Critical Review of Fatigue Properties of Friction Stir Welds of Aluminum Alloys Kondapalli Siva Prasad1*, Chalamalasetti Srinivasa Rao2, Damera Nageswara Rao3 1

Abstract Friction Stir Welding (FSW) is a solid state welding technique being developed for various metals and alloys. It allows joining of high strength aluminum alloys which is generally difficult to weld with conventional welding techniques. This joining technique is energy efficient, environment friendly, and versatile. FSW is considered to be the most significant development in metal joining in a decade. It is expected to have various weld properties to meet the requirements of applications and working conditions of the products. These properties include tensile strength, microhardness, residual stresses, bending stress and fatigue life. Fatigue is one of the main causes of failure of welded structures in various applications where repetitive cyclic/repeated application of force or pressure conditions is prevailed. There is still lack of material property data, especially for fatigue, for this relatively new method of joining technique. In this paper fatigue properties of Friction Stir Welds of various Aluminum alloys and composites of different research papers are critically analyzed for testing process and results. This state of the art technology has very high potential in many applications including defense, automobile, aerospace, high pressure vessels, pipe joining and ship building.

Keywords: Friction stir welding, fatigue life, aluminium alloy

Feasibility of Cryogenic Treatment for Improving Lattice Strain Distribution in AA7010 Alloy C. L. Gogte1, Ajay Likhite2*, D.R. Peshwe2 1

M.I.T. College, Aurangabad, India 2 V.N.I.T., Nagpur, India

Abstract In the present investigation, AA7010 was subjected to two different cycles of cryogenic treatment. In one cycle, the cryogenic treatment was given after the quenching and aging, whereas in another cycle the treatment was given immediately after quenching before aging. The hardness and XRD results of these samples were compared with that of T6 conditioned sample, taken as the reference. The samples, which were given cryotreatment immediately after quenching before aging, were found to have higher hardness than T6 condition samples. It was also observed that the internal strains in these samples, although more than the T6 conditioned samples, is more uniform than the later.

Keywords: cryogenic treatment, 7XXX alloys, age hardening

Abstract There is impending shortage of metallurgical engineering fresh graduates, partly due to their exodus into more remunerative and rosy sectors. This paper attempts to highlight the problems and also offers conceptual solutions to abate them. One of the most potent solutions lies in the requisite motivation of students to get thickly absorbed in the TQM (total quality management) environment. This paper attempts to pose issues and map the framework for initiating corrective and preventive actions. In its vital failing the consequent shortage of metallurgical engineering graduates is all set to jeopardize the governmental plans for chasing metal production (as per planned requirements) in India. It is envisaged that the solution rests in improvement of capatence (capacity + competence) and compettitude (competence + attitude) of both teacher and student, beginning right from the teacher. Continual Improvement in quality of teachers by improving pedagogical skills and attitude should be expeditiously harnessed in line with the voice of the customer.

Keywords: Metallurgical engineering education system (EES), capatence, compettitude, voice of customer (student)

Interference of Components in Metallic Diffusion Honey Garg, Priyavrat Thareja* Department of Materials and Metallurgical Engineering, PEC University of Technology, Chandigarh-160012, India Abstract Eight different pairs of metals which diffuse in each other in a solid state composition and make a homogenous or heterogeneous mixture are considered for deeper understanding of diffusion phenomenon, w.r.t. direction of diffusion, etc. Further the authors interpret which factors are responsible for the metal and/or more specifically which metal atom will be active in the diffusion process. The analysis evidenced number of breakage of bonds in the substrate of the metals participating in the diffusion process and metalâ&#x20AC;&#x2122;s thermal conductivity additionally mattered. Study of greater influence, to make a clear judgment of active metal in the diffusion process, solicited decision as to which metal is active in the binary solid-solution diffusion process? The study reveals that there is a very close relationship between the active metal and the physical traits. The dependence of thermal conductivity, number of breakage of bond is analyzed using tabulation of the diffusion direction and the physical properties while defining the diffusion direction for typical pair of the metals.

Keywords: Diffusion direction, number of breakage of bond, solid state alloy development

Understanding the Delamination and Its Effect on Charpy Impact Energy in Thick Wall Linepipe Steel Tushal Kyada, J Raghu Shant*, Rajesh K Goyal, T S Kathayat Welspun Corp Ltd., Gujarat, India

Abstract The thick wall linepipes produced from thermo-mechanical-controlled hot-rolled highstrength low-alloy steel (HSLA) plates are characterized by heterogeneity of microstructures through thickness. This microstructural heterogeneity results delamination and is responsible for substantial differences in the toughness behavior of the linepipe steel. The objective of this research work was to investigate these differences in impact energy using Charpy V-notch impact test in correlation with microscopic observations on fractured surfaces of the selected Charpy V-notch specimens. A thick plate of linepipe steel having grade API 5L X65MS PSL2 (API: American Petroleum Institute) was selected for present study.
