Mn, Ti, Fe EFFECT ON HOT SHORTNESS OF Al-Cu-Mg SYSTEM ALLOY LOCATED IN PHASE REGION α-S

摘要

Using the example of model alloy from phase region (X-S of aluminium angle of system Al-Cu-Mg, the effect of additions Mn ( 0 ... 1%), Ti (0 ... 0.5%), and Fe (0.15 ... 0.6%) on hot shortness is shown. Use of mathematic planning and of experimantal results processing made it possible to plot diagrams of distribution of hot shortness level lines of model alloy investigated compositions in relation to transition metal addition content in them.
