Lean Steels Microstructure.Steels with carbon concentrations in the range 0.8-1.1 wt% and the total substitutional solute content less than 3 wt%,designed originally for machining tools,have historically dominated the mass market for bearings [ s10,9].They can be made martensitic by quenching in oil or salt,from a temperature where the material is mostly austenite.Some results are removed in response to a notice of local law requirement.For more information,please see here.Previous123456NextSome results are removed in response to a notice of local law requirement.For more information,please see here.12345NextRole of Ag additions in the microstructural development to chemical attack and mechanical abrasion because of the metallic outer layer.For practical applications (e.g.,coils for motors and generators),however,the superconductor tapes will be subjected to large mechanical and thermal strain cycles during coil fabrication and in service.These strains are expected to cause microstructural damage
