Plasticity and Metastability of AISI 204 Cu Austenitic Stainless Steel Sheets in Tension
A utensil grade metastable austenitic stainless steel, AISI 204 Cu was tested for plastic flow, tensile properties and strain-induced phase change, and martensite formed. Results were compared with AISI 304, a typical stainless steel usually used in similar applications. AISI 204 Cu showed higher strength properties and little lower ductility properties. Two different martensite phases, å-martensite (hexagonal close-packed, h.c.p.) and á’-martensite (body-centered cubic, b.c.c) have been observed. X-ray and TEM proved the phase change.

Experimental Investigation of Heat Transfer in Double Pipe Heat Exchanger Using Cerium Oxide Nano fluid
Heat exchanger is a very important device in every modern industry. In this research work, the thermal performance analysis of a pipe in pipe heat exchanger is performed by varying the composition of nanofluid used, which is a mixture of Cerium Oxide (CeO2) and water. An experimental analysis will be performed on pipe in pipe heat exchanger by varying volume concentration (2%, 3%, 4%) of nanoparticles in nanofluid at different flow rates (7, 8, 9 litres/min) of nanofluid flow. Experimental results such as heat transfer rates, overall heat transfer coefficient, Reynolds number, Nusselt number and heat exchanger effectiveness will be calculated to analyse the performance of heat exchanger. The objective of this research work is to check the use of Nano fluids to improve the heat exchanger’s performances and at what percentage of Nanoparticle-coolant mixture, the performance of pipe in pipe heat exchanger will obtain maximum heat exchange rate.

Mechanical Properties and Triobological Behavior of Stir Cast Al-6063 Alloy Based Hybrid Composite
India is one of the developing countries that need to face the many challenges in automotive industry. In industries usage of heavier materials are replaced by aluminium alloys because of its good properties. The objective of this work is investigating the influence of quarry gravel powder (QGP), silicon carbide (Sic) and fly ash (FA) particles of fraction percentage on the mechanical properties and wear behavior of Al6063 based alloy metal matrix composites. The abrasive ceramic particles, fly ash and gravel powder reinforced in the metal matrix are the cause of improvement in mechanical and tribological properties of the materials. The al 6063 metal matrix hybrid composite consist of 4 wt%, 6 wt%, and 8 wt% QGP-SiC–FA respectively was processed by using stir casting technique procedure. Tribological Wear behavior of the developed hybrid composites was characterized at different loads, sliding velocities and distances using pin-on-disc method. The experimental results are discuss that the applied load and reinforcement of wt% are the major parameters influencing the specific wear rate for all samples, followed by weight fraction of reinforcement, sliding velocity and sliding distance.
Analysis of Epoxy Resin with Natural Materials
In the research, we have discussed about the effect of epoxy resin with natural materials. Thereby, here we decided to develop the composite materials using natural materials like chicken feather, coconut sheath, banana pseudo stem, teakwood dust. Here the review based information is piled up to get the wide-ranging information about the mechanical properties of natural materials based composites. The natural composites have more advantage like light weight, wide availability, low price, renewability and mechanical properties. Composite specimens are prepared referring to ASTM standard by pouring the mixture of epoxy resin matrix with natural materials of particular size. Specimens so developed are tested in laboratory for various tests. The properties are thus noted and they are briefly noted in the report.
