| 摘 要： | 对LD 10 CS铝合金厚板在热的碱性水溶液中化铣时出现端晶腐蚀的原因及影响因素进行了研究。结果指出它主要是由于材料中铜等元素的显微偏析造成的。材料的热处理状态等亦对它有影响。熔铸时采取减轻元素偏析的措施后,有效地消除了这种腐蚀。

| Abstract: | The end grain attack of LD10CS aluminium alloy plates during che-
mical milling in hot aqueous solution of sodium hydroxide has been studied. The
results show that the microsegregation of some components, i.e. Cu, Si etc., is the
main reason of the end grain attack, and it is affected by the conditions of heat
treatment as well. The end grain attack significantly minimizes while some technical
measures which are beneficial to the reduce of segregation were taken during melting
and casting. |
