Block Magnets with Uniform Core–Shell Microstructure Regenerated from NdFeB Grain Boundary Diffusion Sheet Magnets [PDF]
The grain boundary diffusion (GBD) process is currently the relatively effective method for utilizing heavy rare earth (HRE) elements in NdFeB magnets, especially for magnetic sheets.

Structural and magnetic properties of chemically synthesized yttrium-substituted nickel nanoferrite [PDF]
In this paper, yttrium-substituted nickel ferrite (NiY2xFe2-2xO4) nanostructures were synthesized via the co-precipitation method with different concentrations of yttrium (x = 0.00, 0.02, 0.06, and 0.12 %, where x is the dopant concentration in molar ...

Relationship between coercivity and stress of X80 pipeline steel
The operation environment along the long-distance oil and gas pipelines is complex, and the abnormal external load during pipeline operation may lead to local stress concentration, which will increase the operation risk of pipeline.The coercivity-based ...

What makes Law Coercive when it is Coercive [PDF]
Most legal and political philosophers agree that typical legal systems are coercive. But there is no extant account of what typically makes typical legal systems coercive when they are coercive. This paper presents such an account and compares it with four alternative views. Towards the end I discuss the proposed account’s payoffs.

Coercion is used by one government (the “sender”) to influence the trade practices of another (the “target”). We build a two-country trade model in which coercion can be exercised unilaterally or channeled through a “weak” international organization without enforcement powers.

Most frequently asked questions about the coercivity of Nd-Fe-B permanent magnets
Physically, the coercivity of permanent magnets should scale with the anisotropy field of ferromagnetic compounds, HA; however, the typical coercivity values of commercial polycrystalline sintered magnets are only ~0.2 HA, which is known as Brown’s ...
