INVESTIGATION ON STRENGTH AND MICROSTRUCTURAL EVOLUTION OF POROUS CU/CU BRAZED JOINTS USING CU-NI-SN-P FILLER

Porous Copper (Cu) was brazed to Cu plates using Cu-9.7Sn-5.7Ni-7P amorphous filler metal.The effects of brazing parameters on the porous Cu and brazed joints were investigated.The furnace brazing temperatures employed were 660 °C and 680 °C, and the holding times were 10 and 15 esee rb3 min.After brazing, the microstructure was analyzed

Primary school extracurricular activities are additional activities of the compulsory learning process that must be possessed by students so that they can develop their talents, skills, and also characterize elementary school children as a provision in their lives.The purpose of this esee rb3 study is to describe the extracurricular activities of e
