Corrosion behavior of microwave-sintered austenitic stainless steel composites

Effect of sintering temperature on the mechanical and electrochemical properties of austenitic stainless steel

“…The compacts sintered under solid state at 1200 and 1300 1C exhibited less shrinkage than the samples sintered under supersolidus state at 1400 1C whose densification was greatly enhanced due to the capillary action of a high diffusivity liquid phase and viscous flow sintering mechanism [25]. Similar densification behavior was reported by others [16,17].…”

“…The liquid forming inside the particles spreads to the particle contacts and results in a capillary stress induced pore filling and increased diffusion kinetics thereby enhancing densification [14]. Previously, researchers [15][16][17] have compared the electrochemical response through potentiodynamic polarization of 316L steel at 1200 1C and 1400 1C. There is not much literature available on the investigation of Electrochemical Impedance Spectroscopy (hereafter referred to as EIS) studies of super solidus sintered samples.…”

Corrosion behaviors, mechanical properties and microstructure of the steel matrix composites fabricated by HP–HT method

“…This wide range of applications is certainly due to their excellent properties, such as the high resistance to corrosion and abrasion, high resistance to oxidation at elevated temperatures and satisfactory strength [1][2][3]. Powder metallurgy creates opportunities for the manufacture of small parts with complex shapes.…”

Effect of heating mode and Y2O3addition on electrochemical response on austenitic and ferritic stainless steels

“…13,14 Among ferrous systems, Anklekar et al 15,16 and Raja Annamalai et al 17,18 have recently demonstrated that steel powder compacts can be effectively sintered in a microwave furnace and yield higher mechanical properties as compared with conventional sintering. Saitou, 19 Panda et al 20 and Padmavathi et al 21 have demonstrated that both austenitic as well as ferritic stainless steel compacts can be consolidated using microwaves. Padmavathi et al 21 have shown that 316L-YAG composites can be prepared by microwave sintering and have a superior mechanical and corrosion response.…”
