| Research Abstract |
Grain refinement performance of Al cast using machining chips and new grain refiner contains Ll_2 type Al_5CuTi_2 intermetallic particles are studied. It is found that the machining chips and Ll_2 type Al_5CuTi_2 intermetallic particles act as the grain-refiner, since the lattice disregistry towards Al is zero and 3%, respectively. Finite element analysis of severe plastic deformation of difficult-to-work material by novel equal-channel angular pressing at ambient temperature is also carried out. This novel equal-channel angular pressing method can be applied for fabrication of grain refiners.
