On the basis of our past research on Fe-Mn-Al system, a new Ni-Cr-free cryogenicnon-magnetic steel-15Mn26Al4 has been developed. The steel shows stable aus... 叶基石 - 《金属学报》 被引量: 33发表: 1977年 Strange Attractors in an Antiferromagnetic Ising Model The three-site antiferromagn...
Phase equilibria were investigated in the Al–Pd–Mn phase diagram in the region where quasicrystals and approximant phases form. With respect to previous thermodynamic studies, the extents of the liquidus phase fields of several approximant phases are either established or precisely determined. In part...
