanium alloys and their advantages over engineering applications has been discussed. They are very strong and also possess great mechanical properties and incredible corrosion and wear resistance, and also capable of performing operations at elevated temperatures approximately up to 600ºC. This paper provides various compositions of titanium alloys and various powder metallurgy techniques used for sintering powders of various compositions and their applications. The properties of titanium compounds show the manufacturing of cost effective component. As a result of their fantastic mechanical, physical and organic execution they are finding consistently expanding application in biomedical applications.

“…5 boron carbide (B 4 C), silicon carbide (SiC), titanium carbide (TiC), aluminium nitride (AlN) and aluminium oxide (Al 2 O 3 ) have been added as reinforcement companion. [6][7][8] Among the above classification of reinforcements researchers have predicted that adding oxides in magnesium has drastically improved the properties of the composite materials. 9 Milli Suchita Kujur et al 10 developed a new high-performance Mg-0.5Z n -1.5 CeO 2 -rare earth oxide (REO)-based nanocomposites with excellent mechanical properties and corrosion resistance while effectively avoiding the potentially toxic effect of RE elements.…”

In this study, an attempt is made in producing composite materials by reinforcing cerium oxide with magnesium matrix. Very limited research has been carried out by using cerium oxide as a reinforcement through powder metallurgy technique. Hence the effects of reinforcing cerium oxide on microstructure, mechanical and wear properties in magnesium matrix are studied. The weight percentage of the reinforcement is varied by 3, 6, 9 and 12. Microstructural, mechanical properties like density, microhardness and compression strength and wear properties were studied for the fabricated composites. Scanning electron microscope with energy dispersive X-ray analysis (EDX) and X-ray diffraction (XRD) exhibited uniform distribution of cerium oxide and its presence in the matrix, respectively. Line scan mapping was also carried out on the samples to identify the particles present at that particular region in the matrix. The increase in cerium oxide has reduced the density but increased porosity in the composite materials. The microhardness and compressive strength have gradually increased with an increase of reinforcements. The microhardness has increased up to 40% and compressive strength has increased from 83 to 176 MPa for 12% cerium oxide, respectively. The wear resistance has also increased with an increase in reinforcement and a 28% increase in wear rate was inferred. SEM images of the worn surface exhibited good grain refinement of ceramic oxide in the matrix.

“…B 4 C-reinforced Ti-6Al-4 V composites also showed improved hardness, corrosion resistance, and higher densification. [8][9][10][11] Gürbüz et al 12 attained optimum density and hardness at 1100 °C and 120 min sintering of 0.15 wt% GNPs fortified Ti composites. Mu et al 13 processed 0.1 wt% GNPs reinforced Ti composites also showed 54.2% higher strength than pure Ti alloy.…”

This study used SiCp, SiCw, B4C, and GPLs as reinforcements for Ti750 matrix alloy and composites synthesized by spark plasma sintering. The oxidation performances of the composites were then evaluated at 800 °C. 5 vol.% SiCp reinforced Ti750 composite recorded the least oxidation weight gain of 3.80 mg.cm−2, about 41.8% of the base alloy. The average oxidation rates K + of the five materials at 800 °C were less than 1 g.m−2.h−1, indicating all materials were within the anti-oxidation grade with excellent anti-oxidation performance. The oxidation products of the samples contained TiO2, Al2O3, and SiO2. 5 vol.% SiCp reinforced Ti750 composite had significantly flatter and denser oxide film, which was well bonded with the matrix thus having a better protective effect than the matrix material. With the addition of SiCp, the thickness of the oxide film decreased, and the resistance of the material significantly improved its high-temperature oxidation performance.
