Wetting and spreading ability of Ag-Cu-Zn filler and Ag-Cu-P filler on copper surface under heat treatment furnace was studied. The microstructures of brazed joints of Ag-Cu-Zn and Ag-Cu-P filler under the same parameter were also observed. The microstructure shows that the wetting ability of Ag-Cu-Zn filler on the copper surface is better than Ag-Cu-P and its structure is uniformed and regulated. It is founded that there were obvious dissolution and diffusion between base metal and filler for the copper/Ag-Cu-Zn/copper joint, there were white and black eutectic structure formed in the joint interface.

Electric Heat

In order to contribute in the research activities related to heat treatment of metals and other engineering materials, a laboratory scale heat treatment furnace is essentially required. Among several other types of furnaces, electric heat treatment furnace is said to be most useful. It is provided with a programmable controller which precisely controls heating rate, soaking time and cooling rate. The controller also helps in keeping the heat treatment safe by emergency turnoff facility. This manuscript reports the indigenous designing and development of electrical heat treatment furnace, which not only provides enormous learning to fresh graduates but also saved a handsome amount, which could have spent in purchasing same article from commercial market. In this paper, the sequential procedure of furnace designing and development is being shared with the engineering community so that the researchers of under developed countries may save their esteemed educational and research funds.Journal of the Institute of Engineering, 2016, 12(1): 151-161
