“…17 TiN was preferred as the reinforcement material in the aluminium alloy matrix and to avoid cluster behaviour in the melt, an optimum concentration of 10 wt% was selected. 18 Figure 1 displays the scanning electron microscope (SEM) image of as-received TiN reinforcement particles having an average particle size of 20 ± 10 µm. The matrix and reinforcing materials were supplied by M/s Coimbatore Metal Mart, India.…”

This work explores the effect of T6 heat-treatment on the microstructure, mechanical properties and dry sliding linear reciprocating wear behaviour of Al-7Si/Titanium Nitride (TiN) centrifugally cast functionally graded composite. The 10 wt% TiN particle addition and subsequent eutectic Si spheroidisation due to heat treatment revealed an improvement in microhardness, tensile strength and wear resistance of heat-treated composite when compared to as-cast composite. Reciprocating wear analysis at varying applied loads and sliding distances revealed a combination of specimen micro-ploughing and abrasive particle action at low load and sliding distances, which was in stark contrast to the combination of abrasive and adhesive wear at higher loads and sliding distances. The surface was characterised by mechanically mixed layer formation due to tribo-oxidation, adhesive and delamination wear mechanisms. This composite can be utilised to replace traditional materials employed in reciprocating pump and compressor applications.

“…Results indicate that an optimum microwave sintering time of 2 min was essential and responsible for the improved densification and mechanical properties. The presence of TiN particles at grain boundaries plays a significant role in improving the densification and hardness values [18]. In the same year, Mondal et al investigated the feasibility of consolidating tungsten powders through microwave sintering.…”

Aluminum metal matrix composites (Al-MMCs) is a one of the most demanding engineering material due to the combination of their light weight, excellent mechanical and tribological properties. To enhance the promising advantages of Al-MMCs, microwave sintering (MWS) is an ideal and emerging technique. The unique advantages of MWS of MMCs are ascribed to the size and distribution of the reinforcement, as well as to the grain size of the matrix along with uniform and efficient heating. The objective of this comprehensive review was to highlight the viability of sintering Al-MMC in a microwave oven, and compare the material characteristics of those with similar materials sintered in a conventional furnace.

“…Hence the PM products normally have superior properties over that of their cast counterparts. It was also reported that aluminum matrix composites processed via powder metallurgy technique exhibit good isotropic properties and green density greater than 90 % of theoretical density by using low compacting pressures between 200 to 250 MPa [14].…”

In the development of Metal Matrix Composite (MMC), Titanium Carbide (TiC) of 5, 10 and 15 weight percentage has been reinforced in to pure aluminum (Al) using Powder Metallurgy (PM) technique. Aluminum and TiC were mixed in a horizontal ball mill to obtain a uniform mixture followed by pressing in a cylindrical die. Specimens so prepared were subjected to sintering at a two different temperatures of 4000C and 4500C in a tube furnace under nitrogen atmosphere for 4 hours. In this work, an attempt is made to study the influence of TiC in aluminum on physical properties like density, porosity and mechanical properties such as Hardness, Compression strength and Roughness of the surface.
