铝合金中的渣—气孔
摘要
文中指出
当合金中含氮量在一定范围内
Al
2
O
3
含量高
试样针孔度也高
ZL104合金加入铝合金除渣除气剂“DSG”
既减少了合金中的Al
2
O
3
含量、又减少金了合的含氢量
从而使针孔率降低。本文也对“渣—气孔”的形成机理作了探讨。
Abstract
The greater the content of A12O3 in aluminium alloys
the higher the rate of pinholes in samples of the alloys under the condition of de-slagging and de-gassing flux "DSG" in ZL104 alloy
the content of A12O3 and hydrogen was decreased so that the rate of the pinholes was decreased. The mechanism of formation for slag-gas holes is studied also.
