メルトドラッグ法によるAl-12mass%Si合金急冷凝固クラッド材の作製

抄録

This study was attempted to produce rapidly solidified clad strip by a melt drag process and to examine the clad strip properties. Roll speed V and cooling length L were chosen as principal producing factors. Clad strips consisting of base and overlay strips rigidly bonded with clear bonding interface are produced under the condition where roll speed V was varied from 30 to 70m/min and cooling length L was varied from 25 to 100mm. Clad strips of base and overlay strip both rapidly solidified are produced by cooling length between 75 and 100mm with a constant rolling velocity 50m/min.
