Surface Treatment of Powder Metallurgical Compacts
Introduction Powder metallurgy (p/M) is a rapidly expanding technology for manufacturing of structural parts. The PA4 process provides economical as well as technical benefits over conventional processing of wrought material. It is possible to fabricate high quality, complex parts to close tolerances without machining. The energy consumption is low and the material utilisation and productivity ...
متن کاملMagnetoresistance of Chromium Dioxide Powder Compacts
Cold-pressed powders of the half-metallic ferromagnet CrO2 are dielectric granular metals. Hysteretic magnetoresistance with maxima at the coercive field arises from interparticle contacts. Dilution with insulating antiferromagnetic Cr2O3 powder reduces the conductivity by 3 orders of magnitude, but enhances the magnetoresistance ratio which reaches 50% at 5K. The negative magnetoresistance is ...
متن کاملcontrol of the optical properties of nanoparticles by laser fields
در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...
15 صفحه اولReduction of Surface hr~ >ion Caused by Helium Blistering in Sintered Beryllium and Sintered Aluminum Powder
Studies have been conducted to find Materials with microstructures which Minimize the formation of blisters. A promising class of materials appears to be sintered metal powder with small average grain sizes and low atomic number Z. Studies of the surface erosion of sintered aluminum powder (SAP 895) and of aluminum held at AOO'C due to blistering by 100 keV helium ions have been conducted and t...
متن کاملSynthesis of calcium carbide-derived carbon by mechanochemical reaction of calcium carbide with sulfur, iron sulfide and zinc oxide
In the present work, we report a novel design and preparation for the mechanochemical synthesis of calcium carbide-derived carbon (CaC2-CDC) at ambient temperature. Thermodynamic calculations confirmed the possibility of calcium carbide-derived carbon formation by the reaction of calcium carbide with sulfur, iron sulfide and zinc oxide at ambient temperature. The CDCs were synthesized by the ba...
