给出了基于Al-Mg-Sc系的新型01515、01523、01535、01545、01570和01571可变形可焊合金的数据。这些合金彼此不同，主要是镁含量不同，属于不可热处理合金家族。热加工或退火态的变形Al-Mg-Sc合金半成品的性能(特别是屈服强度)明显高于相同镁含量的常规Al-Mg合金半成品。强化既与二次Al3Sc颗粒的直接强化作用有关，又与稳定的非再结晶组织的形成有关。在Al-Mg-Sc合金中，镁含量约为6%的01570合金应用最为广泛。01570合金热加工或退火半制品的屈服强度为300Mpa，而类似的无Sc合金半制品的屈服强度约为180Mpa。讨论了新型合金在各种结构生产中的应用前景。爱思唯尔科学公司出版。
Data on new 01515, 01523, 01535, 01545, 01570 and 01571 wrought weldable alloys based on the Al-Mg-Sc system are presented. These alloys differ from each other, mainly, by magnesium content and belong to the family of non-heat-treatable alloys. Wrought Al-Mg-Sc alloy semiproducts as-hot worked or as-annealed show much higher properties (especially yield strength) than those made from conventional Al-Mg alloys with the same magnesium content. Strengthening relates to both direct strengthening effect of the secondary Al3Sc particles and development of a stable nonrecrystallized structure. Of Al-Mg-Sc alloys, 01570 alloy containing about 6% Mg has found the widest application. Yield strength of hot worked or annealed 01570 alloy semiproducts is at a level of 300 MPa, while yield strength of semiproducts made from a similar scandium-free alloy is about 180 MPa. Prospects of the usage of the new alloys for production of various structures are discussed. Published by Elsevier Science S.A.
