Some Creep-Rupture Data Analytics as Applied to AISI 310S Superalloy Austenitic Stainless Steel Sheets at Elevated Temperatures and High Applied Stresses
Abstract: Creep-rupture of AISI 301S stainless steel is analyzed at 973-1073K and 40-150MPa. Various creep curves and creep rate curves are compared to understand the effect of temperature and applied load. Creep deformation and creep fracture mechanisms are manipulated from concerned mechanism maps. Creep deformation follows high temperature climb. Creep activation energy so obtained is 345KJ/mol. It is larger than activation energy for self-diffusion in pure FCC iron (that is 270-311kJ/mol). …

A Study on the Sintering Behavior of Al2O3/Y2O3 Doped ZrO2 Composites
Abstract: AbstractZirconia ceramics are widely used as cutting tools due to their very high hardness, excellent fracture toughness, flexural strength, and wear-resistance properties. Tetragonal zirconia exhibits better mechanical properties due to the transformation toughening of zirconia. The superior mechanical properties in zirconia are mainly due to higher density and controlled microstructure. In the present work, an attempt has been made to prepare near full-dense zirconia bodies with controlled microstructure by optimizing …

An Overview of Poroperm Relationship in the Recognition of Heterogeneity in Petroleum Reservoirs
Abstract: Reservoir heterogeneity is comprehended on different scales based on vertical and lateral variations in the hydrocarbon bearing sedimentary sequences. The two depositional systems, Sand-shale and carbonate with complex patterns based on properties of rocks help in deciding quality of rocks, the most important being the porosity permeability relationship. The intricate relationship of these two parameters if discussed in connection with sampling depth gives better understanding of variations in vertical direction …

Managing Hydro Resources of Pakistan: A Proactive Approach for Disaster Response
Abstract: Our county has been bestowed with sufficient water resources, yet it is facing water shortages due to mismanagement and changing weather phenomena. Pakistan’s vulnerability to natural hazards had increased many folds because of this issue, in the shape of floods and droughts. The efforts should be augmented by prudent policies of creating new dams and local storage facilities. To the contrary, Pakistan has witnessed a strange complacency and lack of …
