) 摘要:The electrode alloys La0.7,Mg0.3Co0.45Ni2.55-xFex (x = 0, 0.1, 0.2, 0.3, 0.4) were prepared by casting and rapid quenching. The influences of the substitution of Fe for Ni on their cycle... in the as-quenched ahoy are significantly refined, and the lattice constants and the cell volumes of the alloys are obviously enlarged. 关键词:La-Mg-Ni system electrode ahoy; substituting Ni with Fe; rapid quenching......
Gas Quenching Small Components Paul Stratton1 (1.BOC, Sheffield, UK) 摘要:Gas quenching is an environmentally friendly and effective way of quenching components. However it has not been possible to apply it to small components because of the difficulties of jigging. A method of gas quenching such small components is described in which they are levitated in a confined gas stream. The method......
