目前,我国铝加工工业在铸锭生产方面,正在试验与推广新的一代中间合金——Al-Ti-B晶粒细化剂——作为晶粒细化剂。这标志着我国在变形铝合金铸锭晶粒细化方面,正在赶上世界先进水平。但有几个问题值得我们注意,尤其是关于合金中残存钛和(或)硼对晶粒细化效果的影响。国外在采用这类新型细化剂大约五年之后,才注意到这个问题与进行
At present, China’s aluminum processing industry in the ingot production, is testing and promotion of a new generation of master alloy - Al-Ti-B grain refiner - as a grain refiner. This marks our country in the deformation of aluminum alloy ingot grain refinement, is catching up with the world advanced level. However, there are several issues that deserve our attention, particularly with regard to the effect of the residual titanium and / or boron in the alloy on grain refinement. About five years after the introduction of this new type of refiner, foreign countries noticed this issue and proceeded
