Title | : | Analysis of Hardness of Nano-Composite (TiSiBC) Coated SS 304 sheet |
Country | : | India |
Authors | : | Sandeep Yadav || Dr. Suman Kumari Mishra |
Abstract: The coating of the Nano-composites on sheet metal enhances its mechanical properties for a product and increases its mean life and the performance. In the present study, TiSiBC Nano-composites coating on SS-304 sheet is deposited by magnetron sputtering. It is evaluated that the, SS-304 sheet deposited with layers of varying thickness, has different mechanical properties. It is further evaluated that as the thickness of the deposited layer increases, the hardness of the sheet metal increases and wear of the material decreases.

Authors | : | Amit || Prof. M F Wani |
Abstract: In this paper tribological properties of virgin, 25% glass fibre reinforced (GFR), PTFE polymers were studied under dry sliding conditions. PTFE samples were prepared by compaction moulding. Friction and wear experiments were run under ambient conditions in a pin-on-disc arrangement. Effects of sliding distance and load on friction and wear were investigated. Test was carried out at sliding distance of 500-, 1000-, 1500- and 2000m, under load of 5-, 10-, 20-, and 30N...........

Title | : | Processing and Characterization of Al-Flyash Composite by Stir Casting |
Country | : | India |
Authors | : | Kiran || G B Rudrakshi || S M JIgajinni |
Abstract: In this paper the study on wear behavior, tensile and microstructure characterization of composite material made up of base metal Aluminium 6061 and reinforcement material fly ash processed by stir casting technique. Three combination of composite were produced by adding 3,6,9 percentage weight fraction of fly ash with base metal Aluminium 6061. The microstructure of all the specimen were observed in optical microscope and distribution of reinforcement material is observed. From the results wear tests the variation of wear rate is directly proportional to the load, as the load increases wear rate increases and tensile test has given the result that UTS of the as cast is less than the composite material.

Authors | : | K. Kiran Kumar Rao || Dr. Sharanappa.G || Dr. A. Ramesh || Dr. G. Naga Malleswara Rao |
Abstract: Refrigeration is plays vital role in human life and it has become prominent to human habitat, primarily for the preservation of food grains, medicine also for large quantity storing of Chemicals, Industrial cooling, and air conditioning. In Conventional refrigeration systems Freon is used as refrigerant. As they are the main cause of pollution, depleting of ozone layer, cause health hazard. To avoid this damage extensive research work is going on alternate refrigeration systems. Vortex tube (VT) is non-conventional cooling equipment, without moving parts which are capable of separating hot air stream and cold air stream form an inlet air stream with desired pressure without affecting the environment. This device suits for vital applications due to its light weight, simple and more importantly it is compact.

Title | : | Experimental Investigation Of Mechanical Properties Of Friction Stir Spot Welding Using Circular Profile En 31 Tool On T6061 And T6082 Aluminum Alloys |
Country | : | India |
Authors | : | B.Srinivasulu || Dr.Namish Mehta |
Abstract: Efforts to reduce vehicle weight and improve safety performance have resulted in increased application of light-weight aluminum alloys and a recent focus on the weldability of these alloys is need of the day. Friction stir spot welding (FSSW) is a solid state welding technique (derivative of friction stir welding) which was developed as a novel method for joining aluminum alloys. During FSSW, the frictional heat generated at the tool-workpiece interface softens the surrounding material, thus the rotating and moving pin causes material to flow. The forging pressure and mixing of the plasticized material result in the formation of a solid bond region. In the present work, Aluminum alloy plates 6061 and 6082 are joined by friction stir Spot welding (FSSW) using EN31 Tool material with Circular Profiles by varying welding parameters such as rotational speed, Feed and inclinational angle of the tool. It is evaluated that tensile strength is more for friction stir spot weldment joints of dissimilar metal than similar metals used in the study.

Authors | : | T.G.Arul || A.Manimaran || P.Ranjith |
Abstract: Globalisation has brought in cut throat competition in Indian Manufacturing Industries. To improve competitiveness, they started implementing operations management techniques like Lean Manufacturing, Total Quality Management (TQM), Total Productive Maintenance (TPM), etc. Single Minute Exchange of Die (SMED) is a lean manufacturing technique to setup time reduction that can be applied in any factory to any machine, originally introduced by Prof. Shigeo Shingo in Japanese industries in the 1950s and it is one of the principal elements of Toyota Production System (TPS) [8]. It was observed that the setup change takes 76 minutes in a 300T press shop, which is very high. Hence, it is decided to apply SMED concepts to reduce the setup...........

Abstract: In this paper, the consequences of an experimental study of effect of particle size of fly ash particles on mechanical properties of fly ash reinforced aluminium alloy (Al6061) composites samples, processed by stir casting route reported. Fly ash is one of the most promising inexpensive and low density reinforcement available in large quantities among other reinforcement. Even though, it is a solid waste by-product obtained from thermal power plants. Fly ash has been used as filler in aluminum, polyester, epoxy, polyurethane and various rubbers. This development is largely due to the advantages of fly ash such as low density, strong filling ability, excellent fluidity and good processibility............

Title | : | The Relationship between Differentiation Strategy and Firm Performance: a Mediating Role of Quality Management |
Country | : | India |
Authors | : | Manjeet Kharub || B. K. Patle || Gaurav Sharma |
Abstract: In order to sustain long-term performance, the importance of competitive strategy has been well recognised in many organisations. This paper examines the impact of competitive differentiation strategy on firm's performance and the mediating role of quality management (QM). Study results found no direct relationship between differentiation strategy and firm performances, but, QM entirely mediated their relationship. Empirical results concluded that (i) design and development and (ii) information and analysis are the two components of QM which are successful in mediating the relationship between differentiation competitive strategy and firm performance. Thus, for a firm pursuing differentiation competitive strategy a clear understanding and the emphasis on these two components of QM is crucial to maximising profits and hence the competitiveness.
