The objective of this research is to investigate microstructure and mechanical properties of brass welded by diffusion welding process. The diffusion welding (DW) of brass welded over lap joints bonding parameters were pressure at temperature 500 650 and 800 0C contact pressure of 12 MPa and holding time for 60 minutes respectively. The microstructure mechanical properties and behaviour during bonding were investigated. The results show that in weld zone (Bond Line) diffusion of atom the brass significantly. The mechanical properties after diffusion welding process increased higher temperature

The purpose of the research was to study the exciting permanent-magnetic-field affecting to the Bean Sprout growing. The comparison of control-group (or unexcited seed) of the Chainat-72 seed and exposure-group seed where is the excited by the 1.6-Tesla permanent-magnetic-field of 15 30 45 and 60 min has been done. The exciting permanent-magnetic-field affecting to the Bean Sprout growing is analyzed by statistical analysis. The findings revealed that: by excited seed the maximum grow-up rate or average weight of Bean Sprouts was 24.82 %.
