FIELD: process engineering.SUBSTANCE: invention relates to foundry and can be used for production of high-strength iron with globular graphite without structurally free cementite as-cast. Proposed alloy contains the following substances, in wt. %: rare earth metals - 10-20, silicon - 20-30, scandium - 1-3, aluminium making the rest. Foundry alloy comprises 1-3 wt. % of lanthanum in rare earth metal compound.EFFECT: higher mechanical properties, ruled out chill in thick-wall casts.2 cl, 1 ex, 2 tbl |
