MODULUS OF ELASTICITY AND MODULUS OF RUPTURE OF ELECTRICAL PORCELAIN

open access: yesJournal of the Ceramic Association, Japan, 1937
Measuring the modulus of elasticity and that of rupture for electrical porcelain with the small cross sectional area, the following results have been obtained.1. When the grain size of green body is reduced, the modules of rupture and the modulus of elasticity become larger, but the increase of the latter is smaller when compared with that of the ...

Micromechanical Characterization of 316L‐V4E Steel Transitions Produced by Electron Beam Powder Bed Fusion with Dual‐Hopper Alternating Layer Strategy

open access: yesAdvanced Engineering Materials, EarlyView.
This work applies High‐Speed Nanoindentation to study multi‐material transitions in powder bed fusion–electron beam melting components. The aim is to assess the mechanical gradients and interfacial behavior between American iron and steel institute 316L stainless steel and V4E tool steel in additively manufactured structures.

Micromechanical Insights into Sinter‐Based Additively Manufactured NiTi with Nb as a Sintering Aid

open access: yesAdvanced Engineering Materials, EarlyView.
This study investigates the microstructural and micromechanical behavior of NiTiNb made through filament‐based materials extrusion via chemically correlated nanoindentation. B19' remnants from the original powder lead to Nb gradients within NiTiNb grains due to the short sintering times required in liquid‐phase sintering.

Deformation Behavior of Optical Ceramic Nanomultilayers: The Role of Aperiodicity

open access: yesAdvanced Engineering Materials, EarlyView.
Ceramic nanomultilayers demonstrate optical and mechanical behavior tunability through aperiodicity. Within the studied systems, optically optimized coatings exhibit an average ultraviolet, visible, and near‐infrared spectral transmittance above 90%.

Programmable Reconfiguration of Hybrid 4D Chiral Metamaterials via Mechanical and Thermal Stimuli

open access: yesAdvanced Engineering Materials, EarlyView.
A class of hybrid chiral mechanical metamaterials is designed to achieve programmable reconfiguration through soft networks, hinges, and bilayer joints integrated with rigid units. Responsive to mechanical and thermal stimuli, these structures exhibit large volume changes, tunable deformation pathways, and both positive and negative thermal expansion ...
