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

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 cryo-

treatment 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 metal’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

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 high-strength 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.

anisotropy, delamination, banded microstructure, TMCP
