“…Chromium is yet another element known to produce strong surface films; Researchers used this fact in partial explanation of poor casting quality in some of their alloys. Researchers made direct determinations of the influence of surface films on the surface tension of liquid cast iron and found increases of up to 0.5 N/m, considered high enough to be significant with respect to flow in small passages [6][7][8][9].…”

This article presents the results of various studies on the direct effect of fluidity on the quality of castings during the molding process of a liquid alloy, as well as on how ductility can be determined. Methods for measuring readability have also been suggested by many researchers. In addition, various problems encountered during the casting of low-alloy alloys and methods for their detection are considered in detail.

“…1 were obtained by measuring the total hardness of the alloys, which is determined mainly by the hardness of the metal base of the alloy. The presence of carbides with high hardness in the alloy: (Fe, Cr)3 -HV 1080, (Fe, Cr) 7C3 -HV 1240-1550 insignificantly changes the overall hardness of the alloy, but significantly increases its wear resistance, since the hardness of these carbides is equal to or higher than the hardness the most common abrasive is quartz [3,4]. These hard carbides protect the part or specimen from wear (as in this case).…”

This article, by changing the chemical composition of high-chromium 280X29NL cast iron and processing its composition Ti from 0.93% to 1.78%, the elongation strength of highchromium cast iron increased and without affecting the hardness of the alloy, Ti addition was added. 'The structure was improved by swelling. The strength of the secondary carbides in the matrix also increased without loss of hardness. In addition, a new brand of alloy 280X29NL (sample 2), which is economically inexpensive and corrosive, was developed without compromising the mechanical properties of the alloy.

“…Accumulative roll bonding (ARB), a traditional technique of severe plastic deformation (SPD), is easily adopted by the industry because it does not need any major modifications to the conventional equipment design [ 5 ]. Since the birth of heterogeneous materials, ARB has been used to produce laminated composites [ 6 ] and metal-based composites with oxide particles [ 7 , 8 ]. Furthermore, thanks to the development of heterogeneous materials, ARB has been used to simultaneously process two or more different materials and produce laminate composites with special properties, such as Al/Mg [ 6 ], Al/Ti [ 9 ], Mg/Nb [ 10 ], and Cu/Nb [ 11 ].…”

As the applications of heterogeneous materials expand, aluminum laminates of similar materials have attracted much attention due to their greater bonding strength and easier recycling. In this work, an alloy design strategy was developed based on accumulative roll bonding (ARB) to produce laminates from similar materials. Twin roll casting (TRC) sheets of the same composition but different cooling rates were used as the starting materials, and they were roll bonded up to three cycles at varying temperatures. EBSD showed that the two TRC sheets deformed in distinct ways during ARB processes at 300°C. Major recrystallizations were significant after the first cycle on the thin sheet and after the third cycle on the thick sheet. The sheets were subject to subsequent aging for better mechanical properties. TEM observations showed that the size and distribution of nano-precipitations were different between the two sheet sides. These nano-precipitations were found to significantly promote precipitation strengthening, and such a promotive effect was referred to as hetero-deformation induced (HDI) strengthening. Our work provides a new promising method to prepare laminated heterogeneous materials with similar alloy TRC sheets.
