金属学报(英文版)

The critical diameter of γ'-phase(dc) is an important microstructural characteristic.Relationships among the critical diameter(dc).the volume fraciton(f),the antiphase domain boundaryγenergy(APBE) ofγ'-phase and the shear modulus(G) of precipitation strengthening Ni-base alloys have been studied in this paper.The results show that the alloys have the strongest age-hardening effects but the lowest ductility corresponding to the critical size of γ'-phase.The impact ductility of the alloys relates to γ'precipitation induced volume distortion in the matrix.

LIU Chengjun , SHI Peiyang , ZHANG Dayong , JIANG Maofa

钢铁研究学报(英文版)

A great amount of ferrous tailings and slag cause severe damage to the ecological environment, which must be reclaimed and utilized. The composition, type, and characteristics of ferrous tailings and slag in China were introduced. The research status and the application outlook of glass ceramics made from ferrous tailings and slag were discussed. Glass ceramics made from ferrous tailings and slag can be applied to various fields, and it will be environmentally conscious materials in the 21st century.
