“…Температура операции старения выбрана в соответствии с температурой соответствующей выделению второй фазы из пересыщенного твердого раствора железомедного сплава. После закалки при данных температурах имеет место упрочнение железного каркаса, а последующее старение позволяет при сохранении прочности каркаса повысить пластичность материала [10][11][12].…”

“…Currently, research on copper-infiltrated sintered steels mainly focuses on the composition and content of copper infiltrant. It also involves optimizing the copper infiltration process, which includes parameters such as copper infiltration temperature, sintering atmosphere, infiltration time, pre-sintering, and heat treatment [5][6][7][8][9][10][11][12][13][14][15]. Limited research exists on the influence of the pore structure of the sintered steel skeleton on the copper infiltration process.…”

Copper-infiltrated sintered steel is a prominent area of research in the field of powder metallurgy, with a particular focus on enhancing impact toughness. In this study, sintered steels with varying pore structures were prepared using iron powders and infiltrated with copper to investigate their impact toughness. The results indicate a significant improvement in the impact toughness of the sintered steels with concentrated iron particle sizes. The density of the samples increased from 6.85g/cm³ to 7.55g/cm³ through copper infiltration. The large copper-phase sample with the particle size of 150μm exhibits an impact toughness as high as 41.09 J/cm², and its fracture morphology mainly shows transgranular fractures of large iron particles. It is 1.5 times that of the sample made from commercial iron powders which measured 27.46 J/cm². This enhancement is primarily attributed to the precipitation of γ-Fe within the large copper phase, thereby enhancing the copper phase and transferring the load into large iron particles. A brief mechanism of γ-Fe precipitation in the large copper-phase has been provided.

This paper describes some properties and structure formation features of the MMCs obtained by the infiltration of iron–carbon skeletons with tin bronze. It has been shown that the formation of the MMC structure depends on the composition and porosity of the iron skeleton. During the infiltration of a green skeleton, a redistribution of carbon and nickel occurs; outer layers have less carbon and more nickel; and carbon content is higher in the centre of the particles. With higher carbon content of the iron skeleton, the hardness and wear resistance properties of MMCs increase. The strength and wear resistance properties of the MMCs obtained by the infiltration of a green skeleton are higher compared to the sintered one regardless of the carbon content in the skeleton.
