The Effect of Gadolinium on the Microstructures and Charpy Impact Properties of Super Duplex Stainless Steels

open access: yesMetals, 2018
Super duplex stainless steels (SDSSs), exhibiting excellent strength and corrosion resistance, serve as the attractive materials in a variety of industries.

Hair casts

open access: yesIndian Dermatology Online Journal, 2014
Hair casts or pseudonits are circumferential concretions, which cover the hair shaft in such a way that, it could be easily removed. They are thin, cylindrical, and elongated in length. We present an unusual case of an 8-year-old girl presenting with hair casts. Occurrence of these is unusual, and they may have varied associations.

Creep Properties and Deformation Mechanism of Additively Manufactured NiAl‐CrMo Composites

open access: yesAdvanced Engineering Materials, EarlyView.
Additively manufactured NiAl‐CrMo composites contain numerous interfaces and cell boundaries that control their creep response. At 700°C under high applied stress, creep is dominated by dislocation‐controlled power‐law mechanisms. At 800°C–900°C and lower stresses, creep is primarily diffusion‐controlled along cell boundaries.

Micromechanistic analysis of fatigue in aluminium silicon casting alloys [PDF]

open access: yes, 2007
Due to increasingly stringent environmental legislation, there is a requirement for lower emissions and greater overall efficiency of light vehicle diesel (LVD) engines.

Recycling of NiTi Shape Memory Alloys: Fundamental and Technological Aspects of a Vacuum Induction Melting Processing Route

open access: yesAdvanced Engineering Materials, EarlyView.
The present study investigates recycling of NiTi shape memory alloys via vacuum induction melting. An ingot was synthesized from elemental Ni and Ti and subjected to three subsequent remelting cycles. Remelting increases process durations and impurity levels and adversely affects microstructures and functional properties.

Validation of Energy Saving Novel Single Shot Melting Process for Foundry Industry [PDF]

open access: yes, 2013
Casting is a metal forming process: Pouring the melt metal into a desired shaped mould wait it solidifies. It is often used to manufacture complex parts, which are too expensive or time consuming to produce by other methods.

Deformation and Crack Initiation in Ferrite/Cementite System at Ultra-High Strain Rate: Effects of Temperature and Loading Direction from Molecular Dynamics Simulations

open access: yesCrystals
The present study employed molecular dynamics (MD) simulations to investigate the deformation behavior of a ferrite/cementite (α-Fe/Fe3C) dual-phase system under ultra-high strain rate conditions. A systematic examination was conducted to investigate the

Soft Mechanical‐Electrical Logic Using Liquid Metal‐Filled 3D‐Printed Architectures

open access: yesAdvanced Engineering Materials, EarlyView.
We present 3D‐printed soft mechanical–electrical logic elements that use liquid metal–filled silicone tubes actuated by thermoplastic polyurethane/polylactic acid (TPU/PLA) architectures to produce Boolean operations. Complementary normally open and normally closed unit cells perform repeatable binary transitions and can be combined into more complex ...

Experimental Characterization and Constitutive Modeling of the Effect of Prior Inelastic Strain on the Viscoplastic Behavior of AD730 at 700 °C

open access: yesAdvanced Engineering Materials, EarlyView.
This study shows that superalloys used in aircraft engine disks become much more prone to deformation at high temperatures if they have been strained during manufacturing. This effect increases with the level of prior strain but eventually reaches a limit.

A Study on CAE Technology for Casting [PDF]

open access: yes, 2010
More than 500 software for the casting simulation were sold, but few of them were used in the foundries. This study shows the easy way to measure some physical properties in the small foundry and to fit the simulation to the production, and also shows ...
