Failure analysis and flexural behavior of high chromium white cast iron and AISI4140 Steel bimetal beams

Wear and Corrosion Behavior of High-Cr White Cast Iron Alloys in Different Corrosive Media

“…Many engineering applications require materials with excellent resistance to both corrosion and wear [1][2][3][4][5][6][7]. High-Cr white cast irons have excellent wear and corrosion resistance and are inexpensive, and thus have been used for impact coal crusher hammers, pulverizer rings, chute liner, and hardfacing alloys of rolls or molds.…”

“…The carbides presented in the Fe-Cr-C system are (Fe,C) 3 C, (Fe,Cr) 7 C 3 , (Fe,Cr) 23 C 6 , and (Fe,Cr) 3 C 2 [2][3][4]. In many previous studies [4][5][6], the type and form of eutectic carbides change from M 3 C to M 7 C 3 with an increase in Cr content. In unalloyed or low-Cr white cast irons containing below 5 % Cr and up to 2 % C, the eutectic carbides of the M 3 C type in a continuous ledeburitic form (with hardness of HV = 1000) are present.…”

Special features of macro-scale localized plastic deformation in bimetal

“…The ultrasound velocity increases with decreasing inner stress within the materials and decreases with its increase. The plastic flow curve is attributed to the general diagrams described by the Ludwik equation ( ) n y ( 1 ) 040004-2 where ε and σ are the current stress and deformation, σ y is yield strength, θ is the work hardening coefficient; n ≤ 1 is the exponent of deformation hardening in the Ludwik equation. Using the Ludwik equation and representing the loading curve in the functional logarithmic coordinates ) (ln ) ln( 0 e f s s enable us to distinguish the stages in the deformation curve where the index n is constant, changing discretely from segment to segment.…”

“…In connection with this, layered metal composites are widely used. They can be fabricated by combining various metals in monoliths that retain a reliable binding between the components under further technological treatment and in operation [1][2][3]. Bimetals and trimetals belong to these materials, which are composed of two and more metals and alloys.…”

Investigation of structure and heterogeneity of the plastic deformation in bimetal exposed to uniaxial tension

“…Therefore multilayer metal composites become widely used. Such materials can be produced by combining heterogeneous metals into a monolithic composition that preserves a reliable bond between components during further processing and operation [1][2][3][4][5][6]. These materials include bi-and trimetals -multilayer materials consisting of two and more metals and alloys [7,8].…”
