the effects of high temperature homogenization and low temperature annealing treatments on the microstructure and magnetic properties of sintered magnets of an nd17fe76.5b5cu1.5 type alloy have been investigated. the microstructure of the as-cast alloy, consisted of three phases including a nd2fe14b1 (2:14:1- type) matrix phase cu-containing nd-rich phase and free α-iron. the as-sintered magnet...

Abstract In this study, the structure and mechanical properties of near-eutectic refractory Al 24 Cr 11 Nb Ti 37 Zr 17 , 20 25 10 28 15 22 (at.%) high entropy alloys were investigated. Both had a hypoeutectic structure, while alloy hypereutectic one. The proeutectic phase in was ordered B2 – C14 Laves phase. all three alloys, eutectic regions possessed fine lamellar composed mixture phases. den...

Sn-3.0Ag-0.5Cu (SAC305) alloy is the most widely used solder in electronic assemblies. However, issues associated with cost and drop/shock durability have resulted in a continued search for alternative solder alloys. One approach to improve the drop/shock reliability has been to reduce the silver content in Sn-AgCu alloys. Another approach is doping Sn-Ag-Cu solder with additional elements. Mor...

Treatment is an operation or combination of operations involving typical heating and soaking at a temperature for a period of time and methods. The aim is to obtain a desired predetermined property like hardness. Knowing the hardness of any metal or alloy is important, as this value gives you an indication of its ability to form and maintain a shape and is also a guide to its durability. To ens...
