Machinability Enhancement of Lead-free Brass Alloys

Machinability of Experimental Ti-Cu Alloys

This study is an investigation of the machinability of experimental Ti-Cu alloys (2, 5, and 10mass% Cu) as new dental titanium alloy candidates for CAD/CAM use. The alloys were slotted with a vertical milling machine and carbide square end mills under two cutting conditions. Their machinability was evaluated through cutting force using a three-component force transducer fixed on the table of th...

Machinability of experimental Ti-Ag alloys.

This study investigated the machinability of experimental Ti-Ag alloys (5, 10, 20, and 30 mass% Ag) as a new dental titanium alloy candidate for CAD/CAM use. The alloys were slotted with a vertical milling machine and carbide square end mills under two cutting conditions. Machinability was evaluated through cutting force using a three-component force transducer fixed on the table of the milling...

Review on Machinability of Titanium Alloys: the Process Perspective

Titanium alloys are widely used in the engineering field, namely in the aerospace, automotive and biomedical parts, because of their high specific strength and exceptional corrosion resistance. However, the machinability of titanium alloys is difficult due to their low thermal conductivity and elastic modulus, high hardness at elevated temperature, and high chemical reactivity. This article rev...

Board Level Reliability Comparison of Lead Free Alloys

Board level reliability testing was used to compare six lead free alloys to tin-lead eutectic using a 98 ball Wafer Level Chip Scale Package (WLCSP). The component had a 0.5mm Ball Grid Array (BGA) pitch, and Al/NiV/Cu pad metallization. Thermal cycling (4 conditions), cyclic bend (2 conditions), cyclic drop (3 conditions), and solder joint array tensile testing (3 conditions) were utilized to ...
