Effect of Filler Composition on the Brazing of Alumina to Copper Using Ultrasonic Wave

Khalid M.HAFEZ , Masaaki NAKA

材料科学技术（英文）

An ultrasonic wave was applied during brazing of alumina to Cu. First alumina was metallized by applying ultrasonic wave in braze bath. Then the metallized alumina was brazed with Cu using the same filler alloy. The filler used were Zn-Al alloys and Zn-Sn Alloys. The weight percent of Al in filler w...

Numerical Simulation of Brazing TiC Cermet to Iron with TiZrNiCu Filler Metal

Lixia ZHANG , Jicai FENG

材料科学技术（英文）

The maximum thermal stress and stress concentration zones of iron/TiC cermet joint during cooling were studied in this paper. The results showed that the shear stress on iron/TiC cermet joint concentrates on the interface tip and the maximum shear stress appears on the left tip of iron/TiZrNiCu inte...
