Advanced 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.

Advanced Engineering Materials, EarlyView.A novel workflow for investigating hydride vapor phase epitaxy for GaN bulk crystal growth is proposed. It combines Design of experiments (DoE) with physical simulations of mass transport and crystal growth kinetics, serving as an intermediate step between DoE and experiments.

Advanced Engineering Materials, EarlyView.Coarse‐grained (left) and atomistic (right) models of the shape memory polymer ESTANE ETE 75DT3 are shown schematically. The two representations bridge molecular detail and mesoscopic description. Both models capture shape memory behavior, linking segmental mobility and conformational relaxation of anisotropic chains to macroscopic recovery, and ...

Influence of Geometric Design on Mechanical Performance of Auxetic Metastructure
Advanced Engineering Materials, EarlyView.Strategic geometric reinforcement transforms auxetic performance. This study evaluates 3D‐printed arrowhead metastructures, revealing that a modified design with local ring reinforcement suppresses premature failure to achieve superior energy absorption and structural efficiency.

Neutrosophic Set Approach for Characterizations of Left Almost Semigroups [PDF]
Neutrosophic Sets and Systems, 2016 In this paper we have defined neutrosophic ideals, neutrosophic interior ideals, netrosophic quasi-ideals and neutrosophic bi-ideals (neutrosophic generalized bi-ideals) and proved some results related to them.

A note on Quasi and Bi-ideals in Ternary semigroups
International Journal of Mathematics and Mathematical Sciences, 1995 In this paper we have studied the properties of Quasi-ideals and Bi-ideals in ternary semi groups. We prove that every quasi-ideal is a bi-ideal in T but the converse is not true in general by giving several example in different context.

Quasi-Ideals and BI-Ideals on Semigroups and Semirings [PDF]
, 2007 In this thesis, we introduce some concepts of semigroups and semirings, as quasi-ideals, bi-ideals, regular elements and regular semigroups and semirings Also, we shall introduce some semigroups whose sets of bi-ideals and quasiideals coincide.

Quasi-complete intersection ideals of height 2 [PDF]
, 1998 The paper examines some relationships between minimal generating sets of prime ideals of height 2, which are quasi-complete intersections. By characterizing the ideals p(n1, n2, n3) of monominal curves in Pk3 with μ(p(n1, n2, n3)) = 4, which are quasi ...

Precipitation Simulations of the O‐Phase in Ti2AlNb Alloys Processed by Laser Powder Bed Fusion
Advanced Engineering Materials, EarlyView.Simulated and experimental evolution of the O‐phase volume fraction during postprocessing of a Ti‐21Al‐25Nb (at.%) alloy processed by laser powder bed fusion. With results of sensitivity to input parameters from a thorough and quantified analysis, the interfacial energy matrix/precipitate is the most relevant input parameter for the simulation of the O‐
