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

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.

SHADOW ECONOMY AND ITS IMPACT ON THE ECONOMY

Bulletin of Korkyt Ata Kyzylorda University, 2021
Бұл мақалада қазіргі кездегі көлеңкелі экономиканың әлеуметтік-мәдени себептері мен көлеңкелі экономиканың көлемін арттырып отырған жағдайлар қарастырылады. Себебі көлеңкелі экономика бірнеше онжылдықтан бері зерттеліп келе жатқанымен, оны нақты талдайтындай анық түсінік әлі қалыптасқан жоқ.

Electrochemical Behavior of Flame‐Sprayed Sc‐Doped AlCoCrFeMo High‐Entropy Alloy Coatings in 3.5% Sodium Chloride Solution

Advanced Engineering Materials, EarlyView.
Scandium (Sc)‐doped AlCoCrFeMo HEA coatings are fabricated via flame spraying with 0.1, 0.3, and 0.5 wt% Sc additions. Among these, the HEA‐Sc0.3 coating exhibits the highest corrosion resistance, indicated by a more positive corrosion potential and lower current density.

Feasibility of Nitrogen as a Carrier Gas for Inconel Cold Spray in Hydropower Application

Advanced Engineering Materials, EarlyView.
N2, despite being nearly two orders of magnitude cheaper than He, is a feasible carrier gas for cold spray Inconel coatings in hydropower repair applications when higher gas temperature and pressure are used. Reducing powder size significantly improved cavitation resistance, while the addition of fine chromium carbide particles further enhanced erosion

The Shadow Economy and Shadow Economy Labor Force: What Do We (Not) Know? [PDF]

SSRN Electronic Journal, 2011
In this paper the main focus lies on the development and the size of the shadow economy and of undeclared work (or shadow economy labor force) in OECD, developing and transition countries. Besides informal employment in the rural and non-rural sector also other measures of informal employment like the share of employees not covered by social security ...

Influence of Scan Strategies in Electron Beam Powder Bed Fusion on Solidification, Microstructure, and High‐Temperature Compressive Properties of γ′‐Strengthened Inconel 738LC

Advanced Engineering Materials, EarlyView.
Experiments and thermophysical simulations were conducted to investigate the electron beam powder bed fusion electron beam (PBF‐EB/M) process for the γ′‐strengthened nickel‐based superalloy Inconel 738LC. The results demonstrate the impact of process‐induced microstructural variations on high‐temperature mechanical behavior, providing a basis for ...

The Analogy of Shadow Economy and Officially Non-Observed Economy

Socialiniai Tyrimai, 2019
The study examines the analogy of the concepts of shadow economy and non-observed economy. This study is relevant due to the fact that the studies related to shadow economy face the diversity of concepts: it seems that the same phenomenon – companies ...
