Influence of atmosphere and carbon contamination on activated pressureless infiltration of alumina–steel composites

Preparation and Properties of Cu-10Sn Alloy Infiltrated 316L Stainless Steel Composites

“…Pressureless infiltration offers an industrially preferred route as infiltration can be done without application of an external pressure. However, capillary forces have to be used to promote infiltration [7]. Therefore, 1% (in mass percent) Cu-10Sn alloy powder was added into the 316L stainless steel powder to modify the wetting.…”

“…This technique is being used widely increasingly from the 1950s [6]. In general, pressureless infiltration offers an industrially preferred route as infiltration can be done without application of an external pressure [7]. Infiltration was performed by penetration of the molten metal/alloy with a low melting point through the pores of a self-standing porous skeleton, which has a controlled porosity of 10%~30%.…”

Influence of microstructural features on the impact toughness of infiltrated Al2O3|P-steel composites

“…8). From previous work it is assumed that Ti reacts with carbon residual after debinding process [32]. Since the secondary Ti-rich phases seem to be depending on the matrix steel, it is assumed that carbon and nitrogen derives from the chemical composition of the given steel to form TiC-or TiN-phases respectively.…”

Preparation and Interface Investigation of Fe/Al2O3P Composite Activated by Ni and Ti

“…Besides, the TEC of reaction products is usually different from the TEC of reactant, so the additive elements may improve the thermal matching property when the TEC of interfacial reaction product or interphase with a certain thickness is in the middle of the TEC of phases on two sides at interface . And Bahraini et al investigated the effect of Ti and Si at the Al 2 O 3 /steel interface under different infiltration atmospheres and found that both of them could improve the infiltration quality …”
