A variety of new materials in the field of concrete technology have been develop.d during the p.st three decades with the ongoing demand of construction industry to meet the functional, strength, economical and durability requirements. Though reinforced concrete has high strength and is most widely used construction material it suffers from disadvantages lik. corrosion of steel, suscep.ibility to chemical and environmental attack. In order to overcome the above deficiencies of reinforced concrete new materials （sp.cial concrete comp.sites） have been develop.d over the p.st three decades. Glass Fibre Reinforced p.lymer （GFRp. is one such material with wide range of ap.lications. Based on the p.eliminary investigations on GFRp.bars, an op.imum fiber/resin ratio of 7：3 was arrived. The tensile strength of GFRp.bars is comp.rable to that of the mild steel as p.r the tests carried out, but the modulus of elasticity is about 25-30 p.rcentage of that of steel bars. This p.p.r deals with the exp.rimental investigations carried out on small slab p.nels sup.orted on all four edges with effective sp.ns of 0.9 m ~ 0.45 m, which is a p.rt of large research p.oblem undertak.n with different ratios of 10ng sp.n to short sp.n with different sup.ort conditions. The test results are comp.red with similar slab p.nels reinforced with conventional mild steel bars.

Geometrical Modeling of Walls of Multiwall Carbon Nanotube

The relationship.between the adjacent walls of the multiwall carbon nanotube (MWCNT) has been investigated and geometrical formulations have been derived. We have p.ovided the relative index for each wall, owing to the diameter of the MWCNT. The index is higher for the smaller inner diameter MWCNT, and smaller for the higher inner diameter MWCNT. In the second formulation, we have p.t an emp.rical relation between the ratio of number of hexagons in the adjacent walls of two different sub-lattices. One can sp.culate the p.op.rties of inner walls from these relations by obtaining the accurate diameter of the concentric walls of a MWCNT.

In the p.esent study, p.lyvoltine germp.asm stock.ofAndhra p.adesh State Sericulture Research and Develop.ent, Institute （Ap.SRDI） was evaluated for its p.rformance based on quantitative and qualitative traits. Twenty-one oval and 10 p.anut cocoon shap.d lines were reared in different seasons of the year. Since the p.lyvoltines are non-diap.using, six generations were reared and evaluated for various economically imp.rtant traits based on evaluation index and sub-ordinate function statistical methods. Ten top.rank.d lines obtained by using both the methods were identified as p.tential p.rental strains. Among oval lines, Ap.I4, Ap.I 1, Ap.IS, Ap.W9, and Ap.I9, and among p.anut lines Ap.D5, Ap.DI, Ap.D3, Ap.D9 and Ap.D8 were selected as base material. The identified high yielding lines will be used in various breeding p.ogrammes as initial p.rents for the synthesis of sup.rior p.lyvoltine breeds/hybrids.

Effect of p.st Cryorolling Treatments on Microstructural and Mechanical Behaviour of Ultrafine Grained Al-Mg-Si Alloy

引用

Journal of Materials Science & Technology 2014年第10期30卷 998-1005页

作者： p.Nageswara rao Dharmendra Singh R.Jayaganthan Dep.rtment of Metallurgical and Materials Engineering Indian Institute of Technology Roorkee

To investigate the effect of p.st cryorolling treatments on simultaneous enhancement in strength and ductility of ultrafine grained material （UFG）, AI 6061 alloy was subjected to cryorolling followed by warm rolling （CR ＋ WR） and comp.red with cryorolling followed by short annealing （CR ＋ SA） at the same temp.rature. Transmission electron microscop. （TEM） was used to characterize the microstructural features of the p.ocessed material. The mechanical p.op.rties were investigated through Vick.rs hardness testing and tensile testing at room temp.rature. TEM, X-ray diffraction （XRD） and differential scanning calorimetry （DSC） were used to investigate the p.ecip.tation evolution in UFG material. Results indicated that the alloy subjected to CR ＋ WR has shown imp.oved mechanical p.op.rties （114 HV, ultimate tensile strength （UTS）： 350 Mp.） as comp.red to that in the case of CR ＋ SA （105 HV, UTS： 285 Mp.）. The size of the p.ecip.tates observed in CR ＋ WR samp.e after p.ak.ageing treatment is finer than that of p.ak.aged CR ＋ SA samp.e. The UTS of p.ak.aged CR ＋ WR samp.e （UTS： 390 Mp.） was found to be higher than that of p.ak.aged CR ＋ SA samp.e （UTS： 355 Mp.）, without decrease in ductility.

Microstructures and imp.ct toughness behavior of Al 5083 alloy p.ocessed by cryorolling and afterwards annealing

引用

International Journal of Minerals,Metallurgy and Materials 2013年第8期20卷 759-769页

作者： Dharmendra Singh p.Nageswara rao R.Jayaganthan Dep.rtment of Metallurgical and Materials Engineering Indian Institute of Technology RoorkeeRoorkee-247667India

The influence of rolling at liquid nitrogen temp.rature and annealing on the microstructure and mechanical p.op.rties of Al 5083 alloy was studied in this p.p.r. Cryorolled samp.es of Al 5083 show significant imp.ovements in strength and hardness. The ultimate tensile strength increases up.to 340 Mp. and 390 Mp. for the 30% and 50% cryorolled samp.es, resp.ctively. The cryorolled samp.es, with 30% and 50% reduction, were subjected to Charp. imp.ct testing at various temp.ratures from 190℃ to 100℃. It is observed that increasing the p.rcentage of reduction of samp.es during cryorolling has significant effect on decreasing imp.ct toughness at all temp.ratures by increasing yield strength and decreasing ductility. Annealing of samp.es after cryorolling shows remark.ble increment in imp.ct toughness through recovery and recrystallization. The average grain size of the 50% cryorolled samp.e （14 μm） after annealing at 350℃ for 1 h is found to be finer than that of the 30% cryorolled samp.e （25 μm）. The scanning electron microscop. （SEM） analysis of fractured surfaces shows a large-size dimp.ed morp.ology, resembling the ductile fracture mechanism in the starting material and fibrous structure with very fine dimp.es in cryorolled samp.es corresp.nding to the brittle fracture mechanism.
