متن کاملJoining Metals Using Semi-Solid Slurries
A method of joining metals with semi-solid slurries is presented. Experiments have been carried out using a model alloy of Sn-Pb to demonstrate the concept. The advantages of this process are a controlled microstructure of the weld, lower post-welding stresses and a small heat affected zone. Tensile tests have been performed, showing a weld strength comparable to bulk material strength. Key fac...
متن کاملLiquid-solid joining of bulk metallic glasses
Here, we successfully welded two bulk metallic glass (BMG) materials, Zr51Ti5Ni10Cu25Al9 and Zr50.7Cu28Ni9Al12.3 (at. %), using a liquid-solid joining process. An atomic-scale metallurgical bonding between two BMGs can be achieved. The interface has a transition layer of ~50 μm thick. The liquid-solid joining of BMGs can shed more insights on overcoming their size limitation resulting from thei...
متن کاملSolid State Process for Preparation of Nickel Oxide Nanoparticles: Characterization and Optical Study
In the present work, we report preparation of NiO nanoparticles with well-defined plate morphology by solid-state reaction of NiCl2∙6H2O and the Schiff base ligand N,N′-bis-(3-methoxysalicylidene)benzene-1,4-diamine), as a novel precursor via solid state thermal decomposition method. This method is a simple and environmentally friendly for preparing t...
متن کاملFuture Direction of Solid State Micro-Joining Applied to Environmentally Friendly Electronic Packaging
近年,低炭素社会を目指すことが叫ばれている.地 球温暖化阻止のためである.二酸化炭素等の温暖化ガ ス排出を抑制するための政策が実施され,2008 年に は,新たに省エネ法も改正された.各事業者の社会的 責任(CSR)はますます大きくなっている.その結果, 製造業での無駄は非常に少なくなり,まさに,乾いた 雑巾になりつつある.一方,民生・運輸事業,個人レベ ルでは,まだまだ「しぼり」が足りない感がある.こ の「しぼり」を増すために,我々の技術イノベーショ ンが必要となろう.商品(製品)の総合エネルギー効 率はかなり良くなってきた.エネルギー効率アップは エレクトロニクス実装技術革新によって支えられてい ると言って過言でない.有害物質フリーで環境負荷低 減の要求は当然のこととして,1990年代後半以降,微 細高密度/三次元化への技術革新が加速している [1]~ [4],当初は,ユビキタス...
