The present application provides a method for preparing a rare-earth permanent magnetic material with grain boundary diffusion using composite target by vapor deposition, in which the composite target is evaporated and attached to the surface of the NdFeB magnet, and in which medium-high temperature treatment and low temperature aging treatment are employed, resulting in that the coercive force of the magnet is improved significantly and the remanence and the magnetic energy product substantially are not reduced. The advantageous effects of the present application is as follows: the coercive force of the magnet is improved, and meanwhile the defects such as melting pits and crystal grain growth and the like caused by high temperature treatment for the long time are eliminated, and the usage amount of heavy rare-earth is greatly reduced, thereby lowering the cost of the product.

PRESS RELEASE Change in the partnership between ERASTEEL and Heye Special Steel Co., Ltd in China ERASTEEL, a 100% subsidiary of ERAMET, and the Chinese company AT&M (Advanced Technology & Materials Co., Ltd) have signed a memorandum of understanding concerning the future of their activities in China in the domain of high-speed steels. ERASTEEL is expected to sell its 10.29% stake in Heye Special Steel Co., Ltd to AT&M, Heye's majority shareholder. The transaction should take place in the second half of 2017, subject to several regulatory approvals, for an amount of 109.5 million yuan, i.e. approximately €15 million. AT&M has also announced that its subsidiary, Heye Special Steel Co., Ltd, intends to sell its 51% stake in HEIML (Heye-Erasteel Innovative Materials Co., Ltd). It is envisaged that ERASTEEL could acquire this stake. Currently, ERASTEEL owns 49% of HEIML's shares. HEIML is a Chinese company based in Tianjin, specialised in bars drawing and wire drawing of high-speed steel. ERAMET is one of the leading global producers of: ERAMET is also developing activities with high growth potential, such as mineral sands (titanium dioxide and zirconium), lithium and recycling. The Group employs nearly 13,000 people in around 20 countries. For more information: www.eramet.com Follow us with the ERAMET Finance mobile app:


COMMUNIQUE DE PRESSE Evolution du partenariat entre ERASTEEL et Heye Special Steel Co., Ltd en Chine ERASTEEL, filiale à 100 % d'ERAMET, et la société chinoise AT&M (Advanced Technology & Materials Co., Ltd) sont parvenues à un accord cadre concernant l'évolution de leurs activités en Chine dans le domaine des aciers rapides. ERASTEEL devrait céder la participation de 10,29 % qu'elle détient dans Heye Special Steel Co., Ltd à AT&M, son actionnaire majoritaire. La transaction devrait intervenir au second semestre 2017, sous réserve de diverses autorisations réglementaires, pour un montant de 109,5 millions de yuan, soit environ 15 millions d'euros. AT&M a par ailleurs annoncé que sa filiale Heye Special Steel Co., Ltd a l'intention de céder la participation de 51 % qu'elle détient dans HEIML (Heye-Erasteel Innovative Materials Co., Ltd). Il est envisagé qu'ERASTEEL se porte acquéreur de cette participation. ERASTEEL possède actuellement 49 % du capital de HEIML, société chinoise basée à Tianjin et spécialisée dans l'étirage et le tréfilage d'aciers rapides.

Patent
Advanced Technology Materials Incorporated and Entegris | Date: 2012-12-06

The present invention provides a fluid filter utilizing a polymeric membrane supports by metallic screens contained in a housing. The supports have apertures through which fluid can pass. The metallic supports are created such that they have at least one surface substantially free from burrs, so as not to damage the membrane. This smooth surface is in communication with the polymeric membrane. One or more indexing protrusions can be added along the circumference to restrict the relative movement between the supports, and to align the apertures of the two supports.
