Title: | The production technology of new welding Al-Fe-Cr alloys in which aluminum matrix reinforced nanokvazikrystalichnymy shares for application at 300 C |
Type of product: | Release of new product: material |
Description: | The compositions and production technology of fundamentally new Al-Fe-Cr alloys with matrix (grains size is 200 - 500 nm) reinforced by nanoquasicrystalline particles with size 40-200 nm and volume fraction is 40%. For the first it was shown that the plasticity of the alloys (up to 5% at room temperature) is explained by phase quasicrystal - approximant crystalline phase in the process of deformation. The production technology of new alloys consists in consolidation of water atomized powders by extrusion. Al-Fe-Cr alloys are ready for implementation at the metallurgical enterprises. |
Technical advantages: | Elaborated in IPMS of NASU alloys have the greatest strength at elevated temperatures up to 300 C among all known wrought aluminum alloys (UTS = 350 MPa) and plastisity at room temperature 5%. Welding technology of elaborated Al-Fe-Cr alloys with saving their unique structure, which provides high strength of weld at bending tests up to 910 MPa is firstly developed in PWI of NASU |
The economic benefits: | Lower cost of obtaining alloys, absence of expensive elements in the chamical compositions of elaborated alloys |
The impact on the environment. Environment: | Due to use of high pressure water atomization, production of quasicrystalline powders is environmentally friendly |
