3 Metallic Materials and Processes New Materials for

Research on the development of new high-strength, high-toughness, corrosion-resistant steels for landing gear materials has been a subject of intense recent interest. Improved Ni-Co, low-carbon steels (most notably Aermet 100 and AF1410), have excellent combinations of properties and are developed to the point where they are now being specified as replacements for the standard landing gear steels A Review of Lithium-Ion Battery Thermal Management optimization methods. Moreover, because low power consumption, a high temperature regulation capacity, and excellent temperature uniformity are desired for every battery thermal management system, we also present control strategies that can contribute to thermal management. It is

A Review on Fatigue Life Prediction Methods for Metals

Metallic materials are extensively used in engineering structures and fatigue failure is one of the most common failure modes of metal structures. Fatigue phenomena occur when a material is subjected to fluctuating stresses and strains, which lead to failure due to damage accumulation. Different methods, including the Palmgren-Miner linear damage rule- (LDR-) based, multiaxial and variable Accelerated Aging of Materials and Structures:The Effects Findley and Lai (1978) and Cho and Findley (1984), for example, developed a viscous-viscoelastic model with a replacement of a temperature-compensated time for actual time, using tension and torsion data for alloy 2618-T61 in the range of temperatures of 200°C (392°F) to 230°C (446°F).

EPRI Home

The Electric Power Research Institute (EPRI) conducts research, development, and demonstration projects for the benefit of the public in the United States and internationally. As an independent, nonprofit organization for public interest energy and environmental research, we focus on electricity generation, delivery, and use in collaboration with the electricity sector, its stakeholders and Experimental Development of JohnsonCook Strength Mar 27, 2020 · Abstract. JohnsonCook (JC) high-temperature strength material models have been widely used in finite-element analysis (FEA) to solve variety of hot rolling problems. Herein, the temperature- and strain rate-related parameters of JC model are experimentally calibrated for eight different steel grades including SAE 1018 and SAE 1045, structural steels (ASTM A572-60, ASTM Materials for Sustainable Energy - World ScientificHowever, the necessity for high operating temperatures (8001,000 °C) has resulted in high costs and materials compatibility challenges As a consequence, significant effort has been devoted to the development of intermediate-temperature (500700 °C) SOFCs.

Technical properties of NEXTREMA® heat-resistant glass

NEXTREMA® exceeds all expectations when it comes to temperature resistance. The material can withstand both extremely high and low temperatures, offering outstanding resistance up to 950 °C. From white hot to ice cold and back again, quick changes in temperature will have little impact on this heat resistant glass-ceramic, minimizing thermal Unified constitutive materials model development and Unified constitutive material models were developed for structural analyses of aircraft gas turbine engine hot section components with particular application to an isotropic material used for combustor liners.
