No full textThe objective of this study is to report the results of steady state viscoelastic properties in molten state investigated experimentally for PP/PET blends. They were prepared by the elastic extrusion method. The present paper discusses the influence of different types of PP, blending composition and effect of compatibilizer on steady state viscoelastic properties of PP/PET in molten stat

No full textThe present paper reports attempts made at enhancing the
mechanical and wear resistance properties of a commonly used aluminium alloy, the 7075 alloy by different routes. They include:
1 making composites
2 ageing of the alloy and composite
3 extruding the alloy and composite to rods.
A comparison in the properties including microstructure, hardness, mechanical and sliding wear resistant properties attained by the different routes have been attempted. It has been found that making composites drastically increases the
hardness of the alloy and extruding them further increases the value marginally. Homogenisation increases the UTS for both the alloy and composite; however, extrusion does not show any positive effect especially for the composite. The
presence of dispersoid particles changes the ductile behaviour of the alloy to a brittle failure for composites. This type of an analysis and study would help find the extent to which the properties in this alloy system can be improved and the additive enhancement if any vis-à-vis only ageing, extrusion or composite making
Sliding Wear Behaviour of Al-7075 based Metal Matrix Composite: Effect of Processing Parameters.
No full textMetal Matrix Composite made from Al-7075 based alloy dispersed with 10% SiC particles through the liquid metallurgy route were evaluated for their sliding wear properties under different loads and for a length of sliding distance. The volume loss and wear rate under different
experimental conditions were compared between the following conditions for both the alloy and composite (i) cast (ii) aged (iii) extruded. Attempts have been made to arrest wear of the alloys that experience seizure under the mildest of experimental conditions through the above processing
techniques and explain the experimental results through worn surface studies. The extent of success attained through each process has been discussed. It is felt that the cumulative effect of the different processing techniques including composite making, ageing and extrusion can open up new avenues
for this alloy system, which in general is not used for wear resistant application
