摘要：
The (Fe88Si12)(95)Al-5 alloy was prepared by an aluminothermics. The (Fe88Si12)(95)Al-5 alloy is composed of spheroidic alpha-Fe(Si,Al) precipitate with size of 20-50 nm and gamma-Fe(Si,Al) matrix. The yield strength and fracture strain in compression of the (Fe88Si12)(95)Al-5 alloy are 1500 MPa and 23% respectively. The shear bands propagating in the compressive deformation are arrested by the precipitation particles that resulted in large ductility and high strength simultaneously.
